Given a simple food web with grass, grasshoppers, frogs, and snakes, identify the correct sequence of energy transfer.

Snake → Frog → Grasshopper → Grass

Grasshopper → Grass → Frog → Snake

Grass → Snake → Frog → Grasshopper

In a local pond, algae grow rapidly when fertilizer runs off from nearby farms. Which limiting factor has changed, and how does it affect the ecosystem?

Food increased, causing algae to overpopulate

Water decreased, causing algae to die

Disease increased, reducing algae

Space increased, causing algae to spread

A student is given a diagram of a food web and asked to identify which organism is both a consumer and a prey. What should the student look for?

An organism that eats others and is eaten by another

An organism that only produces energy

An organism that decomposes dead matter

An organism that is not connected to others

A disease spreads through a population of rabbits, causing their numbers to drop. What is the best explanation for this change?

Disease is a limiting factor that reduced the rabbit population

Food supply increased, so rabbits left

Water supply increased, so rabbits died

Space increased, so rabbits moved away

A farmer notices that after removing all the grasshoppers from his field, the population of frogs decreases. Using your knowledge of food webs, explain why this happened.

Frogs lost a food source, so their population decreased

Frogs had more food, so their population increased

Grasshoppers ate frogs, so removing them helped frogs

Frogs are decomposers, so they were unaffected

A student observes that in a local park, squirrels and birds both use tree holes for nesting. Over time, the number of available tree holes decreases. Predict what will happen to the populations of squirrels and birds, and explain your reasoning.

Both populations will decrease due to increased competition for nesting sites

Both populations will increase because they share resources

Only squirrels will decrease, birds will increase

Only birds will decrease, squirrels will increase

A scientist introduces a new species of fish into a lake. The new fish eats the same food as a native fish species. Predict and explain what might happen to the native fish population.

The native fish population may decrease due to competition for food

The native fish population will increase because of more food

The native fish population will not be affected

The native fish population will become decomposers

A severe drought reduces the amount of water in a wetland. Using your understanding of limiting factors, explain how this might affect the populations of plants and animals in the wetland.

Populations of both plants and animals will likely decrease due to less available water

Populations will increase because there is less water to share

Only animal populations will decrease, plants will increase

Only plant populations will decrease, animals will increase
