Answer 2

In a healthy ecosystem, the trophic level that should have the most energy is the **Producers**.

### Justification:
Producers, such as plants and algae, are the first trophic level and are responsible for converting solar energy into chemical energy through the process of photosynthesis. They form the base of the food web and supply energy to all other trophic levels.

As energy moves up the food chain from producers to primary consumers, and then to higher levels like secondary and tertiary consumers, a significant amount of energy is lost at each step due to metabolic processes, heat production, and inefficiencies in energy transfer—following the 10% rule where roughly only 10% of the energy is transferred to the next trophic level. As a result, the energy available to support higher trophic levels decreases, meaning there will be less energy in secondary and tertiary consumers compared to primary producers.

Thus, the producers hold the most energy in a healthy ecosystem, forming the foundation that supports all other organisms.

Answer 3

In a healthy ecosystem, the trophic level with the most energy is the **Producers**.

### Justification:
Producers, such as plants, convert solar energy into chemical energy through photosynthesis, serving as the base of the food web. Energy decreases at each subsequent trophic level due to metabolic losses, roughly following the 10% rule, where only about 10% of energy is passed to the next level. This means producers hold the most energy, supporting all other consumers in the ecosystem.
