Carrying Capacity Flashcards
carrying capacity
Largest number of individuals of a population that a environment can support without degrading
Limiting factor
An environmental factor that prevents a population from increasing
Density dependent
Factors that have a higher impact as the population density increases.
Density independent
Factors that impact a population regardless of the population density.
Population
A group of individuals that belong to the same species and live in the same area
Ecosystem
A biological community of interacting organisms and their physical environment.
Population Density
Number of individuals per unit area
Competition
orgranisms struggle against one another to obtain what they need to survive
Density Dependent Examples
Food, Shelter, Space, Water, Disease, Nutrient levels,
Abiotic factor
Any nonliving part of the ecosystem, such as water, minerals, sunlight, air, or soil
Biotic factor
Any living thing that is part of an ecosystem
Density Independent Examples
Tornado, Flood, Natural disasters, Laws, Habitat disruption
Logistic Growth
Population growth that is controlled by limited resources, where the graph creates an S shape as it levels off.
Exponential Growth
growth of a population that multiplies by a constant factor at constant time intervals, resulting in an upward spike over time.
Predation
An interaction in which one organism captures and feeds on another organism
