: 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.
What is environmental resistance and give an example?
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. … Others cause a slow wind down in population growth.
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).
What do you mean by resistance in geography?
The resistance in the geography is the sum of the factors that are present in the environment and are conditions such as the drought and the floods and the other natural calamities.
Is environmental resistance a limiting factors?
environmental resistance The sum total of the environmental limiting factors, both biotic and abiotic, that together act to prevent the biotic potential of an organism from being realized.
What is the difference between biotic potential and environmental resistance?
Biotic potential refers to the ability of a population of a particular species to propagate under ideal environmental conditions — sufficient food supply, no diseases, and no predators. … Environmental resistance are factors that limit the biotic potential of an organism.
What is an example of a resistant ecosystem?
Sand pine scrub forests have low resistance to fires due to their thin bark and the ecosystem’s dry conditions. However, they have high resilience due to the cones requiring fire to open, which then release their seeds to colonize the charred ground.
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.
What are the characteristics of an environment that control or restrain the growth of a population?
Limiting factors are resources or other factors in the environment that can lower the population growth rate. Limiting factors include a low food supply and lack of space. Competition for resources like food and space cause the growth rate to stop increasing, so the population levels off.
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 do you mean by resistance?
Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). … All materials resist current flow to some degree.
What is meaning of the word resistance?
1 : an act or instance of opposing. 2 : the ability to withstand the force or effect of resistance to disease. 3 : an opposing or slowing force The car’s sleek design reduces wind resistance. 4 : the opposition offered by a substance to the passage through it of an electric current.
What does resistance mean in biology?
Glossary Search Results. biological resistance. The natural or genetic ability of an organism to avoid or repel attack by biotic agents (pathogens, pests, parasites, etc.) or to withstand the effects of abiotic agents (chemicals, pesticides, salt, wind, heavy metals, etc).
