the table shows the amounts of energy found in four trophic levels of an ecosystem.

population in trophic level	energy (kcal) in trophic level
blackberry bushes	200,000
moles	2,000
foxes	200

which claim is supported by the data?
a. the first trophic level contains foxes.
b. the second trophic level contains june bugs.
c. the third trophic level contains blackberry bushes.
d. the fourth trophic level contains moles.

Explanation:

Step1: Identify producers

Producers are at first level. Black - berry bushes are producers with highest energy (200,000 kcal), so they are in first trophic level.

Step2: Identify primary consumers

Primary consumers eat producers. June bugs eat black - berry bushes and have 20,000 kcal of energy, so they are in second trophic level.

Step3: Identify secondary consumers

Secondary consumers eat primary consumers. Moles eat June bugs and have 2,000 kcal of energy, so they are in third trophic level.

Step4: Identify tertiary consumers

Tertiary consumers eat secondary consumers. Foxes eat moles and have 200 kcal of energy, so they are in fourth trophic level.

Answer:

B. The second trophic level contains June bugs.
