Step 1
Completing the question information:
-Organisms : 3ª order heterotrophs are the large carnivores (wolves, hawks ); 2ª order heterotrophs are the small carvivores (snakes, owls); 1ª order heterotrophs are the herbivores (insects, small mammals); producers (plants).
- Energy: 6, 61, 623, and 6,011, respectively.
- Energy efficiency: 0.098, 0.098, 0.10, and 6,011, respectively.
Step 2
With the data and knowing about the energy flow in a pyramid of trophic level we can conclude that:
The producers with 6,011 of energy available are the trophic level with most energy, as well as that being based on the fact that it is a group formed by autotrophic organisms.
