What is the primary source of energy in most food chains?

• Producers

• Sunlight

• Decomposers

• Herbivores

In a simple food chain, which of the following is a primary consumer?

• Grass

• Lion

• Grasshopper

• Snake

Which of the following is the correct order of a basic food chain?

• Grass → Grasshopper → Frog → Snake → Eagle

• Grass → Snake → Frog → Grasshopper → Eagle

• Grass → Frog → Grasshopper → Snake → Eagle

• Eagle → Grasshopper → Frog → Grass → Snake

Which of the following statements is true about food chains?

• All food chains start with a carnivore.

• Producers are always at the top of the food chain.

• A food chain shows a linear flow of energy between organisms.

• Secondary consumers are always herbivores.

What role do decomposers play in a food web?

• They recycle nutrients back into the ecosystem by breaking down dead organisms.

• They are primary consumers.

• They produce food through photosynthesis.

• They prevent the growth of plants.

Which of the following is an example of a tertiary consumer in a food chain?

• Grass

• Rabbit

• Lion

• Butterfly

In a food web, why is it important to have multiple paths of energy flow?

• It reduces competition among herbivores.

• It provides more energy to decomposers.

• It increases the ecosystem's stability and resilience.

• It helps predators become producers.

What would likely happen if the primary producers in a food web disappeared?

• There would be an increase in herbivores.

• The food web would collapse, and many species would die off.

• Primary consumers would become producers.

• Predators would become producers.

In an aquatic food chain, what might be a primary consumer?

• Shark

• Algae

• Plankton

• Coral

Which of the following best defines a food web?

• A linear sequence of energy transfer between organisms.

• A network of interrelated food chains showing various paths of energy flow.

• A collection of organisms that live in the same environment.

• A set of organisms that all belong to the same species.
