Question: What do you think environmental resistance means?

: 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 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.

How would environmental resistance affect the survival of an organism?

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 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.

How is the understanding of ecology helpful?

Ecology enriches our world and is crucial for human wellbeing and prosperity. It provides new knowledge of the interdependence between people and nature that is vital for food production, maintaining clean air and water, and sustaining biodiversity in a changing climate.

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 carrying capacity in environmental science?

Carrying capacity can be defined as a species’ average population size in a particular habitat. The species population size is limited by environmental factors like adequate food, shelter, water, and mates. … Explore carrying capacity with these curated classroom resources.

Why do we need to consider the ecosystem carrying capacity?

When an ideal population is in equilibrium with the carrying capacity of its environment, the birth and death rates are equal, and size of the population does not change. … Populations larger than the carrying capacity are not sustainable, and will degrade their habitat.

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).

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.

How do animals responded to environmental stress?

Both plants and animals respond to stress by using adaptations that help them evade, tolerate, or recover from stress. … Bradshaw (1972) noted that basic biological differences between plants and animals will have diverse evolutionary consequences, including those influencing how they deal with stress.

How does ecosystem affect in our daily life?

As a society, we depend on healthy ecosystems to do many things; to purify the air so we can breathe properly, sequester carbon for climate regulation, cycle nutrients so we have access to clean drinking water without costly infrastructure, and pollinate our crops so we don’t go hungry.
