What is an explanation of why producers are always found at the lowest trophic level?

Producers are autotrophs and do not depend on other trophic level organisms for their food.

Explanation:

Producers are autotrophs and produce their food from sunlight through photosynthesis. They convert sunlight into chemical energy which is transferred to other trophic levels such as primary consumers, secondary consumers, and others if present.

All the trophic levels other than producers are depending on the producers or other trophic levels for their food.

Thus, producers are always found at the lowest trophic level.

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a
