Food Chains: Producers, Consumers, and Decomposers

The video explains how plants make their own food through photosynthesis, using light energy from the Sun. It categorizes living things into producers, consumers, and decomposers. Producers, like plants and algae, create their own food. Consumers, including animals and humans, obtain energy by eating other organisms. Decomposers, such as fungi and bacteria, break down dead matter, recycling nutrients back into the ecosystem.

What do plants use from the Sun to create their own food?

• Heat energy

• Light energy

• Magnetic energy

• Sound energy

Which of the following is NOT a producer?

• Lion

• Flower

• Tree

• Grass

What is the primary role of consumers in an ecosystem?

• To provide nutrients to the soil

• To produce their own food

• To decompose dead matter

• To consume other organisms for energy

Which of the following is an example of a consumer?

• Algae

• Human

• Bacteria

• Mushroom

How do decomposers contribute to the ecosystem?

• By providing light energy
