Four factors that affect population growth:

1. Birth Rate: The number of a baby being born in the population

2. Death/mortality rate: The number of death happening in the population

3. Immigration: The number of people entering the population

4. Emigration: The number of people leaving the population

<h3>Further explanation </h3>

A population is a group of individuals of the same species that live in a particular area or the number of people living in the same area, for example, a city population means the number of people living in that city.

Population growth is the change in a population over time. It can be increasing or decreasing, depend on those factors above.

The population's growth rate increase when the birth rate is higher than the death rate, or the emigration is lower than the immigration. When the death rate is higher than the birth rate or the emigration rate higher than immigration rate the population's growth is decreased. The population growth is a result of a combination of natural increase and migration flows.

There are four major factors that affect population growth:

<span>
Birth rate<span>: The number of births per 1000 people in a year. This has a positive effect on population growth. </span>This makes sense, as people being born adds to the population.</span>

Death rate: The number of deaths per 1000 people. This has a negative effect on population growth. People dying lowers the total population.

Immigration<span>: The number of people entering the population. This has a positive effect on population growth. People entering the population increases it.</span>

Emigration<span>: The number of people leaving the population. This has a negative effect on population growth. People leaving the population decreases it. </span>

Identify the position on the graph that gives the carrying capacity of the population.
Darina [25.2K]

The carrying capacity of any individual biological species is the maximum size of the population which can sustain indefinitely in that environment provided the necessary requirements like food, water and other environmental conditions are available.

The carrying capacity in the graph is the point on the graph where the line of population is horizontal. The graph has the population in y-axis and time period on x-axis. Alternatively if in the carrying capacity graph the line becomes parallel to x axis then it gives the carrying capacity. Here, at the point 2000 on y-axis and starting from 15 months in x-axis is the point of carrying capacity is marked with red horizontal line and green border in the image attached.
