What is a food web?

Back

A food web is a complex network of feeding relationships among various organisms in an ecosystem, illustrating how energy and nutrients flow through different trophic levels.

Front

What is the role of producers in a food web?

Back

Producers, such as plants and algae, are organisms that create their own food through photosynthesis and serve as the primary energy source for consumers in a food web.

Front

Define decomposers and their role in an ecosystem.

Back

Decomposers are organisms, such as bacteria and fungi, that break down dead organic matter, recycling nutrients back into the ecosystem.

Front

Front

Explain the significance of arrows in a food web diagram.

Back

Arrows in a food web represent the flow of energy from one organism to another, indicating who eats whom.

Front

What is the difference between a food chain and a food web?

Back

A food chain is a linear sequence of organisms where each is eaten by the next, while a food web is a more complex network of interconnected food chains.

Front

What are primary consumers?

Back

Primary consumers are herbivores that eat producers (plants) to obtain energy.

Front

What are secondary consumers?

Back

Secondary consumers are organisms that eat primary consumers, typically carnivores or omnivores.

Front

What is a trophic level?

Back

A trophic level is a position in a food web or chain that indicates the organism's role in the flow of energy, such as producers, primary consumers, and secondary consumers.

Front

Give an example of a tertiary consumer.

Back

A tertiary consumer is an organism that eats secondary consumers; for example, a hawk that eats snakes.
