a. To determine population density, a scientist must know Population size and space occupied. ( formula for population density = number of organisms / space occupied).
b. the pattern in which the organisms are equally spapced throughout their habitat is known as Uniform dispersion. ( In this even distribution the didtance between two organisms is maximized).
c. The maximum rate at which the population can increase under ideal condition is known as Biotic potential. ( this is mainly the capacity of the individual to reproduce under ideal conditions or optimal condition).
d, When two members of the same species, rely on the same resources, Interspecific competition results.
e. If the number of surviving organisms in an endangered population falls below the number needed to cope with variations in the environment, the population may not survive. this is known as Minimum viable population size
f. Similar species are able to reduce competition by occupying different non-overlapping niches. this is known as Resource Partitioning.
g. A model that can help people visualize their impact on the environment by estimating the amount of resources needed to support them is known as Ecological footprint
h. The pattern in which organisms are densely grouped in areas of their habitat with favourable conditions for their survival is known as Clumped dispersion
i. On an isolated island, the two determinants of population dynamics are Natality and Mortality
j. the maxium number of organisms that can be sustained by available resources over a given period of time is the Carrying capacity
