Populations and Resources Review

Front

What is the relationship between energy storage molecules and reproduction in organisms?

Back

More energy storage molecules lead to more reproduction.

Front

What happens to a resource population when a consumer population increases in size?

Back

The resource population decreases.

Front

What is the impact of a decrease in energy storage molecules on the reproduction rate of a population?

Back

The reproduction rate will decrease.

Front

How do organisms in consumer populations obtain energy storage molecules?

Back

By eating organisms in resource populations.

Front

What effect does a larger resource population have on its consumer populations?

Back

It increases the energy storage molecules available.

Front

Define energy storage molecules.

Back

Molecules that store energy for use by organisms, such as carbohydrates and fats.

Front

What role do producers play in an ecosystem?

Back

Producers create energy storage molecules through photosynthesis.

Front

Explain the concept of carrying capacity.

Back

The maximum population size of a species that an environment can sustain indefinitely.

Front

What is the significance of energy flow in an ecosystem?

Back

Energy flow determines the structure and function of ecosystems.

Front

How does competition affect resource populations?

Back

Competition can lead to a decrease in resource populations as consumers exploit them.
