Question

Even, clumped or random represents which property of the population?
(a) Habitat
(b) Dispersion
(c) Size
(d) Density
(e) Growth rate

Answer 1

Hint: Demographic analysis is a method for determining a population's age, gender, and racial composition, as well as how it has evolved over time as a result of the basic demographic processes of birth, death, and migration.

Complete answer:
Density and size are useful indicators of population size and density. Scientists can learn more about a species' biology and ecology by looking at how individuals are distributed spatially. The spatial interaction between members of a population within a habitat is depicted by dispersion or distribution patterns.
The demographic study is based on the estimation of a population's many elements. Dispersion is a key factor in defining the distribution of species in a given area and is used in demographic research.
Individuals in a population can be distributed in one of three ways: uniformly spaced, randomly dispersed with no discernible pattern, or grouped in groups.
Plant species that restrict the growth of neighbouring individuals show uniform dispersion. Surrounding plants are killed in a circle around the individual sage plants, resulting in a constant space between them. Uniform dispersion is also seen in animals that have specified territories, such as nesting penguins.
Dandelion and other plants with wind-dispersed seeds that grow wherever they fall in a good environment are examples of random dispersion. Plants that drop their seeds directly to the ground, such as oak trees, or animals that dwell in groups, such as schools of fish or elephant herds, exhibit clumped dispersion.
In this approach, the dispersion pattern of individuals within a community reveals more information than a simple density measurement about how they interact with one another and their surroundings. Solitary species with a random distribution may face similar challenges to sociable species clumped together, just as lower density species may have more trouble finding a mate.

As a result, option B is the proper response.

Note: The main determinants of how a population changes through time are the demographic characteristics of that population. The population remains steady if birth and death rates are equal. If birth rates surpass death rates, the population will grow, but if birth rates are lower than death rates, the population will shrink.
