What would make the population density decrease?
Density Independent Limitation. Factors that decrease population growth can be defined as environmental stress including limitations in food, predation, and other density-dependant factors (Sibley & Hone 2002).
Which is likely to cause a population’s density to increase?
As population size approaches the carrying capacity of the environment, the intensity of density-dependent factors increases. For example, competition for resources, predation, and rates of infection increase with population density and can eventually limit population size.
What are the 3 distributions of population density?
Individuals of a population can be distributed in one of three basic patterns: uniform, random, or clumped.
What factors do not depend on population density?
What limiting factors do NOT typically depend on population density? Density-INDEPENDENT limiting factors such as: unusual weather such as hurricanes, droughts, or floods, and natural disasters such as wildfires. competition, predation, herbivory, parasitism, disease, and stress from overcrowding.
What will most likely occur if population density increases in a population that is density-dependent?
The correct option isb. In a density-dependent population, the birth rate will increase, if population density…
What is low population density?
World population distribution is uneven. Places which are sparsely populated contain few people. Places which are densely populated contain many people. Sparsely populated places tend to be difficult places to live. Population density is a measurement of the number of people in an area.
Density-independent limiting factor definition The limiting factor can restrict population size independent of how dense the population is. For example, a catastrophic event, such as an earthquake or a volcanic eruption, could cause a population decline regardless of population density.

What factors contribute to the increase/decrease of a population?
1. What factors contribute to the increase/decrease of a population? Abiotic factors (temperature, water, sunlight, nutrients in soil), biotic factors (predators, prey, competitors, predators, parasites, disease, etc.), and intrinsic factors (adaptations) affect the population size.
How can we decrease the population?
Reducing population growth
- Contraception.
- Abstinence.
- Reducing infant mortality so that parents do not need to have many children to ensure at least some survive to adulthood.
- Abortion.
- Adoption.
- Changing status of women causing departure from traditional sexual division of labour.
- Sterilization.
Which is a factor that will probably decrease population density?
The factor given in the choices that will probably decrease population density would be C. forest fire. Normal rainfall is beneficial to the ecosystem to help grow the vegetation and in result, benefits the consumers. Predators decrease the population while birth rate can also increase population. Rate!
In the real world, many density-dependent and density-independent limiting factors can—and usually do—interact to produce the patterns of change we see in a population.
What are the factors that affect population growth?
Key points 1 In nature, population size and growth are limited by many factors. 2 Density-dependent limiting factors cause a population’s per capita growth rate to change—typically, to drop—with increasing population density. 3 Density-independent factors affect per capita growth rate independent of population density.
Are there limits to the size of a population?
Some populations show cyclical oscillations, in which population size changes predictably in a cycle. All populations on Earth have limits to their growth. Even populations of bunnies—that reproduce like bunnies!—don’t grow infinitely large.
