Food Webs and Food Chains II

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, starting from producers to various levels of consumers.

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains in an ecosystem, illustrating how different organisms are related through feeding relationships.

Front

What role do producers play in a food chain?

Back

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

Front

What are primary consumers?

Back

Primary consumers are herbivores that eat producers. They are the second level in a food chain.

Front

What are secondary consumers?

Back

Secondary consumers are carnivores that eat primary consumers. They are the third level in a food chain.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web, defined by how an organism obtains its energy.

Front

What happens if a top predator is removed from an ecosystem?

Back

If a top predator is removed, it can lead to an overpopulation of primary consumers, which may result in overgrazing and depletion of producers.

Front

How do decomposers fit into a food web?

Back

Decomposers break down dead organic matter, returning nutrients to the soil and making them available for producers.

Front

What is the significance of biodiversity in food webs?

Back

Biodiversity increases the resilience of food webs, allowing ecosystems to better withstand changes and disturbances.

What is an example of a food chain?

Back

Grass -> Grasshopper -> Frog -> Snake -> Hawk.
