Unit 4 invasive species and evolution review

Front

What is selective breeding?

Back

Selective breeding is a method used by humans to breed plants and animals for specific traits by choosing parents with desired characteristics.

Front

How does selective breeding help horse breeders?

Back

Selective breeding helps breeders control which traits are passed on by producing horse offspring that only have the desired traits.

Front

What is natural selection?

Back

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is an invasive species?

Back

An invasive species is a non-native organism that spreads rapidly in a new environment, often causing harm to native species and ecosystems.

Front

How do invasive species affect native species?

Back

Invasive species can outcompete native species for resources, leading to a decrease in native populations.

Front

What is competition in ecology?

Back

Competition occurs when two or more species or individuals vie for the same resources, such as food, space, or light.

Front

What is the impact of invasive species on ecosystems?

Back

Invasive species can disrupt ecosystems by altering food webs, reducing biodiversity, and changing habitat structures.

Front

Why do invasive species grow quickly in new environments?

Back

Invasive species often grow quickly because they have no natural predators in the new environment.

Front

What is the difference between natural selection and artificial selection?

Back

Natural selection is driven by environmental pressures, while artificial selection is driven by human choices.

Front

What is extinction?

Back

Extinction is the end of an organism or a group of organisms, typically due to environmental changes or loss of habitat.
