Food Chain and Ecosystem Roles

The video tutorial introduces the concept of the food chain, explaining how energy flows from the sun to producers, consumers, and decomposers. Key vocabulary such as herbivore, carnivore, omnivore, producer, consumer, and decomposer are defined. The video provides examples of food chains in nature, illustrating how energy is transferred from one organism to another. It concludes with review questions to reinforce the learning objectives.

What is the primary role of a producer in the food chain?

• To consume other animals

• To decompose dead matter

• To create its own food using sunlight

• To provide shelter for animals

Which type of animal only eats plants?

• Carnivore

• Herbivore

• Omnivore

• Decomposer

What is the main function of a decomposer in the ecosystem?

• To hunt other animals

• To consume only plants

• To break down dead plants and animals

• To produce energy from sunlight

How does energy initially enter the food chain?

• Via decomposers

• From the sun to producers

• Through carnivores

• Through herbivores

In a marine food chain, what typically eats small fish?

• Herbivores

• Plants

• Big fish

• Decomposers

What happens to a rabbit's body after it dies in the food chain?

• It becomes a producer

• It is broken down by decomposers

• It is consumed by herbivores

• It is eaten by the sun

Which of the following is an example of an omnivore?

• Decomposer

• Human

• Rabbit

• Eagle

What is the role of the sun in the food chain?

• To provide energy to decomposers

• To break down dead matter

• To give energy to producers

• To consume plants

Which of the following is NOT a consumer?

• Producer

• Herbivore

• Omnivore

• Carnivore

What is the sequence of energy transfer in a food chain?

• Decomposer -> Consumer -> Producer

• Sun -> Producer -> Consumer

• Producer -> Consumer -> Decomposer

• Consumer -> Producer -> Sun
