What are the 3 features of populations?
ADVERTISEMENTS: In most types of populations individuals are of different age. The proportion of individuals in each age group is called age structure of that population. The ratio of the various age groups in a population determines the current reproductive status of the population thus anticipating its future.

What are the 4 major types of population distribution?
Individuals within a population can be distributed at random in groups or equally spaced apart (more or less). These are known as random clumped and uniform distribution patterns respectively ([Figure 2]).
What are the three types of survivorship curves?
There are three types of survivorship curves and they are simply referred to as type I type II and type III. A type I survivorship curve shows individuals that have a high probability of surviving through early and middle life but have a rapid decline in the number of individuals surviving into late life.
What are the 3 types of population distribution and explain each one?
The three types of population distribution are uniform random and clumped. Uniform distribution is rare. Individuals are evenly spaced and there is fierce competition for resources In random distribution some individuals are close together and some are spread apart.

What overpopulation means?
Overpopulation refers to the exceeding of certain threshold limits of population density when environmental resources fail to meet the requirements of individual organisms regarding shelter nutrition and so forth. It gives rise to high rates of mortality and morbidity.
What is the main reason for population growth?
The primary (and perhaps most obvious) cause of population growth is an imbalance between births and deaths. The infant mortality rate has decreased globally with 4.1 million infant deaths in 2017 compared to 8.8 million in 1990 according to the World Health Organization (WHO).

Poor people are more vulnerable to both increasing population and pollution. … It is all leading to price rise affecting the poor the most and on multiple fronts. The loss of fertile land to construction also enhances poverty. Thus poverty gets aggravated due to increase in population and pollution.
