Question

Why do autotrophs always occupy the lowest?

Answer 1

Autotrophs:

1. Autotrophs are capable of producing their own food through photosynthesis.
2. The autotroph itself provides food for all other creatures by obtaining food.

Autotrophs always occupy the lowest levels because:

1. The sun's energy is converted into biomass by food web maker Autotrophs.
2. Each trophic layer leads to a decrease in biomass.
3. Lower trophic levels always contain more biomass than higher trophic levels.
4. In the Healthy Food Web, vegetarians always have more autotrophs as the biomass always decreases with each trophic level.
5. Autotrophs act as a bridge between solar energy and species that are unable to produce their own food.
