Which food chain correctly describes the flow of energy in an ecosystem?

• Grass-->cow-->human

• Caterpillar-->leaf-->human

• Leaf-->bird-->caterpillar

• Leaf-->bird-->caterpillar

Which of these is the example of a decomposer?

• Fish

• Snake

• Bird.

• Bacteria

How do decomposers help other organisms in an ecosystem?

• They use the sunlight to make their own food that other organisms eat for energy.

• Decomposers do not help other organisms in an ecosystem.

• They break down dead organisms and add nutrients back to the soil that plants use.

• They help disperse seeds for plant growth.

• Fox

What type of diet does a herbivore follow?

• They eat only plants

• They eat both plants and meat

• They eat only meat

• They eat insects

Which of the following best describes a food web?

What role do carnivores play in an ecosystem?

• They produce energy through photosynthesis.

• They consume herbivores and help control their population.

• They decompose organic matter.

• They primarily eat plants.

Which of the following is an example of a secondary consumer?

• Grass

• Rabbit

• Fox

• Fungi

What is the primary function of producers in an ecosystem?

• To consume other organisms for energy.

• To break down dead matter.

• To convert sunlight into energy through photosynthesis.

• To provide shelter for other organisms.

What is the significance of biodiversity in an ecosystem?

• It reduces competition among species.

• It increases the resilience of the ecosystem.

• It makes the ecosystem less stable.

• It is not important for ecosystem health.
