The right answer for the question that is being asked and shown above is that: "d. all of the above." Energy in most ecosystems must flow through autotrophs because heterotrophs only generate a small fraction of their energy from photosynthesis; only autotrophs can convert solar energy into chemical energy; autotrophs are simpler organisms than heterotrophs
Answer: Option A
Explanation:
Only autotrophs have the ability to convert solar energy into chemical energy by the process known as photosynthesis. The autotrophs can trap all the radiant energy and only 10% of total energy that autotrophs have is transferred to another tropic level.
The energy from the producers are transferred to the herbivores and 10% of the total energy the herbivores have is transferred to another levels.
So, the energy flow takes place through the autotrophs because only they have the ability to perform photosynthesis.
