They break down dead organisms and recycle nutrients back into the environment

They produce their own food through photosynthesis

They consume other organisms for energy

They are the top predators in the food chain

Having too many trophic levels is inefficient because so much energy is lost as heat.

Due to the recycling of decomposers, all the lost energy can be reused by producers.

Plants are able to use 90% of the sunlight that reaches the surface of the earth.

Every consumer relies on some producer for energy.

Humans rely on producers' ability to convert solar energy for their survival.
