B-LS4-2 Evolution Results From Four Factors

Front

What is speciation?

Back

Speciation is the process by which new species arise from existing species, often due to factors like geographic isolation or environmental changes.

Front

What is geographic isolation?

Back

Geographic isolation occurs when a population of organisms is separated by physical barriers, such as mountains or rivers, preventing them from interbreeding.

What are selection pressures?

Back

Selection pressures are environmental factors that influence which individuals in a population are more likely to survive and reproduce.

What is competition in ecology?

Back

Competition is the interaction between organisms or species in which both are harmed as they vie for limited resources such as food, space, or mates.

Front

What are limiting factors?

Back

Limiting factors are environmental conditions that restrict the growth, abundance, or distribution of a population, such as food availability, predation, and disease.

What is natural selection?

Back

Natural selection is the process by which organisms that are better adapted to their environment tend to survive and produce more offspring.

How does population density affect competition?

Back

As population density increases, competition for resources also increases, leading to potential stress on the population.

Front

What is the relationship between population growth and limiting factors?

Back

Population growth cannot continue indefinitely due to limiting factors that restrict resources and space.

Front

What is the difference between interspecific and intraspecific competition?

Back

Interspecific competition occurs between different species, while intraspecific competition occurs within the same species.

Front

What is the role of adaptation in evolution?

Back

Adaptation is a trait that enhances an organism's ability to survive and reproduce in its environment, contributing to evolutionary change.
