This video tutorial explores the roles of producers, consumers, and decomposers in ecosystems. Producers, such as plants and algae, create their own food through photosynthesis, storing energy for other organisms. Consumers, including humans and animals, rely on producers for energy, as they cannot produce their own food. Decomposers, like bacteria and fungi, break down organic matter, recycling nutrients back into the soil. The video clarifies misconceptions about these roles and distinguishes between decomposers and scavengers.

What do producers in an ecosystem do?

• They consume other organisms for energy.

• They decompose dead matter.

• They produce their own food through photosynthesis.

• They rely on the sun for movement.
