3. Chapter 4 Vocabulary
Ecosystem- a community of organisms and their abiotic environment.
Community- a group of various species that live in the same habitat and interact with each other.
Biotic factor- an environmental factor that is associated with or results from the activities of living organisms.
Habitat- the place where an organism usually lives.
Abiotic factor- the nonliving part of the environment, including water, rocks, light, and temperature.
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.
Organism- a living thing: 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.
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.
Population-a group of organisms of the same species that live in a specific geographical area and interbreed.

4. Chapter 4 Vocabulary continued
Adaptation-an anatomical, physiological, or behavioral change that improves a population’s ability to survive.
Fungus- an organism whose cells have nuclei (eukaryotic), rigid cell walls, and no chlorophyll and that belong to the kingdom Fungi.
Protist- an organism that is typically single celled, eukaryotic and found in water.
Artificial selection- the selective breeding of organisms (by humans) for specific desirable characteristics.
Gymnosperm- a woody vascular seed plant, whose seeds are not enclosed by an ovary or fruit.
Resistance- the ability of an organism to tolerate a chemical or disease-causing agent.
Angiosperm- a flowering plant that produces seeds within a fruit.
Archaebacteria- a kingdom made up of prokaryotes, most of which are known to live in extreme environments.
Invertebrate- an animal that does not have a backbone.
Eubacteria- a kingdom made up of all prokaryotes, true bacteria with a cell wall of peptidoglycan.
Vertebrate- an animal that has a backbone: includes mammals, birds, reptiles, amphibians, and fish.
