Unit 10 Biodiversity

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the diversity of species, genetic variation, and ecosystem diversity.

Front

What is a common ancestor?

Back

A common ancestor is an organism from which different species have evolved. It is the most recent species from which two or more species have descended.

Front

What is natural selection?

Back

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

Front

What is environmental fitness?

Back

Environmental fitness is the ability of an organism to survive and reproduce in its environment.

Front

What is speciation?

Back

Speciation is the evolutionary process by which populations evolve to become distinct species.

Front

What role do offspring play in evolution?

Back

Offspring contribute to evolution by carrying genetic variations that may enhance survival and reproduction in changing environments.

Front

What is adaptation?

Back

Adaptation is a trait that helps an organism survive and reproduce in its environment.

Front

What is the significance of the Galapagos finches?

Back

The Galapagos finches are significant because they illustrate how species can evolve differently based on their environment and available resources.

Front

What is the relationship between population size and survival?

Back

Larger populations tend to have a higher probability of survival because they can produce more offspring, increasing the chances of some surviving.

Front

What is genetic variation?

Back

Genetic variation refers to the differences in DNA among individuals within a population, which can lead to different traits.
