Understanding the Food Chain

What is the first link in a food chain?

• Producer (e.g., plants)

• Decomposer (e.g., fungi)

• Primary consumer (e.g., herbivores)

• Secondary consumer (e.g., carnivores)

Which of the following is a primary consumer?

• Grass

• Eagle

• Frog

• Rabbit

What do we call organisms that make their own food?

• Saprotrophs

• Autotrophs

• Decomposers

• Heterotrophs

Which of these is a secondary consumer?

• Rabbit

• Fox

• Grasshopper

• Deer

What role do decomposers play in a food chain?

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

• Decomposers produce energy for consumers.

• Decomposers compete with herbivores for resources.

• Decomposers are the primary producers in a food chain.

Which of the following is a producer?

• Plant

• Deer

• Fungi

• Bacteria

What is a food web?

• A food web is a type of fruit salad.

• A food web is a collection of recipes for cooking.

• A food web is a single food chain in isolation.

• A food web is a system of interrelated food chains in an ecosystem.

What do herbivores eat?

• Herbivores eat meat.

• Herbivores eat plants.

• Herbivores eat insects.

• Herbivores eat fungi.

Which animal is at the top of the food chain?

• Apex predators such as the great white shark or the African lion.

• Small predators like foxes

• Herbivores like deer

• Omnivores such as bears

What happens if a primary consumer is removed from the food chain?

• The primary consumer will thrive without competition.

• Other consumers will take over the primary consumer's role without any impact.

• The ecosystem will become more stable and resilient.

• The food chain becomes unbalanced, affecting the entire ecosystem.
