Ch._8_Short_Answer.pdf - Name Date AP\/College Biology Ch 8 Photosynthesis Short Answer Questions 1 What is the role of photosynthesis in the ecosystem 2 Sunlight provides light energy that allows photosynthesis … The trade-off between photosynthesis and transpiration through stomata, the water-use efficiency (WUE), is an important driver of plant evolution and ecosystem … During photosynthesis, plants take carbon dioxide from the air and used it to make glucose (stored carbon), while releasing oxygen. Sunlight makes it possible for aquatic predators to see their prey underwater. While photosynthesis requires energy (in most cases, light energy) to occur, respiration releases energy. Photosynthesis helps in the process of cycling of minerals in an ecosysye especially oxygen cycle. Why is photosynthesis important to most ecosystems. Topic 2: Ecosystems 2.2: Function of Ecosystems 2.2.2: Photosynthesis and Respiration in Ecosystems Inputs of Water, Carbon Dioxide Photosynthesis Involves Light energy is trapped and Sunlight by the chlorophyll inside the chloroplasts •Inputs •Processes •Outputs Oxygen is realesed Energy is … Energy enters the system through photosynthesis and is incorporated into plant tissue. Light is the most important of them all. They can encourage the breed of the marine animals and increase the population of marine ecosystem by providing the safe habitats. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. Primary producers convert chemical energy to light energy b. Important Words Photosynthesis is when palnts use the sun for nuterients and food. Without photosynthesis, the whole marine ecosystem will eventually suffers. Autotrophs. A part of the energy is stored within the plants. Importance Of Ecosystem An ecosystem can be defined as the biological community of living beings, communicating with the physical environment and other nonliving components. Now photosynthesis is something that is performed creatively by organisms such as plants, algae, and some bacteria. The interactive nature of the two is represented best … 2. Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. The more carbon dioxide (CO 2) plants and trees absorb during photosynthesis, the process they use to make food, the less CO 2 remains trapped in the atmosphere, where it can cause temperatures to rise. For example, the carbon cycle is tied to the availability of oxygen in the atmosphere. The process of photosynthesis is crucially important to the biosphere for the following reasons: It creates O 2 , which is important for two reasons. The carbon cycle is tied to the availability of other elements and compounds. The results of the study also highlight the importance of the role of ecosystems in the global carbon cycle. The remaining energy is utilised by the plants in their growth and development. Land ecosystems currently play a key role in mitigating climate change. Iron fertilization is the intentional introduction of iron to iron-poor areas of the ocean surface to stimulate phytoplankton production. Light. Cellular respiration and photosynthesis are opposite, but equal in a way. It … Nurse Log is a rotten log that is a home to many plants and samll creatures Photosynthesis is one of the most important contributors to numerous of things, ranging from maintaining the ecosystem stable to producing oxygen for the entire world. Finally, ecosystems link us together culturally, as we share in appreciating the beauty of the outdoors through recreation, education, and spiritual uses. 4. Factors such as quality of light, intensity of light and the length of the light period (day length) play an important part in an ecosystem. Sunlight keeps harmful bacteria from taking over aquatic ecosystems. More light is now being shed on the part played by terrestrial ecosystems in the global carbon cycle. This applies to the role of photosynthesis, whereby plants fix carbon dioxide, as well as the process of respiration, during which plants release carbon dioxide once again. Although efficient light absorption is important for photosynthesis, UV and excess light absorption damages photosynthetic apparatus. The importance of the phytoplankton is one of the things that make marine ecosystems unique and different from land ecosystems … Although photosynthesis is most commonly associated with plants, microbial photosynthesis is also a significant supplier of chemical energy, fueling many diverse ecosystems. Photosynthesis is important because it helps in maintaining a balanced level of oxygen and carbon dioxide in the atmosphere. Photosynthesis and cellular respiration are very important in the production of energy. Oxygen is utilised in the … Through photosynthesis, plants harvest the energy of the sun, providing both food and … Which is the most correct statement about the role of photosynthesis in an ecosystem? Visible light is of the greatest importance to plants because it is necessary for photosynthesis and rest of the solar energy either reflected or absorbed by atmosphere. The ecosystem surrounding the vents has a diverse array of animals, such as tubeworms, crustaceans, and octopi that derive energy from the bacteria. The energy flow in the ecosystem is important to maintain an ecological balance. In the photlysis water oxygen is released in the atmosphere. Photosynthesis uses light energy from the sun to. Climate Change. The importance of photosynthesis is not just that it can capture sunlight’s energy. Half of all the glucose created by the plant is used in respiration to make energy available for cellular processes. a. make their own food. power a chemical process and make organic molecules. Seed Dispersal is what plants use to disperse their seeds so they can grow more. Plants act as producers at the start of all food chains, making food from the process of photosynthesis . According to Poulter, going forward, the decreasing carbon-uptake efficiency of land ecosystems means we may see the amount of CO2 remaining in the atmosphere after fossil fuel burning and deforestation start to … According to my reading, energy is the strength and vitality to sustain physical or mental activity as it relates to humans (McKean, 1995).Energy is intertwined in all living things because plants are eaten by herbivores, and meat … Dim conditions will cause photosynthesis to slow down. Forests play an important role in the purification of the atmospheric air. The higher amount of light that can penetrate the water, the better the photosynthesis is. Supporting. An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. Plants givve the animals energy to keep the ecosystem healthy. Energy flows through an ecosystem in a number of food chains. The ocean ecosystems are an important source of atmospheric oxygen due to the vast population of autotrophic algae releasing oxygen through photosynthesis. Algae can influence the earth’s climate significantly. Land ecosystems currently play a key role in mitigating climate change. Forests remove about 30% of anthropogenic CO2 emissions through photosynthesis and return almost 40% of incident precipitation back to the atmosphere via transpiration. Heterotrophs. Other simulations suggest that (1) over time scale of days to years, ecosystem C seq is regulated mainly by flexibility in the C and N stoichiometric relationship, due to instantaneous increases in net primary productivity (NPP) through a stimulation of photosynthesis and enhanced uptake of available N by … We know there two events in an ecosystem, they are flow of energy and cycling of minerals. Glucose can then be converted into carbohydrates. This is intended to enhance biological productivity and/or accelerate carbon dioxide (CO 2) sequestration from the atmosphere.. Iron is a trace element necessary for photosynthesis in plants. Photosynthesis also helps in converting inorganic raw materials into food that provides our ecosystem … Photosynthesis is important to food chains because creatures capable of photosynthesis form the foundation of most food chains. Plants form the critical base of food chains in nearly all ecosystems. The molecular oxygen in Earth’s atmosphere was created by photosynthetic organisms; without photosynthesis there would be no O 2 to support cellular respiration (see chapter … Sunlight provides a source of heat energy to increase water temperatures. During the day, trees and plants absorb carbon dioxide for photosynthesis and give out oxygen. It can also be defined as the chain of communication or interaction between the living organisms and their environment. Read also importance of artificial coral reefs. Maitain the oxygen cycle in an ecosystem. As such, they help in the purification of the air that we breathe. Many of these carbohydrates are produced by photosynthesis, the biochemical process by which phototrophic organisms convert solar energy (sunlight) into chemical energy. By feeding on plants and on one another, animals play an important role … The carrying capacity is a measure of how many individuals can a given ecosystem provide for. Which of the following explains why sunlight is important to aquatic ecosystems? Both types of producers are important in marine ecosystems however the phytoplankton based ecosystems are more common. A lizard sunning itself on a cold day can use the sun’s energy to warm up. In other words, ... Pond Ecosystem Lesson for Kids Photosynthesis is very important in maintaining a balance in the ecosystem. Primary consumers rely directly on light energy c. Primary producers convert light energy to chemical energy as a service to the ecosystem, not for their own gain d. Sustainability is the ability of the ecosystem to maintain its ecological processes, the composting of debris into soil, the exchange of carbon and air, the production of rainfall, photosynthesis, the life-giving processes required to maintain life as we know it on earth. Marine ecosystems are regarded as the most abundant type of ecosystems … These biotic and abiotic components are linked together through nutrient cycles and energy flows. In terrestrial environments, portion of incident solar radiation reaches to the surface, which are called direct radiation (PAR dir ), while the other are optically altered by the Earth’s … Without it, photosynthesis is impossible.
