All plants and animals in an ecosystem rely on the flow of energy. Which of the following sources do decomposers rely on for energy? A) Green grass
B) Dead plants and dead animals
C) Active rabbits
D) Flying hawks

Decomposers rely on B) Dead plants and dead animals, as a source of energy.

Explanation:

Decomposers are micro-organisms that digest things that are dead or decaying and turn the dead plants and animals into humus. They make vital nutrients available to an ecosystem’s primary producers—commonly plants and algae. Decomposers break apart complex organic materials into more elementary substances: water and carbon dioxide, plus simple compounds containing nitrogen, phosphorus, and calcium. All of these components are substances that plants need to grow.
