|---|---|
| Organism | Living things |
| Habitat | An environment that provides the things a specific organism needs to live,grow,and reproduce |
| Biotic factor | The parts of a habitat that are or were once alive. |
| Abiotic factor | Non-living parts of an organism’s habitat. |
| Species | A group of organisms that can mate with each other and produce offspring that can also mate and reproduce. |
| Population | All members of one species living in a particular area. |
| Community | All the different populations that live together. |
| Ecosystem | The community of organisms that lives in a particular area,along with the non living environment. |
| Ecology | The study of how organisms interact with each other and with their environment. |
| Producer | An organism that can make its own food |
| Consumer | Obtains energy by feeding on others organisms |
| Decomposer | Breaks down biotic wastes and dead organisms |
| Food chain | A series of events in which one organism eats another and obtains energy |
| Limiting factor | A population to stop growing or to decrease in size, such as a fatal disease infecting organisms |
| Carnivores | Consumers that only eat animals |
| Herbivores | Consumers that eat only plants |
| Omnivores | Consumers that eat both plants and animals |
| Parasitism | A relationship that involves one organism with,on,or inside another organism and harming it |
| Mutualism | a relationship in which both species benefit |
| Commensalism | a relationship in which one species benefits and other species is neither helped nor normal |
| Symbiosis | Any relationship in which two species live closely together |
| Predation | An interactions in which one organisms kills another for food or nutrition |
| Competition | When two species share a niche,one of their populations might be effected |
| Interaction | Takes place among organisms every day |
| Chlorophyll | Absorbs light, much like cells in solar panels do |
| Photosynthesis | A set of chemical reactions plants use to turn light, water, and nutrients into oxygen and energy, in the form of sugars |
| Energy pyramid | Shows the amount of energy that moves from one feeding level to another in a food web |
| Carrying capacity | The largest population that an area can support |
| Population density | The number of individuals in an area of a specific size |
| Predation | An interactions in which one organisms kills another for food or nutrition |
| Food web | Consists of many overlapping food chains in an ecosystem |
