Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web that indicates the flow of energy and nutrients through an ecosystem, typically categorized as producers, primary consumers, secondary consumers, and tertiary consumers.

Front

How many trophic levels are typically found in a food web?

Back

Food webs can have multiple trophic levels, commonly ranging from 2 to 5, depending on the complexity of the ecosystem.

Front

What are the products of cellular respiration?

Back

The products of cellular respiration are carbon dioxide and water.

Front

What does the arrow in a food web represent?

Back

The arrow in a food web represents the flow of energy from one organism to another.

Front

What is a producer in an ecosystem?

Back

A producer is an organism that can make its own food through photosynthesis or chemosynthesis, serving as the base of the food web.

Front

What is a primary consumer?

Back

A primary consumer is an organism that eats producers; they are typically herbivores.

Front

What is a secondary consumer?

A secondary consumer is an organism that eats primary consumers; they can be carnivores or omnivores.

Front

What is a tertiary consumer?

Back

A tertiary consumer is an organism that eats secondary consumers, often at the top of the food chain.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, producing carbon dioxide and water as byproducts.

Front

How is energy transferred in a food web?

Back

Energy is transferred in a food web through consumption, where each trophic level receives energy from the level below it.
