Photosynthesis creates G3P at the end of the Calvin Cycle which goes on to power the first stage of cellular respiration, glycolysis.
<h2>Energy </h2>
Explanation:
Energy flows in only one direction through an ecosystem
- The Sun supports most of Earth's ecosystems
- Plants create chemical energy from abiotic factors that include solar energy and chemosynthesizing bacteria create usable chemical energy from unusable chemical energy
- The food energy created by producers is passed to consumers, scavengers, and decomposers
- Energy flows through an ecosystem in only one direction, it is passed from organisms at one trophic level or energy level to organisms in the next trophic level
- Most of the energy at a trophic level – about 90% – is used at that trophic level and organisms need it for growth, locomotion, heating themselves, and reproduction
- So animals at the second trophic level have only about 10% as much energy available to them as do organisms at the first trophic level
- Animals at the third level have only 10% as much available to them as those at the second level
It seems that you have missed the necessary options to answer this question, but anyway the answer for this would be 20%. The mighty Amazon River of South America carries 20% of the world's fresh water. It is considered as <span>the largest river by discharge of water in the world. Hope this answers your question. </span>
