Question

Most of the tree dwellers occur in
A. Deciduous forests
B. Tropical rain forests
C. Tundra
D. Grassland

Answer 1

Hint: Forests are the biotic components of the ecosystem. They are a rich source of flora and fauna . They are used to maintain ecological balance of the environment. They help to maintain a constant balance of gases in the human environment. Forests also helps in refreshing the air and prevents air pollution.

Complete answer:
Tree dwellers are those forests in which a very large number of trees exist . The trees will furnish where all the conditions are favourable like that of the high rainfall. Tree purifies the air . They bind the soil particle together and prevent soil erosion.

Now let us match this with given options :-
> Option A:
Deciduous forests :- They are also known as temperate broadleaf forest. They are largely covered with trees . But they lose their trees every year . Thus they can not be said to be tree dwellers.

> Option B:
Tropical rain forests :- these are also known as evergreen trees . These have large canopy of trees and receive heavy rainfall. The trees persist throughout the year . Thus they are known as tree dwellers.

> Option C:
Tundra: these are present in the northern sides . They have very limited trees. These are only covered with shrubs and herbs . They are covered with mat like vegetation. So, they are not known as tree dwellers.

> Option D:
Grassland: this type of forest is dominantly covered only by grasses. Rush is also found in these forests. They are also covered with legumes and also by clover. So, they are not tree dwellers.

Hence, the correct answer is option (B).

Note: Tropical rainforests are forests which are rich in biodiversity and consist of many species of plants and animals . They have 30-40 m tall trees and are covered under 4-5 strata’s . The plants of these forests have buttress roots . They are characterised for maximum leaching.
