Study Notes

Organism and Habitat

  • An organism is a living thing.
  • A habitat is an environment that provides the necessary things for an organism to live, grow, and reproduce.

Biotic and Abiotic Factors

  • Biotic factors are the parts of a habitat that are or were once alive and interact with an organism.
  • Abiotic factors are the nonliving parts of an organism's habitat.

Population, Community, and Ecosystem

  • A population is all the members of one species living in a particular area.
  • A community is all the different populations that live together in an area.
  • An ecosystem is the community of organisms that live in a particular area, along with the nonliving environment.

Limiting Factors and Resources

  • A limiting factor is an environmental factor that causes a population to stop growing or to decrease in size.
  • A resource is the food, water, shelter, and other things that an organism gets from its environment to live, grow, and reproduce.

Population Density

  • Population density is the number of individuals in an area of a specific size.
