Ecology Unit
Study of living things and their interactions with the environment
| Term | Definition |
|---|---|
| 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. |
