Environmental resistance factors are things that limit the growth of a population. They include biotic factors – like predators, disease, competition, and lack of food – as well as abiotic factors – like fire, flood, and drought. The biotic potential of a population is how well a species is able to survive.
What is an environmental resistance?
Definition of environmental resistance
: the sum of the environmental factors (such as drought, mineral deficiencies, and competition) that tend to restrict the biotic potential of an organism or kind of organism and impose a limit on numerical increase.
Which of the following are examples of environmental resistance quizlet?
Environmental resistance is environmental factors such as: droughts and competitions. It can restrict the biotic potential of organisms and not let them increase. Droughts and competition can both cause death thus decreasing the population of the organisms.
What is the effect environmental resistance of a population?
Environmental Resistance can reduce the reproductive rate and average life span and increase the death rate of young. • As Environmental Resistance increases, population growth slows and eventually stops, likely near (k).
Is carrying capacity and environmental resistance?
Environmental resistance are factors that limit the biotic potential of an organism. It includes abiotic and biotic factors. Carrying capacity is the maximum population of a given species that a certain ecosystem can sustain indefinitely without being degraded.
What is an example of biotic potential?
Examples of Biotic Potential
The organism that produces the most organisms in that time frame has the most biotic potential. … If both organisms produce the maximum recorded number of offspring in a year, a human can only produce eight children. In one year, a dog has the potential to produce 48 offspring.
What are the main factors of environment?
Environmental factors include temperature, food, pollutants, population density, sound, light, and parasites.
Which of the following is typical of K selected species?
K-selected species are characterized by long gestation periods lasting several months, slow maturation (and thus extended parental care), and long life spans. In addition, they tend to inhabit relatively stable biological communities, such as late-successional or climax forests (see ecological succession).
Why do many non native species such as a prickly pear cactus brought to Australia from South America rapidly become abundant when first introduced?
Why do many non-native species, such as a prickly pear cactus brought to Australia from South America, rapidly become abundant when first introduced? There are fewer predators and parasites capable of attacking the non-native species in the new site.
Why are predators considered to be density dependent controls on their prey populations?
A second density-dependent limiting factor is predation. Predators kill and eat their prey, of course, so predation increases prey death rate and can cause negative growth rates – population decline.
What is an example of a carrying capacity?
Carrying Capacity Examples
Another example is the tree population in a forest. Let’s say a forest can have a carrying capacity of about a hundred trees. This means that the trees can grow without fiercely competing for sunlight, nutrients, and space.
What is the biotic environment?
[bī′äd·ik in′vī·ərn·mənt] (ecology) That environment comprising living organisms, which interact with each other and their abiotic environment.
What is resilience in environmental science?
ecological resilience, also called ecological robustness, the ability of an ecosystem to maintain its normal patterns of nutrient cycling and biomass production after being subjected to damage caused by an ecological disturbance.
