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 primary producers to various levels of consumers.

Front

What is a Food Web?

Back

A Food Web is a complex network of interconnected food chains that illustrates the feeding relationships among various organisms in an ecosystem.

Front

What are Trophic Levels?

Back

Trophic Levels are the different levels in a food chain or food web, representing the flow of energy and nutrients from producers to various levels of consumers.

What is Biomass?

Back

Biomass refers to the total mass of living matter within a given area or volume, often measured in terms of weight per unit area.

Front

What is the Pyramid of Energy?

Back

The Pyramid of Energy is a graphical representation that shows the flow of energy at each trophic level in an ecosystem, illustrating that energy decreases as it moves up the pyramid.

What is the Pyramid of Biomass?

Back

The Pyramid of Biomass is a graphical representation that shows the total biomass at each trophic level in an ecosystem, indicating the amount of living tissue available.

Front

What is the Pyramid of Numbers?

Back

The Pyramid of Numbers is a graphical representation that shows the number of individual organisms at each trophic level in an ecosystem.

Front

What is the role of Primary Producers?

Back

Primary Producers are organisms, such as plants and algae, that produce their own food through photosynthesis and form the base of the food chain.

Front

What is the role of Primary Consumers?

Back

Primary Consumers are herbivores that eat primary producers and are the second trophic level in a food chain.

Front

What is the role of Secondary Consumers?

Back

Secondary Consumers are carnivores or omnivores that eat primary consumers and are the third trophic level in a food chain.
