Question C.1:

Each natural vegetation zone of the world has its unique wildlife.

Answer:

 The natural vegetation of particular region is resultant factor of different attributes of nature, such as amount of rainfall, sunlight and wind conditions. This helps in the growth of peculiar kind of flora and fauna for the given region that have adapted to the local conditions most suitably. Thus each natural vegetation zone of the world has its unique wildlife.

Question C.2:

Lumbering is an important occupation in the coniferous forests.

Answer:

The coniferous forests generally have evergreen tall and straight trees with needle shaped leaves. These trees yield soft wood (which in turn is used for a variety of products such as paper, newsprint etc.) and they grow in pure stands with one species covering large part of the area. This makes lumbering a significant occupation in the coniferous forests.

Question C.3:

Fur bearing animals are found in the Taiga, and the Tundra.

Answer:

 The climatic conditions of the Taiga and the Tundra are very harsh with significantly low temperature all throughout the year.

Question D.1:

Describe the natural vegetation and wildlife of the tropical rainforests.

Answer:

Tropical rainforests are most luxuriant and rich in terms of wildlife and vegetation. These forests are also known as Selvas and are found in the Equatorial belt, that is, in the Amazon and the Orinoco river basin of South America, in the Zaire basin of Africa and in other countries like Indonesia, New Guinea, Malaysia, Vietnam and Philippines. 

The richness of natural vegetation in these evergreen forests is due to the persistent hot and wet climate throughout the year. The trees are tall, broad-leafed and have thick canopy at the top that prevents sunrays from reaching the surface of the ground. Therefore, the interiors are dark and damp, providing a suitable environment for the growth of mosses and ferns along with creepers and climbers like lianas. A variety of hardwood trees are found here such as mahogany, rosewood, ebony, rubber and cinchona. The trees mostly grow in cluster, thereby, making commercial activity very difficult.

These tropical rainforests are also the home of a variety of animals that thrive upon its immense vegetation. Most important tree-dwelling species found here are monkeys, apes, bats, sloths, tree lizards and tree iguanas. Some carnivorous animals are also found here, such as pumas and jaguars. Hippopotamuses and reptiles like crocodiles, alligators, turtles and big snakes also dwell in the swampy regions of these rainforests.

Question D.2:

Describe the location and special features of Mediterranean forests.

Answer:

The Mediterranean forests are usually located in the warm temperate regions on the western margins of the continents on both the sides of hemisphere. These forests are uniquely known for long, dry summers and rainfall in the winters. These forests are found mainly in the regions of Southern Europe (Spain, Greece, Turkey, Portugal, Yugoslavia, South France and Italy), West-Asian countries (Lebanon, Syria, Israel and Cyprus), North-Western Africa (Tunisia, Algeria, Morocco), Central Chile in South America, California in North America, South Africa and in Southern Australia.

In these forests, the winters are cold and wet while the summers are hot and dry. Therefore, the trees sometimes have waxy leaves, thick barks and long roots to avoid the loss of moisture. The trees are of medium height, widely spaced, not very dense and have broad evergreen leaves. The main species found here are figs, firs, olive, cedar,cork oak, pine, cypress and myrtle. These forests are most suitable for citrus fruits like lime, lemon and orange. Grapevines are cultivated here commercially.

The wildlife in these regions is not very prominent since the forest land is usually cleared to give way to the agriculture of large-scale fruit orchards. However, 
domestic animals and cattle are found  here in abundance.
