5.9B Food Webs

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains in an ecosystem, showing how energy and nutrients flow between different organisms.

Front

What is a producer in a food web?

Back

A producer is an organism that can make its own food using sunlight, water, and carbon dioxide, typically through photosynthesis. Examples include plants and algae.

Front

What is a consumer in a food web?

Back

A consumer is an organism that cannot produce its own food and must eat other organisms (plants or animals) to obtain energy. Examples include animals like deer and squirrels.

Front

What is a decomposer?

Back

A decomposer is an organism that breaks down dead or decaying organisms, returning nutrients to the soil. Examples include fungi and bacteria.

Front

How does energy flow in a food web?

Back

Energy flows from producers to consumers and then to decomposers, typically represented by arrows pointing from one organism to another.

Front

What role do plants play in a food web?

Back

Plants act as producers, converting sunlight into energy through photosynthesis, which supports the entire food web.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers recycle nutrients back into the soil, making them available for producers, and help break down dead matter.

Front

What is the significance of arrows in a food web diagram?

Back

Arrows in a food web diagram indicate the direction of energy flow from one organism to another.

Front

Can you give an example of a food chain?

Back

An example of a food chain is: Grass (producer) → Grasshopper (primary consumer) → Frog (secondary consumer) → Snake (tertiary consumer).

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 multiple food chains.
