Understanding Food Chains

What is a food chain?

• A food chain is a type of restaurant.

• A food chain is a sequence of organisms each dependent on the next as a source of food.

• A food chain is a group of people who eat together.

• A food chain is a method of cooking food.

Name the first link in a food chain.

• Producer

• Consumer

• Decomposer

• Herbivore

What do we call organisms that produce their own food?

• Decomposers

• Autotrophs

• Heterotrophs

• Saprophytes

Which type of organism eats plants?

• Carnivores

• Herbivores

• Omnivores

• Decomposers

What is a primary consumer?

• An organism that feeds on primary producers.

• A type of plant that produces energy through photosynthesis.

• An organism that feeds on secondary consumers.

• An animal that primarily eats other animals.

Give an example of a secondary consumer.

• Frog

• Deer

• Rabbit

• Grasshopper

What role do decomposers play in a food chain?

• Decomposers produce energy for herbivores.

• Decomposers are primary consumers in a food chain.

• Decomposers recycle nutrients and support plant growth in a food chain.

• Decomposers only break down plastic waste.

How does energy flow in a food chain?

• Energy flows from producers to consumers in a food chain.

• Energy is recycled within the same trophic level in a food chain.

• Energy flows from consumers to producers in a food chain.

• Energy is created by consumers in a food chain.

What happens if one link in the food chain is removed?

• The ecosystem may become unbalanced, affecting all organisms.

• All organisms will thrive without any changes.

• The food chain will become stronger and more efficient.

• The removed link will regenerate immediately.

Why are food chains important for ecosystems?

• Food chains are only important for human consumption.

• Food chains are important for ecosystems because they demonstrate the interdependence of organisms and the flow of energy and nutrients.

• Food chains are solely based on plant growth.

• Food chains have no impact on the environment.
