Limiting Factors
This flashcard set explores the biotic and abiotic limiting factors that affect population size, distribution, and reproduction within ecosystems. It distinguishes between density-dependent factors (like disease, food supply, and predation) and density-independent factors (such as weather and habitat disruption).
Limiting Factors
biotic or abiotic factors that control the number, distribution, or reproduction of a population within a community
Key Terms
Limiting Factors
biotic or abiotic factors that control the number, distribution, or reproduction of a population within a community
Density Dependent
environmental factor such as predation, disease, and competition that depends on the number of members in a population per unit area
Density Independent
environmental factor such as storms or extreme hot or cold that affects population regardless of their density
Disease
A density dependent factor in which the body is not functioning normally
food supply
Density dependent factor, if this is in short supply then are many organisms that will fight over it
predation
Density dependent factor in which one organism kills another for food

Density Independent | environmental factor such as storms or extreme hot or cold that affects population regardless of their density |
Disease | A density dependent factor in which the body is not functioning normally |
food supply | Density dependent factor, if this is in short supply then are many organisms that will fight over it |
predation | Density dependent factor in which one organism kills another for food |
habitat disruption | Density independent factor where an animal's living space has been disturbed or destroyed and must now find a new place to live |
Invasive species | Density Dependent non native species that moves into an environment and has an impact by taking away resources |
Competition | Dependent factor in which organisms must fight for resources such as food, water, and shelter |
Carrying capacity | Largest number of individuals of a population that a environment can support |
Exponential growth | type of growth that is extremely rapid and occurs when there are no limiting factors |
Logistic growth | Type of growth in which a population experiences rapid growth then settles around carrying capacity due to limiting factors |
Population | A group of the same species that live in the same area |
Ecosystem | All the living and nonliving things in an area that interact |
Abiotic Factors | nonliving parts of an ecosystem |
Biotic Factors | living parts of an ecosystem |
population density | The number of individuals in an area of a specific size |
