Answer:
1.A population pyramid, also called an "age-gender-pyramid", is a graphical illustration that shows the distribution of various age groups in a population (typically that of a country or region of the world), which forms the shape of a pyramid when the population is growing.
2.India population is equivalent to 17.7% of the total world population. India ranks number 2 in the list of countries (and dependencies) by population. The population density in India is 464 per Km2 (1,202 people per mi2).
3.Physical factors that affect population density include water supply, climate, relief (shape of the land), vegetation, soils and availability of natural resources and energy.
How do I say so?
Mountainous areas make it difficult to construct buildings and roads. They are often inaccessible and remote.
Areas with extreme climates such as hot and cold deserts make it difficult to grow crops and access water.
Regions with dense vegetation cover, such as rainforests, provide challenges in terms of access and the lack of services make human inhabitation very difficult.
Flood plains present the risk of flooding, so building on them is often prohibited.
A lack of natural resources in an area presents significant challenges to economic development.
If land is infertile humans are unable to grow food leading to a low population density.
Locations that regularly experience natural hazards can discourage people from settling in the area.
