Although some ecosystems may be insensitive to species loss, due to variations in ecosystem types, or the presence of multiple species that perform a similar role, or due to their relative unimportance, or because of other abiotic factors, it is clear that higher numbers of species are needed to ensure stable provision of ecosystem services. Students were asked to identify the key metabolic processes (photosynthesis and cellular respiration) depicted in a visual representation of a carbon cycle and to explain the role of energy in both processes. An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. Edit. Photosynthesis is a process in which green plants create energy to allow using carbon dioxide and water. A diagram that shows the amount of energy that moves from one feeding level to another in a food web. The role of water in photosynthesis is to: provide electrons. Most of the planet is covered with water and the collective photosynthesis of lowly algae is the true oxygen machine. Photosynthesis occurs only when plants can obtain carbon dioxide, water and light from their external environment, products produced are sugars and oxygen. What is Ecosystem? Where does the light reaction take place? Photosynthesis is an important biochemical pathway involving the production of sugar (glucose) from light, water and carbon dioxide and releasing oxygen. An organelle that breaks down glucose to release energy for the cell during cellular respiration - this organelle is known as the powerhouse of the cell. there is no sunlight: Plankton forms what part of the food chain?
