Changes in populations

Front

What are limiting factors in an ecosystem?

Back

Limiting factors are conditions that prevent a population from growing too large, such as food availability, water supply, and space.

Front

How do predator and prey populations affect each other?

Back

Predator populations decrease when prey populations are low because predators run out of food.

Front

What is the flow of energy in a food chain?

Back

Energy flows from producers (like grass) to primary consumers (like rabbits) and then to secondary consumers (like coyotes).

Front

What does biodiversity mean?

Back

Biodiversity refers to the variety of different species of plants and animals in a particular area.

Front

What can cause an increase in a rabbit population?

Back

An increase in rain can lead to more grass growth, providing more food for rabbits.

Front

What is a food web?

Back

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

Front

What is the role of producers in an ecosystem?

Back

Producers, like plants, create energy through photosynthesis and are the foundation of the food chain.

Front

What happens when a new predator is introduced to an ecosystem?

Back

The introduction of a new predator can decrease the population of prey species, affecting the entire food web.

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 does pollution affect ecosystems?

Back

Pollution can harm organisms, reduce biodiversity, and disrupt food chains and webs.
