Food Chains

What are producers in a food chain?

• Organisms that consume other organisms for food.

• Organisms that produce their own food through photosynthesis or chemosynthesis.

• Organisms that break down dead organic matter.

• Organisms that live in extreme environments.

Give an example of a producer.

• Rocks

• Animals

• Clouds

• Plants

What do consumers do in a food chain?

• Consumers eat other organisms in a food chain.

• Consumers regulate the temperature in a food chain.

• Consumers provide shelter for other organisms in a food chain.

• Consumers produce food in a food chain.

Name a consumer in a food chain.

• rabbit

• sunflower

• algae

• grasshopper

Explain the role of decomposers in a food chain.

• Decomposers break down dead organisms and organic matter, releasing nutrients back into the ecosystem.

• Decomposers create new organisms in the food chain.

• Decomposers primarily feed on live organisms in the food chain.

• Decomposers reduce the amount of nutrients in the ecosystem.

Provide an example of a decomposer.

• Fungi

• Birds

• Bacteria

• Plants

Differentiate between a food chain and a food web.

• A food chain is a visual representation of the flow of energy and nutrients in an ecosystem, while a food web is a list of food items consumed by an organism.

• In a food chain, organisms are arranged in a linear sequence of who eats whom, while a food web consists of multiple interconnected food chains showing a more complex network of interactions.

• In a food chain, all organisms are producers, while in a food web, all organisms are consumers.

• A food chain is always more complex than a food web due to the number of interactions involved.

How does energy transfer occur in a food chain?

• Energy transfer in a food chain occurs through the exchange of gases between organisms.

• Energy transfer in a food chain occurs through the consumption of organisms at different trophic levels.

• Energy transfer in a food chain occurs through the process of evaporation.

• Energy transfer in a food chain occurs through photosynthesis only.

Describe a simple food chain with three organisms.

• Sun -> Grass -> Wolf

• Sun -> Grass -> Rabbit -> Fox

• Sun -> Grass -> Deer

• Sun -> Grass -> Fox

Why are food chains important in an ecosystem?

• Food chains disrupt the balance of an ecosystem

• Food chains demonstrate the transfer of energy and nutrients between organisms in an ecosystem.

• Food chains only benefit one species in an ecosystem

• Food chains are not important in an ecosystem
