Let's determine which trophic level each population occupies based on the energy data given in the table.
1. Blackberry bushes: 200,000 kcal
2. June bugs: 20,000 kcal
3. Moles: 2,000 kcal
4. Foxes: 200 kcal
Trophic levels are usually categorized by the amount of energy they possess. The higher the energy, the lower the trophic level (producers usually have the highest energy). Let’s rank the populations based on their energy from highest to lowest to identify their respective trophic levels:
1. First Trophic Level: The group with the highest energy, which is Blackberry bushes with 200,000 kcal.
2. Second Trophic Level: The next group with the second-highest energy, which is June bugs with 20,000 kcal.
3. Third Trophic Level: The group with the third highest energy, which is Moles with 2,000 kcal.
4. Fourth Trophic Level: The group with the lowest energy, which is Foxes with 200 kcal.
Given these rankings, let's examine each claim:
- Claim A: The first trophic level contains foxes.
- The first trophic level actually contains Blackberry bushes, not foxes. Therefore, this claim is False.
- Claim B: The second trophic level contains June bugs.
- The second trophic level indeed contains June bugs. Therefore, this claim is True.
- Claim C: The third trophic level contains blackberry bushes.
- The third trophic level actually contains Moles, not Blackberry bushes. Therefore, this claim is False.
- Claim D: The fourth trophic level contains moles.
- The fourth trophic level actually contains Foxes, not Moles. Therefore, this claim is False.
Summarizing the results:
- Claim A: False
- Claim B: True
- Claim C: False
- Claim D: False
Thus, the claim supported by the data is:
B. The second trophic level contains June bugs.
