Food Chains and Webs Explained

What is a food chain?

• A series of events where one organism eats another and obtains energy

• A network of interconnected food webs

• A group of animals living in the same habitat

• A type of plant that grows in chains

What is a food web?

• A single linear sequence of organisms

• A complex network of interconnected food chains

• A web made by spiders to catch food

• A type of fishing net

How can environmental changes impact food chains?

• They can cause species to become extinct, disrupting the chain

• They have no impact on food chains

• They make food chains longer

• They only affect plants, not animals

Why is a balanced environment important for life?

• It ensures that all species have enough resources to survive

• It makes the environment look prettier

• It allows humans to build more houses

• It reduces the number of predators

What role do producers play in a food chain?

• They are the top predators

• They create energy from sunlight through photosynthesis

• They decompose dead organisms

• They are the primary consumers

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

• Grass

• Rabbit

• Eagle

• Mushroom

What is the main source of energy for most food chains?

• The Moon

• The Sun

• The Ocean

• The Wind

How do decomposers contribute to a food web?

• They produce energy from sunlight

• They break down dead organisms, returning nutrients to the soil

• They are primary consumers

• They hunt and eat other animals

What might happen if a top predator is removed from a food web?

• The population of prey species may increase

• The food web will remain unchanged

• New predators will immediately take its place

• All species in the web will become extinct

Which of the following is a consequence of an unbalanced ecosystem?

• Increased biodiversity

• Species extinction

• More stable food webs

• Enhanced plant growth
