Ecology
|
Definition: The scientific study between living things and their enviornments.
Example:A scientist observing a forest. |
|
Enviorment
|
Definition:All living and nonliving things that surround an organism.
Example:The trees, rocks, and wildlife aroung a rabbit. |
|
Interact
|
Definition:Living and nonliving things acting on eachother.
Example:Grass grows and rabbits eat it. |
|
Physical Enviornment
|
Definition:Nonliving things in an enviornment.
Example:Water, Air, light, and climate. |
|
Biological Enviornment
|
Definition:Living things in an enviornment.
Example:Plants, trees, animals. |
|
Ecosystem
|
Definition:Made up of living and nonliving things in an enviornment that interact with eachother.
Example:Rabbits eat the grass. |
|
-Eco
|
Definition:Enviornment.
Example:Forest. |
|
-System
|
Definition:Set of parts that work together as a single unit.
Example:Populations |
|
Biosphere
|
Definition:Portion of Earth in which living things exist.
Example:Ocean. |
|
Organism
|
Definition:A complete living thing.
Example:Rabbits. |
|
Habitat
|
Definition:Place where an organism lives.
Example:Forest. |
|
Niche
|
Definition:The role each organism plays in its habitat.
Example: Rabbits eat grass and thier waste decomposes and puts nutrients back into the Earth. |
|
Population
|
Definition:A group of organisms of the same species that are found together at a given place and time.
Example:Rabbits. |
|
Community
|
Definition:All populations living together in an ecosystem.
Example:Rabbits, Foxes, Birds, Plants, etc. |
|
Zonation
|
Definition:Changes in communities due to changes in the structure of the landscape.
Example:Evolutuion due to the filling in of a pond. |
|
Succession
|
Definition:Process by which one community is replaced by another over time.
Example:Lichens to eventually Maple Trees. |
|
Climax Community
|
Definition:The final community that replaces a past one.
Example:Maple trees replace lichen. |
|
Food Chain
|
Definition:A model of the feeding relationships in an ecosystem.
Example:Scud eats algae, fish eats scud, bigger fish eats smaller fish. |
|
Producer
|
Definition:The start of the food chain, usually a plant that makes its own food.
Example:Algae. |
|
Primary Consumer
|
Definition:An organism that eats producers.
Example:Fish eats algae. |
|
Secondary Consumer
|
Definition:Organism that eats primary consumers.
Example:Big fish eats the small fish that ate the algae. |
|
Tertiary Consumer
|
Definition:Organism that eats secondary producers.
Example:A bigger fish eats the big fish that ate the little fish that ate the algae. |
|
Decomposer
|
Definition:Organisms that break down the remains or waste of other organisms.
Example:Bacteria or fungi. |
|
Enegy Pyramid
|
Definition:Model that shows how energy moves through a food chain.
Example:Sun gives energy to plants and plants are eaten by animals and they get the energy. |
|
Fod Web
|
Definition:A model that shows how all organisms are connected through eating each other.
Example:Foxes and Owls are connected because they both eat Chipmunks. |
|
Water Cycle
|
Definition:Cycle in which water is re-used.
Example:Water evaporates, condenses, andpercipitates down to begin again. |
|
Oxygen-Carbon Dioxide Cycle
|
Definition:Cycle in which O2 and CO2 is recycled.
Example:Plants exhale the oxygen that we breathe and we exhale the carbon dioxide that plants breathe. |
|
Nitrogen Cycle
|
Definition:Cycle in which nitrogen is recycled.
Example:Organisme dies and nitrogen goes into thew ground. Other organisms will the use the nitrogen for themselves until they die and the cycle is continued. |
|
Predator-Prey(+-)
|
Definition:Something(predator) eats something(prey) else.
Example:Is benefitial to predator but harmful to prey |
|
Parasitism(+-)
|
Definition:One organism attaches itself to another organism and leeches of it's food and life force.
Example:Tick attaches itself to a dog. |
|
Mutualism(++)
|
Definition:Two organisms live off of one another.
Example:Trees and fungi. |
|
Commenalism(+0)
|
Definition:One grows on another.
Example:Vines grow on trees. |
