|
Species |
A group of organisms consisting of similar individuals |
|
|
Population |
The number of individuals of the same specie living in an area. |
|
|
Community |
Different species living together in an area |
|
|
Ecosystem |
Different species living together in an area with their abiotic factors |
|
|
Biosphere |
The part of Earth that contains all ecosystems |
|
|
Biotic Factors |
Living factors that an affect an ecosystem Ex: Immigration, Emigration, Birth Rate |
|
|
Abiotic Factors |
Non-living factors that affect an ecosystem Ex: Water, Sun, Rocks |
|
|
Ecological Niche |
The full range of physical and biological conditions in which an organism lives and the way in which it uses those conditions |
|
|
Niche vs. Habitat |
Niche is a the conditions an organism lives in and how it uses those conditions Habitat is the environment an organism lives in |
|
|
Predation |
Is when a predator eats a prey for food Ex: Lion to Buffalo |
|
|
Competition |
Is when two different species compete for the same resource in the ecosystem |
|
|
Symbiosis |
Is when two different species have long-lasting physical contact, and one specie always benefits |
|
|
Symbiosis - Mutualism |
An interaction in which two different species in which both species benefit Ex: Rhino to Birds |
|
|
Symbiosis - Commensalism |
An interaction between two different species in which one specie benefits and other isn't affected Ex: Tree to Birds |
|
|
Symbiosis - Parasitism |
An interaction between two species in which one species benefits and the other loses Ex: Tick to Human |
|
|
Competitive Exclusion Principle |
Two species cannot occupy the same niche in the same habitat at the same time |
|
|
Photosynthesis vs. Chemosynthesis |
Photosynthesis is when an organism creates its own energy using solar energy Chemosynthesis is when an organism creates its own energy using chemicals |
|
|
Autotroph |
Photosynthetic organisms |
|
|
Heterotroph |
Organisms that can not photosynthesize and have to eat for energy |
|
|
Herbivores |
Organisms that only eat producers |
|
|
Carnivores |
Organisms that get food by only eating other consumers |
|
|
Omnivores |
Organisms that eat both producers and consumers for food |
|
|
10% Rule |
All trophic levels reduce energy by 90% the higher they get Ex: 100% PP - 10% PC - 1% SC - 0.1% TC |
