Population Flashcards
Population
In the number of given Individuals in a given area or volume
Carrying capacity
The maximum amount of organisms in a population that can survive on the availabke resources
Interspecific competition
Competition Among different species
Ex leopard/lions over gazelle
Infraspecific competition
Competition among the same species
Ex: wolves over deer.
Density dependent factors
This variables that affect a population based on the degree crowding.
Ex disease
Stress
Competition
Predation
Density independent factors
Variables that affect a population regardless of the crowding.
Ex: weather Fire Frost Animal feeders Urban development Lightning Deforestation
What are the 4 factors that determine a populations carrying capacity
Materials and energy: limited by amount of usable sun,water and carbon
Food chains: limited by food supply
Competition: the demand for resources bring competition.
Density: different species have different needs for space.
