The Amazon in South America is the largest, most diverse tropical rainforest on Earth, covering an area of five and a half million square kilometres (2.1 million sq mi) and thus is called as the lungs of Earth. It is called so because they generally draw in carbon dioxide and breathe out oxygen. It accounts for more than half of the planets remaining rainforest and is home to more than half the world's species of plants and animals.

The Arabian Desert, a vast desert area in extreme southwest Asia, covers almost all of the Arabian Peninsula. It is the continent's largest desert region, covering an area of around 900,000 square miles (2,300,000 square km), and the second largest on Earth, in northern Africa, exceeded in scale only by the Sahara.

The correct answer is D .

Oasis are a fertile area in a desert or semi-desert setting (often with a date palm grove). Habitats for animals and plants can be found. In the desert or arid regions of the Arabian Peninsula, in the Sahara Desert and in many other desert regions of the world, oasis are located.

The correct answer is B .

In regions between 5 and 30 degrees latitude, tropical deserts are found. It's a very severe setting. On Earth, they have the highest monthly average temperature. The rainfall is sporadic; in a few years, precipitation can not be observed at all. Many tropical deserts are covered with sand and rocks, in addition to these harsh environmental and climate conditions, and therefore too flat and deficient in vegetation to stop the wind. Because of intense aridity, heat and the lack of vegetation, no large communities can live in tropical deserts; only unique flora and fauna with special behaviour and physical mechanisms are supported. While raw and barren, tropical deserts are considered to be important sources of natural resources and play an important role in economic growth.

The correct answer is A .

 Coniferous forests- They are also called Taiga. They are tall, softwood evergreen trees. Chir, pine, cedar are important variety of trees in these forests. Silver, fox, mink, polar bear are the common animals found here.
