Why are decomposers important in an ecosystem?

• They break down dead organisms and organic matter, returning essential nutrients to the soil for plants to use.

• They help in the growth of plants

• They contribute to air pollution

• They are harmful to the ecosystem

How do decomposers contribute to food chains?

• By providing energy to the producers

• By hunting and consuming other organisms

• By breaking down dead organisms and organic matter, releasing nutrients back into the ecosystem.

Explain the process of decomposition.

• Decomposition is caused by extreme heat and pressure

• Decomposition is a process of combining different substances to form organic matter

• Decomposition is a result of inorganic matter breaking down into simpler substances

• Organic matter is broken down into simpler substances by microorganisms

What happens to the nutrients when decomposers break down organic matter?

• Stored in the atmosphere

• Sent into space

• Released back into the soil

• Disposed in the ocean

How do decomposers help in recycling nutrients in an ecosystem?

• By breaking down dead organisms and waste materials, releasing nutrients back into the soil or water.

• By preventing the breakdown of dead organisms

• By consuming nutrients from the soil
