Question

Desert, rain forest, tundra, etc, are examples of
A) Community
B) Biome
C) Ecosystem
D) Population

Answer 1

Hint:-A community may also be known as a biocoenosis. A group of population, involving two or more species, sharing the same geographical area is known as a community. In a biome, the plants and animals share the same climatic features. A biome consists of plants and animals having common interests in the type of environment they exist in. An ecosystem is an interaction between the plants and animals existing in an area with each other and with their surroundings. A population consists of one type of species or group that exists in an area having common beliefs, features and culture.

Complete step-by-step solution:-
A desert is associated with a typical climate i.e. described as an area with minimal precipitation and where only those species survive which can tolerate harsh environmental conditions. In deserts, the plants and animals are adapted to use their metabolic waste water for their other requirements. They are adapted such that they require minimal amounts of water and that they can store water for several years and even survive without water for long periods.
The rain forests receive heavy and non-stop precipitation. The annual rainfall in the rain forests is upto 2.5 to 4.5 m. Two types of rainforests are namely, the tropical and the temperate. In these regions, rains last almost throughout the year.
The typical feature of the tundra region is that the temperatures are low. This results in limited plant growth, resulting in patchy landscape. The plants supported here are low to the ground such as grasses, mosses and small shrubs.Thus, the desert, rainforests and tundra are examples of biomes.
The correct answer is Option B.

Note:- The low temperatures of the tundra region is due to the fact that below the surface, the land is permanently frozen. The tropical rain forests are located near the equator. The temperate rainforests are located near the coasts. The lack of water gives deserts their climatic properties.
