Explanation:
Ecosystem energy flow. Energy's life moves. The energy cycle is based on the flow of energy in an ecosystem through various trophic levels. The cycling energy and nutrients obtained from various external sources maintain our ecosystem.
The responses are A, B, and E. A) Because the sun provides the entire ecosystem with energy, it is a major source of energy. B) because photosynthesis is the process in which plants convert radiant energy from the sun into chemical energy to form sugar-known glucose. E) I believe because, as it moves throughout the ecosystem, the amount of energy at each trophic level decreases.
I hope this helped!!!
Answer:Figure: The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH
