Answer #1

Answer- The correct option is competition.

  • All the remaining options are natural disasters which have potential to alter population size but they are not density dependent, but these influence in a density independent manner.
  • Only competition is the density dependent factor.
  • Within a population competion generally occur to compete for resources, if density is high more chances of competition between individuals of population than at low density.
  • High rate of competition results in decline in population.

Population Growth Equation In the population growth equation, the letter “r” is defined as the per capita rate of increase, which is the difference between the per capita birth rate (the number of offspring produced per unit of time by an average member of the population) and per capita death rate (average number of deaths in the population per unit time). What does the value of “r” indicate about a population? All of the following characteristics are typical of a...
