Does environmental resistance decrease or increase the population growth of species?

A. Biotic potential increases the population of a species while environmental resistance decreases its growth. … Biotic potential and environmental resistance are both factors that limit the population growth of species.

How does environmental resistance affect population growth?

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 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.

What is the role of environment in increasing and decreasing of population in the organisms?

In the natural world, limiting factors like the availability of food, water, shelter, and space can change animal and plant populations. … Sometimes a population will grow too large for the environment to support. Other changes in limiting factors can cause a population to decrease.

What are the factors that may lead to a population’s biotic potential?

Biotic potential is the ability of a population of living species to increase under ideal environmental conditions – sufficient food supply, no predators, and a lack of disease. An organism’s rate of reproduction and the size of each litter are the primary determining factors for biotic potential.

Why does environmental resistance decrease the population growth of species?

Environmental resistance factors are things that limit the growth of a population. … Their adaptations to the environment and their reproduction rate affect the biotic potential of that species.

Which of the following increases a population?

What processes increase a population’s size? Births and immigration. (Immigration is the movement of individuals into a population, so births and immigration increase a population’s size.)

What type of population growth is affected by carrying capacity?

As competition increases and resources become increasingly scarce, populations reach the carrying capacity (K) of their environment, causing their growth rate to slow nearly to zero. This produces an S-shaped curve of population growth known as the logistic curve (right).

Why is population growth so rapid after the lag phase?

Propose some reasons why population growth is so rapid immediately after the lag phase in both diagrams of Model 2? … In most natural populations rapid exponential growth is unsustainable. As populations increase, environmental resistance causes the growth rate to slow down, until carrying capacity is reached.

What is required for a species to experience exponential growth?

Exponential Population Growth. When resources are unlimited, a population can experience exponential growth, where its size increases at a greater and greater rate.

What kinds of environmental problems are associated with population growth?

Environmental Challenges in Bangladesh

These include land degradation, water insecurity, high demand for energy, air pollution, land encroachment, loss of biodiversity, habitat destruction, and urban migration, lower quality of environmental sanitation, solid wastes generation.

How does population growth affect the environment essay?

Growing population will result in the depletion of natural resources such as water, fossil fuels (Hubert, 1982); deforestation and loss of ecosystems; and emergence of new diseases. It will also lead to more starvation, hunger and unhygienic living conditions in poor countries.

How is population growth good for the environment?

And higher levels of affluence lead to better, cleaner less polluting technologies (compare MDCs and LDCs). In brief, the direct evidence of the effect of population growth on the environment is clearer for forest loss and soil degradation than for pollution.

How do biotic potential and environmental resistance affect to the population growth?

Biotic potential increases the population of a species while environmental resistance decreases its growth. … Biotic potential and environmental resistance are both factors that limit the population growth of species.

What is the effect of biotic potential and population size on the exponential growth of a population?

(i) Biotic potential is the maximum reproductive capacity of an organism under optimum environmental conditions. If the biotic potential is high then the populaltion growth rate is increased.

IMPORTANT:  What is evolutionary and Behavioural ecology?

When a population is growing at its biotic potential?

Biotic potential is described by the unrestricted growth of populations resulting in the maximum growth of that population. Biotic potential is the highest possible vital index of a species; therefore, when the species has its highest birthrate and lowest mortality rate.
