Ecology

Population
A group of populations, living and interacting in the same area
Community
A group of ecosystem classified by climate and plant life
Biome
The nonliving physical and chemical conditions affecting organisms
Antibiotic factors
An association of living organisms and their physical environment
Ecosystem
The sum of all of earths ecosystems in land, water, or air
Biosphere
Organism that produce their own food
Producers

Decomposers

Habitat
Evaporation of water from the leaves of a plant
Transpiration
A close relationship between two or more species were at least one benefits
Symbiosis
A symbiotic relationship between two organisms of different species where all benefit from an association
Mutation
An organisms role in its ecosystem, including its habitat, physical requirements, the time of day it is active, it’s placed in the foodchain, and when and how it produces
Niche
A symbiotic relationship between two organisms of different species were one benefit, and the other is neither harm nor benefited
Commensalism
A symbiotic relation between two organisms of different species where one benefit and the other is harmed
Parasitism
The process of which certain gases trap heat that would otherwise escape the earth and radiate into space
Greenhouse effect
an organism that eats producers
Primary consumer
population growth that is unhindered because of the abundance of resources of an ever increasing population
Exponential growth
Population growth that is controlled by limited resources or the presence of predators or both
Logistic growth
