Question

1.
What is meant by the growth rate of population?
2.
What are the three important attributes of population composition?​

Answer 1

Answer:

Specifically, population growth rate refers to the change in population over a unit time period, often expressed as a percentage of the number of individuals in the population at the beginning of that period. This can be written as the formula, valid for a sufficiently small time interval:

Explanation:

1Population density refers to the size of any population in relation to some unit of space. It is expressed in terms of the number of individuals or biomass per unit area or volume, as for example, 500 teak trees per hectare; 40 lions per 100 km2, 5 million diatoms per cubic meter of water. Population density is seldom static and it changes with time and space

2Natality refers to the rate of reproduction or birth per unit time. It is an expression of the production of new individuals in the population by birth, hatching, germination or fission.

Answer 2

Answer:

1.The "population growth rate" is the rate at which the number of individuals in a population increases in a given time period, expressed as a fraction of the initial population.

2. The three important attributes of population composition are as follows:

• In a population, the number of individual expresses total size. Individual's number per unit volume of environment defines density of population.
• Vital index defines a birth-death ratio. ...
• The power of growing is inherited by each population.
