Ecology Unit

Study of living things and their interactions with the environment

Ecology The study of how living things interact with one another and with the non-living things in their environment.
Ecosystem A community of living organisms (plants, animals and microbes) in conjunction with the nonliving components of their environment (things like air, water and mineral soil), interacting as a system.
Abiotic Factors Non living things in the ecosystem ( air, water, rocks and soil, sunlight)
Biotic Factors Living things in the ecosystem (plants, animals and microbes)
Population A group of individuals of the same species that live in the same place.
Species Organisms that are the same species are closely related and can mate to produce offspring.
Community All the different species that live and interact in an area.
Habitat The place where an organism usually lives.
Producers Organisms that make their own food
Consumers Organisms that obtain and eat their food
Decomposers Organisms that a consumer that eats waste material
Symbiotic Relationships A close, prolonged association between two or more different organisms of different species that may, but does not necessarily, benefit each member.
Parasitism A symbiotic relationship where one species benefits and the other is harmed.
Mutualism A symbiotic relationship where both species benefit.
Commensalism A symbiotic relationship where one species benefits and the other is not helped or harmed.
Global change Changes to the planet's environmental systems, such as nutrients and water cycles, the climate, and ecosystems. Global change is frequently.
Nutrient pollution unintended inputs of nutrients, such as nitrogen and phosphorous, into natural areas. Often caused by agricultural fertilizers, human and livestock waste and by-products of industry.
Invasive Species Species that are introduced from their native range into a new area, where they then have an ecological or economic impact.
Endangered species A species of animal or plant that is seriously at risk of extinction.
Threatened species Threatened species are any species (including animals, plants, fungi, etc.) which are vulnerable to endangerment in the near future.
Endemic species An organism that is known to exist only in a certain location or region and is not naturally found anywhere else on the planet.
Niche An organisms special role in the ecosystem summary.
