Energy Flow in Ecosystems

Front

What is energy flow in ecosystems?

Back

Energy flow in ecosystems refers to the transfer of energy from one trophic level to another, starting from producers to various levels of consumers and decomposers.

What is a producer in an ecosystem?

Back

Producers are organisms, like plants and algae, that can make their own food through photosynthesis, forming the base of the food chain.

Front

What is a primary consumer?

Back

Primary consumers are organisms that eat producers; they are typically herbivores that obtain energy by consuming plants.

Front

What is a secondary consumer?

Back

Secondary consumers are organisms that eat primary consumers; they can be carnivores or omnivores.

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.

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains that illustrates how different organisms are related through feeding relationships.

Front

What is an energy pyramid?

Back

An energy pyramid is a graphical representation that shows the flow of energy at different trophic levels in an ecosystem, with energy decreasing as you move up the pyramid.

Front

What are heterotrophs?

Back

Heterotrophs are organisms that cannot produce their own food and must consume other organisms for energy; they include all consumers.

Front

What are autotrophs?

Back

Autotrophs are organisms that can produce their own food from inorganic substances; they include producers like plants.

Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead and decaying organic matter, recycling nutrients back into the ecosystem and helping to maintain soil health.
