What is the carrying capacity of an ecosystem?

Back

The carrying capacity is the maximum number of individuals of a particular species that an environment can support sustainably.

Front

What is the primary source of energy for crickets?

Back

Crickets primarily get their energy from plants, such as cattails.

Front

How much energy is typically transferred from one trophic level to the next?

Back

Typically, only about 10% of the energy is transferred from one trophic level to the next.

Front

What is a producer in an ecosystem?

Back

A producer is an organism that can make its own food, serving as a source of energy for other organisms in the food chain.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web, representing the flow of energy and nutrients.

Front

What does a graph's carrying capacity point indicate?

Back

The carrying capacity point on a graph indicates the maximum population size that the environment can sustain.

Front

What is the role of herbivores in an ecosystem?

Back

Herbivores are primary consumers that eat producers and convert plant energy into a form that can be consumed by higher trophic levels.

Front

What is the difference between a food chain and a food web?

Back

A food chain is a linear sequence of organisms through which nutrients and energy pass, while a food web is a complex network of interconnected food chains.
