2. Food!! All energy in the living world comes from them!
3. Preventing high levels of erosion.

Answer 2

1. Autotrophs are the start of the food chain. Without them, we would all starve, as there would be no plants, and as a result, no animals.

2. By photosynthesis, they release oxygen back to the environment.

3. Autotrophs are part of the environment. In the form of plants, they hold together the soil, prevent erosion, lower the temperature, and affect the weather and climate.
