Food Chain Skills Assessment

Give an example of a producer in a food chain.

• lion

• plant

• whale

• sun

Explain the difference between primary consumers and secondary consumers.

• Primary consumers feed on secondary consumers, while secondary consumers feed on plants.

• Primary consumers feed on plants, while secondary consumers feed on primary consumers.

Describe how energy flows through a food chain.

• Energy flows through a food chain by herbivores consuming sunlight directly

• Energy flows through a food chain by organisms creating energy from nothing

• Energy flows through a food chain as organisms consume each other, starting from producers capturing energy from the sun, then passing through herbivores, carnivores, and decomposers.

Why are producers essential for the survival of a food chain?

• Producers convert sunlight into energy through photosynthesis, which is the initial source of energy for all other organisms in the food chain.

• Producers do not contribute to the energy flow in the food chain

• Producers consume energy from other organisms in the food chain

• Producers are not important in a food chain

Describe the relationship between herbivores and plants in a food chain.

• Herbivores eat other animals as their main food source in a food chain.

• Herbivores eat plants as their main food source in a food chain.

Give an example of a complete food chain including producers, consumers, and decomposers.

• Grass (producers) -> Lions (primary consumers) -> Mice (secondary consumers) -> Fungi (decomposers)

• Plants (producers) -> Rabbits (primary consumers) -> Octopuses (secondary consumers) -> Bacteria (decomposers)

What is the main role of consumers in a food chain?

• Consumers convert sunlight into energy through photosynthesis.

• Consumers regulate the population of producers in a food chain.

Explain the role of carnivores in a food chain.

• Carnivores feed on plants as their main food source.

• Carnivores feed on other animals as their main food source and they balance the ecosystem.

Why is it important to maintain a balanced food chain?

• A balanced food chain ensures that all organisms have enough food to survive.

• A balanced food chain is not important for ecosystem stability.

Describe the role of omnivores in a food chain.

• Omnivores feed on both plants and animals as their main food source.

• Omnivores feed only on plants in a food chain.
