Ecology concept 1/2
what is ecology
Ecology is the study of relationships bettwen two organisms.
What is a population
A group of organisms of the same species living in the same place.
What is Sustainability
A balance between Earth’s resources, human needs, and the needs of other species.
Two types of succession
Primary succession: formation of a brand new
ecosystem.
Secondary succession: recovery of an old
ecosystem.
What is Competition
A relationship that exists between two or more organisms that are fighting for the same limited resource.
What is Biodiversty
Variety of all Earth's life.
What are limiting factors
Aspects of the environment that limit the size a population can reach.
What is a Ecological (Carbon) Footprint
The amount of carbon emitted and its environmental impact.
Pioneer Species means
the first organisms to grow in
a new environment.
What are keystone species.
A species that holds the the ecosystem together; it is critical for the survival of the other species in the ecosystem.
What are the Biogeochemical cycles
Water cycle
Carbon cycle
Nitrogen cycle
What are the 3 types of Survivorship Curves
Type 1:Late loss
Type 2:Constant loss
Type 3:Early loss

when dose Primary succession occurs
Primary succession occurs when a
community forms in an area that has not been
previously occupied.
What is Symbiosis
A) No Species benifit
B)One Species benifit
C)Both Species benifit

A biotic is anything...
What are Density-independent limiting factors
They regulate population growth regardless of its
size or density.
What are the Greenhouse gases
CO2, O2, CH4, H2O
what happens Once enough soil has been generated to
retain nutrients.
small plants, flowers, ferns,
and shrubs can begin to grow.
