The observation that members of a population are uniformly distributed suggests that

(A) resources are distributed unevenly.

(B) the members of the population are competing for access to a resource.

(C) the members of the population are neither attracted to nor repelled by one another.

(D) the density of the population is low.

Short Answer

Expert verified
  1. The statement “resources are distributed unevenly” is false.
  2. The statement “the members of the population are competing for access to a resource” is true.
  3. The statement “the members of the population are neither attracted to nor repelled by one another” is false.
  4. The statement “the density of the population is low” is false.

Step by step solution

01

Population

In demographics, when the total number of organisms of a single species occupies a place to live there is called population.

02

Explanation of option ‘(A)’

The physical material that adds value to the life of living organisms like human beings and is obtained from the ecosystem is called resource.

Thus, the uneven resource distribution is considered as a clumped distribution.

Therefore, the given statement is false.

03

Explanation of option ‘(B)’

The different resources that living organisms compete for are food, space to live, and water.

Thus, the organisms’ distribution within a habitat is based on access to resources.

Therefore, the given statement is true.

04

Explanation of option ‘(C)’

Some of the important factors that determine the size of a population are natural changes like birth rate (natality), death rate (fatality rate), immigration, and outmigration.

Thus, the species within a population interact with each other.

Therefore, the given statement is false.

05

Explanation of option ‘(D)’

The demographers study population density as a measure determining the population distribution in a place by estimating the number of people occupying a geographical area.

Thus, the thinly-dispersed individuals are having a low-population density.

Therefore, the given statement is false.

Imagine that you are constructing a life table like Table 53.1 for a different population of Belding’s ground squirrels. If 485 individuals are alive at the start of year 0–1 and 218 are still alive at the start of year 1–2, what is the proportion alive at the start of each of these years (see column 3 in Table 53.1)?

In the fish called the peacock wrasse (Symphodus tinca), females disperse some of their eggs widely and lay other eggs in a nest. Only the latter receive parental care. Explain the trade-offs in reproduction that this behavior illustrates.

To estimate which age cohort in a population of females produces the most female offspring, you need information about the number of offspring produced per capita within that cohort and the number of individuals alive in the cohort. Make this estimate for Belding’s ground squirrels by multiplying the number of females alive at the start of the year (column 2 in Table 53.1) by the average number of female offspring produced per female (column 5 in Table 53.1). Draw a bar graph with female age in years on the x-axis (0–1, 1–2, and so on) and total number of female offspring produced for each age cohort on the y-axis. Which cohort of female Belding’s ground squirrels produces the most female young?
