Limits to growth Flashcards
Limiting Factors on Population Density
Competition
When competing for resources
Limiting Factor
Controls growth of a population either biotic or abiotic environmental factors that affect members of a population this determines the carrying capacity.
Density-Dependent Limiting Factors
Families or groups of populations having factors that limit the group such as competition and overcrowding
Parasitism and disease
(Negative impact on populations and a limiting factor)
Weakens host and spreads disease in big populations
Stress from Overcrowding
(Negative impact on populations and a limiting factor)
Leads to fights among species, stress related health issues
Predation and Herbivory
(Negative impact on populations and a limiting factor)
Effects of predators on prey and herbivores on plants
Density-Independent Limiting Factors
Impacts the whole population regardless size or density like extreme weather
Population CRASH
when population reaches limit sudden decline to one of these factors
