Food Webs and Ecosystems

Front

Define food webs and explain how they illustrate energy flow.

Back

Food webs show the complex interactions between organisms and how energy flows through an ecosystem from producers to consumers and decomposers.

Front

Differentiate between producers, consumers, and decomposers.

Back

Producers make their own food via photosynthesis, consumers eat other organisms, and decomposers break down dead matter.

Front

Identify trophic levels and describe the transfer of energy through ecosystems.

Back

Trophic levels include producers, primary consumers, secondary consumers, and tertiary consumers. Energy decreases at each level.

Front

Explain how disruptions in food webs can impact ecosystems.

Back

If a key species is removed, the balance of the ecosystem can be disrupted, leading to population increases or decreases.

Front

What is a Food Web?

Back

A network of interconnected food chains in an ecosystem.

Front

What is a Trophic Level?

Back

A step in the food chain or food web.

Front

What is an Energy Pyramid?

Back

A diagram showing the energy flow through each trophic level.

Front

What is an Ecosystem?

Back

A community of living organisms interacting with their physical environment.

Front

What is Biodiversity?

Back

The variety of life in a specific habitat or ecosystem.
