Why are population pyramids sometimes called age structure diagrams

A population pyramid consists of a vertical number line, but instead of numbers its ages. The diagram shows how much of the population is in each age group, and also divides it again to show if the person is a boy or a girl. These pyramids/diagrams help compare the ages and genders of a population in an easy way. (Ex. Large amount in the youth but small amount in the elderly would mean economic problems, Ex. Many boys on one side but not many girls in reproductive age would mean population will decline)

QUESTION POSTED AT 15/12/2019 - 10:04 PM

What location on Earth experiences the least change in daylight hours as the seasons change and why?

The correct answer here is: The equator.

This is because the seasons are caused by a small tilt in the eaths axis: the Axis is not straight with respect to the movement around the sun, but it's tilted, pushing one pole (North or south) closer or away from the Sun.

This tilt affects the pole region the most and the equator region the least. At the poles the tilt causes extreme variations in the lenght of daylight hours: from perpetual daylight for days to no daylight for days.

The effect is strongest at the poles and weakest far away from the poles: at the equator.

Why river Ganga does not dry during summer

The Ganges River, or river Ganga is known to be one of the largest rivers in the world which means that there is still a huge reserve of water. The summer may dry up the Ganges river and makes it low tide, but it will not totally dry up because the summer is followed by some rainy days which will make the Ganges river become high tide. Whenever there are downpours in the country, then the water level of the Ganges river will go up and the water will be replenished.

Organisms in a food web are on the highest trophic level of feeding stages. c. Organisms in a food web have equivalent survival rates to those in a food chain because they are herbivores. d. Organisms in a food web have one primary food source, which ensures their health.

A.Organisms in a food web have alternative foods to eat if one of their food sources diminishes or disappears.

Food chain refers to a process cycle from producer to consumer to decomposer.
