Question

The following flow of energy occurs in one ecosystem: flower → caterpillar → frog → heron.

Which trophic level has the most energy to pass on to the next?

Responses

frog
frog

caterpillar
caterpillar

heron
heron

flower

Answer 1

In an ecosystem, energy is most abundant at the producer level, which is the first trophic level. In this case, the producers are the flowers. As we move up the trophic levels (from flower → caterpillar → frog → heron), energy is lost at each level due to processes such as respiration, heat loss, and inefficiencies in energy transfer.

Therefore, the correct answer is:

**flower**

The flower has the most energy to pass on to the next level.
