Answer:
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.[1] Males are conventionally shown on the left and females on the right, and they may be measured by raw number or as a percentage of the total population. This tool can be used to visualize the age of a particular population.[2] It is also used in ecology to determine the overall age distribution of a population; an indication of the reproductive capabilities and likelihood of the continuation of a species.

Answer:
An alicyclic compound contains one or more all-carbon rings which may be either saturated or unsaturated, but do not have aromatic character. Alicyclic compounds may have one or more aliphatic side chains attached...hope this helps :)
Answer:
(a) Desert- In a desert environment, the temperature is relatively very high during daytime due to high absorption of sunlight and at night it again cools down. There is little or no precipitation here. This region includes the equatorial and some parts of the tropical region.
(b) Arctic tundra- This region lies in the higher latitudinal areas extending from the arctic to the extreme poles. The temperature here is extremely cold and precipitation is low. The plants and trees here are short in height.
(c) Temperate grassland- These are the mid-latitude areas covering the extensive grasslands of both the northern and the southern hemisphere. The temperature and precipitation level here are both moderate.
(d) Tropical rain forest- These are the regions that covers the vast rain forest areas in the tropical region of both the hemispheres. The temperature here is high is relatively high and high moisture content. As a result of which the rate of evaporation is high and rainfall is maximum. The region is rich in diverse trees and plants species.
(e) Temperate deciduous forest- These are the regions covering the mid latitudes that are rich in the deciduous forest. These are the dry forests comprised of various plant species. The temperature in this region is very moderate and summers are comparatively much cooler. Precipitation in this region is also quite moderate.
