Ecosystem Roles and Consumer Types

The video tutorial explains photosynthesis as the process by which green plants make food using water, carbon dioxide, chlorophyll, and sunlight. It then introduces consumers, categorizing them into primary, secondary, tertiary, omnivores, parasites, scavengers, and decomposers. Each type is explained in detail, highlighting their roles in the ecosystem. The tutorial concludes with activities for students to categorize animals and unscramble words related to the topic.

What is the primary role of chlorophyll in photosynthesis?

• To produce carbon dioxide

• To release oxygen

• To capture sunlight

• To absorb water

Which of the following is NOT a type of consumer?

• Photosynthetic consumer

• Tertiary consumer

• Primary consumer

• Secondary consumer

Which animals are considered primary consumers?

• Deer

• Lions

• Snakes

• Eagles

What type of consumer is a lion?

• Secondary consumer

• Primary consumer

• Omnivore

• Herbivore

Which of the following animals is an omnivore?

• Cow

• Tiger

• Vulture

• Bear

How do parasites obtain their food?

• By hunting other animals

• By photosynthesis

• By feeding on dead matter

• By harming their hosts

What role do scavengers play in the ecosystem?

• They are primary consumers

• They produce food for plants

• They decompose dead matter

• They clean the environment by eating dead animals

Which organisms are responsible for decomposing dead matter?

• Herbivores

• Omnivores

• Carnivores

• Bacteria and fungi

What is the main benefit of decomposers in the ecosystem?

• They provide food for carnivores

• They recycle nutrients back into the soil

• They produce oxygen

• They consume living plants

Without decomposers, what would happen to the Earth?

• It would be covered in dead matter

• It would have less oxygen

• It would have more plants

• It would have more animals
