Answer;
D. Most of the energy from photosynthesis flows out as heat
Explanation;
Energy flow is the amount of energy that moves through a food chain in a given ecosystem.
Producers such as green plants in a ecosystem convert energy from the the sun into carbon bonds, such as those found in the sugar glucose through the process of photosynthesis.
The amount of chemical energy storied as nutrients in the bodies and wastes of organisms flows through ecosystems from one trophic level to the next and through this flow energy also is lost as heat. And the chemical energy available to the succeeding feeding level decreases.
That would be a covalent bond. Hope this helps!
