These are the hands of an ecosystem. It includes producers, consumers, and decomposers. Producers are autotrophs which means they can synthesize their own food. Producers are doors that provide food, shelter, and oxygen to the consumers. Consumers are heterotrophs which means they feed on others. They obtain energy from producers directly or indirectly. Decomposers include microorganism which feeds on the dead and decaying body of other organisms. So take this quiz and increase your knowledge about biotic factors of the ecosystem.
