| Term | Definition |
|---|---|
| Ecosystem | A community of organisms, their physical environment, and the interaction that happens between them. |
| Community | All of the populations of different species that live in the same area and interact with one another. |
| Population | A group of individuals of the same species living in one area at one time. |
| Symbiosis | An interspecific interaction in which the different species live together in a long term relationship. |
| Disease | an abnormal condition of an organism which interrupts the normal bodily functions |
| Pathogen | biological agents that cause disease (some are living, some are non-living) |
| Sign | can be detected (seen) or measured by another individual |
| Symptom | is experienced or felt by the individual affected by the disease |
| Prevention | inhibiting the introduction of a disease into an area, population or individual |
| Treatment | the use of an agent or procedure (such as a drug or surgery) in an attempt to cure or mitigate a disease condition |
| Epidemic | the occurrence of more cases of a disease than would be expected in a community, country or region during a given period |
| Pandemic | an epidemic of a disease that has spread across a large region (e.g. multiple continents or worldwide) |
| Vaccination | treatment with a vaccine (a substance that contain a weakened or dead pathogen which is injected in order to stimulate the immune response) to produce immunity to a particular infectious disease or pathogen |
| Ecology | the study of the relationships between living things and their environment. |
| Environment | all of the living and non living factors that affect the survival of an organism in its living place. |
| Habitat | the living place of an organism |
| Biodiversity | the total variety of organisms, habitats, communities and ecological processes |
| Predator | an organism that consume other organisms (prey) that they actively hunt |
| Producer | organisms that make their own energy-rich molecules (e.g. glucose) by using the Sun’s energy to convert simple molecules into larger energy-rich molecules |
| Consumer | organisms that get their energy from the food they eat |
| Decomposer | organisms that break down energy rich molecules (e.g. glucose) in dead organisms and the wastes of organisms into simple molecules and so help to recycle matter. |
| adaptation | A feature that enhances an organism’s chance of survival. |
