What is a food web?

Back

A food web is a complex network of feeding relationships among organisms in an ecosystem, showing how energy flows through various interconnected food chains.

Front

What is a food chain?

Back

A food chain is a linear sequence that shows how energy and nutrients flow from one organism to another in an ecosystem, typically starting with a producer and ending with a top predator.

Front

What role do producers play in a food web?

Back

Producers, such as plants and algae, convert sunlight into energy through photosynthesis and form the base of the food web.

Front

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

Back

A food chain is a single, linear pathway of energy flow, while a food web is a complex network of multiple interconnected food chains.

Front

What is the significance of decomposers in a food web?

Back

Decomposers break down dead organic matter, recycling nutrients back into the ecosystem and supporting the growth of producers.

Front

How does energy flow through a food web?

Back

Energy flows from producers to primary consumers, then to secondary consumers, and so on, with energy decreasing at each trophic level due to metabolic processes.

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 producer, primary consumer, or secondary consumer.

Front

What is an example of a primary consumer?

Back

An example of a primary consumer is a herbivore, such as a rabbit, that eats plants.

Front

What is an apex predator?

Back

An apex predator is a top predator in a food web that has no natural enemies and plays a crucial role in maintaining the balance of the ecosystem.

Front

How do food webs demonstrate ecosystem stability?

Back

Food webs demonstrate ecosystem stability by showing how multiple feeding relationships can provide resilience against changes, such as the loss of a single species.
