Ecology, Ecodynamics, And Ecosystems (7th) Flashcards
Hibernation
An adaptation for winter survival in which animals become in active and bodily functions slow down
Organic farming
Involves The use of natural fertilizers and pest controls
Migration
Seasonal movement of animals
Dormancy
State of being very quiet and appearing life-less
Deforestation
The complete removal of trees and other plants in an area
Eutrophication
Standing water becomes covered with algae, making it impossible for the top layer of water to mix with oxygen.
Erosion
The wearing away of land by water, wind, or ice
Drought
A period of unusually Low amount of precipitation
Flood
A period of unusually high amount of precipitation
Conservation
The careful use of the earth’s resources
Solar power
A clean and safe way of producing power using the sun’s energy
Limiting factors
Conditions that keep populations from increasing in size
Exotic species
Species that are not native to an area
Phototropism
The tendency of plants to grow towards the sun
Population
Organisms of one species living together in a particular area (habitat)
SSS- Same Species, same time
Community
Interacting populations living together in the same habitat
All different populations
Habitat
The place an organism lives in a community
Niche
The way a population finds three things to stay alive
1) food
2) living space
3) shelter
Succession
The gradual change of a community over time. (Grass to bushes to pines to hardwoods)
Pioneer species
The first plants to grow in an area. They create an area that helps other species to grow
Renewable resource
Resources that can be replaced
Non-renewable resources
Can’t be replaced (oil)
Conservation
The wise and careful use of our resources
Ecosystems
are all the living species in an are and the abiotic factors of that area
Fire
The burning of brushes and small plants to tall trees
What are three examples of human changes?
Deforestation, eutrophication, overpopulation
What are four examples of natural changes?
Flood, fire, drought, and erosion
Overpopulation
Too many people living in an area where the ecosystem can not hold
Leads to Urban Development/ urban sprawl in an area
What are the five levels or environmental organization?
Organism, population, community, ecosystem, and biosphere
Niche
The role of an organism within a community
