CHAPTER 4: THE ORGANIZATION OF LIFE
VOCABULARY LIST
DEFINE THE FOLLOWING TERMS FROM THE GLOSSARY:
ECOSYSTEM: a community of organisms and their abiotic environment.
BIOTIC FACTOR: an environmental factor that is associated with or results from the activities of living organisms (100)
ABIOTIC FACTOR: describes the non-living part of the environment, including water, rocks, light, and temperature.
ORGANISM: a living; anything that can carry out life processes independently.
SPECIES: a group of organisms that are closely related and can mate to produce fertile offspring; also the level of classification below genus and above sub-species.
POPULATION: a group of organisms of the same species that live in a specific geographical area and interbreed.
COMMUNITY: a group of various species that live in the same habitat and interact with each other.
HABITAT: the place where an organism usually lives.
NATURAL SELECTION: the process by which individuals that are better adapted to their environment survive and reproduce more successfully than less well adapted individuals do; a theory to explain the mechanism of evolution.
EVOLUTION: a heritable change in the characteristics within a population from one generation to the next; the development of new types of organisms from preexisting types of organisms over time.
ADAPTATION: the process of becoming adapted to an environment; an anatomical, physiological, or behavioral change that improves a population’s ability to survive.
ARTIFICIAL SELECTION: the selective breeding of organisms (by humans) for specific desirable characteristics.
RESISTANCE: in biology, the ability of an organism to tolerate a chemical or disease-causing agent.
ARCHEABACTERIA: a kingdom made up of prokaryotes (most of which are known to live in extreme environments) that are distinguished from other
