- Ecology
- The study of the interaction between organisms and their enviornment
- Biotic
-
The part of the enviornnment is all organism that live together and interact with one another
Living - Abiotic
-
the part of the enviornment that includes all the physical features.
Non-living - Population
- a group of individual of the same species that live together in the same area at the same time.
- Community
- consists of all of the populations of different species that live and interact in an area
- Ecosystems
- made up of a community of organisms and its abiotic enviornment.
- Biosphere
- part of the world where life exist
- Herbivore
- a consumer that eats plants
- Carnivore
- a consumer that eats animals
- Omnivore
- eat a variety of organisms, both plants and animals
- Scavengers
- animals that feed on bodies of dead animals
- Food Chains
- represents how the energy in food molecules flow from one organism to the next.
- Food Web
- Many different food chains within and ecosystem
- Energy Pyramid
- the amount of available energy is reduced at a higher level because most of energy is either used by the organism or given off as heat.
- Habitat
- an organisms enviornment in which it lives
- Niche
- an organism's niche includes its habitat, its food, its preditors, and the organisms with which it competes
- Carrying Capacity
- When a population grows larger than its carrying capacity
- Prey
- The organism that is eaten
- Predator
- The organism that eats the prey
- Symbiosis
- a close, long-term association between two or more species
- Mutualism
- A symbiotic relationship in which both organism benefit
- Commensalism
- A symbiotic relationship in which one organism benefits and other is unaffected
- Parasitism
- The organism that benefits
- Coevolution
- A long-term change that takes place in two species because of their close interaction with one another
- Precipitation
-
When water moves from the atmosphere to the land and oceans.
This process includes rain, snow, sleet, and hail. - Evaporation
- The sun's heat causes water to change from liquid to vapor
- Ground Water
-
This type of water may stay in the ground for hundreds or even thousands of years
Ground water provides water to the soil, stream, rivers, and oceans - Decompoition
- The breakdown of dead material into carbon dioxide and water
- Combustion
- The carbon in coal, oil, and natural gas returns to the atmosphere as carbon dioxide
