Decomposers are important to ecosystems because they

• release carbon trapped in dead matter

• capture energy from the Sun

• are producers

• can be omnivores

A consumer gets energy by

• absorbing sunlight.
• breaking down dead organisms.
• soaking it up from the ground.
• feeding on other organisms.

The cycling of matter is important because

• Matter is created and destroyed

• Only a limited amount of matter is available so it has to be recycled
• Matter can only be found in water

• Bacteria use matter to convert organisms into solar energy
