All of these are correct. 15. Compare this food chain: algae ? water fleas ? fish ? green herons with this food chain: trees ? tent caterpillars ? red-eyed vireos ? hawks Both water fleas and tent caterpillars are a. carnivores. b. primary consumers. c. detritus feeders. d. present in grazing and detrital food webs. e. Both a and b are correct.

Step 1

According to the 10% rule, only 10% of the energy is actually transferred to the next trophic level, while the rest is lost as heat or used for other purposes. Therefore, the correct answer is **a. respired and becomes heat**. Show more…
