Ecosystem Interactions
| Question | Answer |
|---|---|
| Ecosystem | All the living and non-living things and all their interactions in an area. |
| Living | Characterized by having a metabolism and the ability to maintain life processes. |
| Nonliving | A part of the ecosystem that lacks the ability to grow, move, or respond to stimuli, and does not require energy to continue to exist, such as sunlight, air, water, rocks, and soil. |
| Organism | An individual living thing that can react to stimuli, reproduce, grow, and maintain life processes. |
| Adaptation | An inherited characteristic that provides a specific advantage to individuals that have it and becomes more common or pronounced in a population because of the advantage that it provides. |
| Producer | An organism that uses sunlight to make its own food for energy. |
| Consumer | An organism that gets energy by eating other organisms. |
| Carnivore | An animal that gets energy by only eating other animals. |
| Herbivore | An animal that gets energy by only eating plants. |
| Omnivore | An animal that gets energy by eating both plants and animals. |
| Symbiotic | A long-term relationship between two different kinds of organisms where one or both receive benefit. |
| Decomposer | An organism that consumes dead or nonliving biomass without need for internal digestion. |
| Food chain | The sequence of the transfer of food energy from one organism to another in an ecological community. |
| Food web | The entirety of interrelated food chains in an ecological community. |
| Energy transfer | The movement of energy from one item or species to another |
| Ecosystem | All of the living and non-living things and all of their interactions in an area. |
| Biome | A major ecological community of organisms adapted to a particular climatic or environmental condition on a large geographic area in which they occur. |
| Environment | The complex of physical, chemical, and biotic factors that act upon an organism or an ecological community and ultimately determine its form and survival. |
| Habitat | Place where an organism normally lives or occurs. |
| Scavenger | An organism that mostly consumes decaying biomass, such as meat or rotting plant material. |
| Predator | An animal that hunts and feeds upon other animals. |
| Prey | An animal that is hunted and eaten by other animals |
| Hibernation | A state of inactivity and slowed metabolic rates in animals |
| Migration | The relatively long-distance movement of individuals, usually on a seasonal basis. |
| Camouflage | An adaptation that allows animals to blend in with certain aspects of their environment increasing an organism's chance of survival. |
| limiting factor | An environmental factor that tends to limit population size. |
| Abiotic factor | Non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems. |
| Biotic factor | A living thing, as an animal or plant, that influences or affects an ecosystem: |
| Niche | The role or function of an organism or species in an ecosystem. |
| Population | Groups of individuals belonging to the same species that live in a shared region at the same time. |
| Community | An interacting group of various species in a common location. |
