What is a food chain?

• A food chain is a type of restaurant.

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

• A food chain is a method of cooking food.

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

Name the first link in a food chain.

• Decomposer

• Producer (e.g., plants)

• Carnivore

• Herbivore

What do we call organisms that produce their own food?

• Autotrophs

• Decomposers

• Saprophytes

• Heterotrophs

Give an example of a primary consumer.

• Frog

• Deer

• Grass

• Rabbit

What role do decomposers play in a food chain?

• Decomposers are the primary producers in a food chain.

• Decomposers produce energy for consumers.

• Decomposers compete with herbivores for resources.

• Decomposers recycle nutrients and support the growth of producers in a food chain.

How does energy flow in a food chain?

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

• Energy flows in a circular pattern among all organisms in a food chain.

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

• Energy is created and consumed in equal parts in a food chain.

What is a predator?

• An organism that only eats plants.

• A type of animal that lives in water.

• A creature that scavenges dead organisms.

• An organism that hunts and consumes other organisms for food.

Name a secondary consumer in a food chain.

• Rabbit

• Grasshopper

• Deer

• Fox

What happens if one species in a food chain goes extinct?

• The ecosystem becomes more stable after a species goes extinct.

• The extinction of one species has no impact on the food chain.

• Only the extinct species is affected, while others remain unchanged.

• The extinction of one species can disrupt the food chain, affecting multiple species and the ecosystem.

Why are food chains important for ecosystems?

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

• Food chains are irrelevant to the survival of species.

• Food chains have no impact on energy flow in ecosystems.

• Food chains are only important for human consumption.
