100
The process by which individuals that have favorable variations and are better adapted to their environment survive and reproduce more successfully than less well adapted individuals do
What is natural selection?
200
The process of becoming suited to an environment; an anatomical, physiological, or behavioral change that improves a population's ability to survive
What is an adaptation?
200
A collection of similar ecosystems named after the dominant plant life.
What is a biome?
200
An organism whose cells have nuclei, rigid cell walls, and no chlorophyll and are all heterotrophic, most decomposers, but some parasites
What is a fungus?
200
A multicellular, heterotrophic organism that usually has sense organs and a nervous system
What is an animal?
200
A change in the characteristics of a population from one generation to the next; the gradual development of organisms from other organisms since the beginnings of life
What is evolution?

An environmental factor that is associated with or results from the activities of living organisms
What is a biotic factor?
300
A living thing; anything that can carry out life processes independently
What is an organism?
300
