1Question

Define the word 'ecosystem' in your own words. Then name two living and two nonliving parts of an ecosystem.

2Question

Explain the difference between a food chain and a food web. Use one example of each related to a forest ecosystem.

3Question

Describe how one abiotic factor, such as temperature, rainfall, or sunlight, can affect the balance of an ecosystem. Include at least one consequence for plants and one for animals.

4Question

Choose one ecosystem and explain how humans can both positively and negatively affect it. Give one example of each type of impact and explain the result.

5Question

Write a short analytical response explaining why biodiversity is important for ecosystem stability. Include how a loss of species can affect resilience, food relationships, and long-term survival of the ecosystem.

Answer Key

#	Answer
1	An ecosystem is a community of living things and the nonliving environment they interact with in a specific area. Two living parts are plants and animals. Two nonliving parts are water and sunlight.
2	A food chain shows a single path of energy transfer from one organism to another, while a food web shows many connected feeding relationships in the same ecosystem. Example of a food chain: grass → rabbit → fox. Example of a food web: grass is eaten by rabbits and insects, rabbits are eaten by foxes and hawks, and insects are eaten by birds and frogs.
3	An abiotic factor like rainfall can strongly affect ecosystem balance. If rainfall decreases, plants may grow poorly or die, which reduces food and shelter for animals. As a result, herbivores may have less to eat, and predators may also decline because their prey becomes less available.
4	In a coral reef ecosystem, humans can help by creating marine protected areas that limit fishing and allow fish populations to recover. Humans can harm coral reefs through pollution or climate change, which can bleach corals and reduce biodiversity. Positive actions support recovery, while negative actions weaken the ecosystem and disrupt species interactions.
5	Biodiversity is important because it gives an ecosystem many different species that can fill different roles. If one species declines, others may be able to take over some of its function, which helps the ecosystem stay stable. When species are lost, food relationships can break down, making it harder for organisms to find food or avoid overpopulation. Over time, low biodiversity reduces resilience, meaning the ecosystem becomes less able to recover from disease, drought, or human disturbance.
