Mini Review: Populations and Resources

Front

What is a population in an ecosystem?

Back

A population is a group of individuals of the same species living in a specific area at the same time.

Front

What factors can affect the size of a population?

Back

Factors include birth rates, death rates, immigration, and emigration.

Front

What is carrying capacity?

Back

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

Front

How do predators affect prey populations?

Back

Predators can decrease prey populations by hunting them, which can lead to a balance in the ecosystem.

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among organisms in an ecosystem.

Front

What happens when a predator population increases?

Back

An increase in predator population can lead to a decrease in prey population due to increased predation.

Front

What is the role of producers in an ecosystem?

Back

Producers, like plants, create energy through photosynthesis and form the base of the food chain.

Front

What is the difference between immigration and emigration?

Back

Immigration is the arrival of individuals into a population, while emigration is the departure of individuals from a population.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web, defined by how an organism obtains its energy.

Front

What is the significance of energy transfer in ecosystems?

Back

Energy transfer is crucial for maintaining the balance of ecosystems, as energy flows from producers to consumers.
