What is true about population distribution?

What is true about population distribution?

Explanation: Population distribution in relation to space is a direct result of how individuals are “spread out” within the total area occupied by the population. The dispersion pattern can result from a biological strategy, but it can also result from the way in which the resources of the environment are dispersed.

Why would a population show clumped distribution?

Clumped dispersion is often due to an uneven distribution of nutrients or other resources in the environment. It can also be caused by social interactions between individuals. Additionally, in organisms that don’t move, such as plants, offspring might be very close to their parents and show clumped dispersion patterns.

How do ecologists study populations?

Ecologists study populations by examining their geographic range, growth rate, density and distribution, and age structure! This means that the larger the population gets, the faster it grows!

Which factor is most likely to have a density-independent influence on population growth?

The factor that is most likely to have a density-independent influence on population growth is Extreme weather conditions. Density-independent factors such as weather and climate, exert their influences on population size regardless of the population’s density.

Is disease a density-independent factor?

Density Dependant Limitation Limitations to population growth are either density-dependant or density-independent. Density-dependent factors include disease, competition, and predation.

Is disease biotic or abiotic?

Biotic diseases sometimes show physical evidence (signs) of the pathogen, such as fungal growth, bacterial ooze, or nematode cysts, or the presence of mites or insects. Abiotic diseases do not show the presence of disease signs.

Is a pond biotic or abiotic?

Pond and Lake Ecosystems A pond or lake ecosystem includes biotic (living) plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions. Pond and lake ecosystems are a prime example of lentic ecosystems.
