Producers, Consumers, and Decomposers

The video tutorial explains the energy flow in ecosystems, starting with plants that produce energy through photosynthesis by converting sunlight into usable energy. It then describes consumers, such as animals, that obtain energy by eating plants or other animals. Finally, it covers decomposers, like fungi and bacteria, which break down dead organisms, returning nutrients to the soil.

What is the process called where plants convert sunlight into energy?

• Fermentation

• Photosynthesis

• Respiration

• Transpiration

Which of the following is an example of a consumer?

• A tree

• A donkey eating grass

• A mushroom

• A bacterium

What do consumers rely on for their energy?

• Sunlight

• Soil

• Water

• Plants or animals

Which organisms are responsible for breaking down dead matter in ecosystems?

• Consumers

• Predators

• Producers

• Decomposers

What is the main benefit of decomposers breaking down dead matter?

• They produce energy

• They create new plants

• They consume other organisms

• They return nutrients to the soil
