To determine how much energy is available to the algae when there are 2,000 kcal available to the krill, we would typically need to consider the energy transfer between trophic levels in an ecosystem. Generally, only about 10% of the energy from one trophic level is transferred to the next level.
If we assume the krill are consuming the algae, then we can calculate the energy available to the algae based on this typical efficiency:
- If krill have 2,000 kcal available, and approximately 10% of energy is transferred to the krill from the algae, we can backtrack to find the energy in the algae.
Let \( x \) be the energy available to the algae. Then:
\[
0.10x = 2,000 \text{ kcal}
\]
To find \( x \):
\[
x = \frac{2,000}{0.10} = 20,000 \text{ kcal}
\]
So, the energy available to the algae would be **20,000 kcal**.
