Chapter-8 Human Environment Interaction – The tropical and Subtropical Region.

Explanation:

The region of South America that the Amazon River and its branches feed is known as the Amazon basin. A total of 6,300,000 km2 (2,400,000 sq. mi), or about 35.5 percent of South America, is covered by the Amazon River region. South America is where you can find the Amazon Basin.

Explanation:

The South American Amazon Basin is drained by the Amazon River and its branches. Most of the region is covered by the Amazon jungle, also called Amazonia. Plant development is dense and the diversity of animal residents is comparatively high due to the abundant evergreen and coniferous woods and heavy rains. Very little sunshine hits the earth because of the dense forest canopy that acts as a roof. Because the earth is always damp and gloomy, only plants that can withstand shadow can grow here. The Amazon Basin's inhabitants grow cassava, bananas, and sweet potatoes. Additionally, cash products like coffee, maize, and cocoa are produced.

Explanation:

In the Amazonian rain forests, you're most likely to see toucans, hummingbirds, and birds of paradise, which have brightly colored feathers and large bills. The brightly colored birds of paradise are the birds most likely to be located in the Amazonian jungle.

Explanation:

In terms of its watershed and cultural importance, the Ganga is India's most significant river. India's towns and the river are both regarded as sacred. People think that bathing in the Ganga will cleanse their misdeeds away and grant them moksha. Due to the fact that cities on its river are also revered, thousands of people visit here each year. The towns that make up the Ganga have cultural importance for this reason.

Explanation:

The larger one-horned rhino (or "Indian rhino") is the biggest of the rhino species. Rhino populations, which were once common throughout the entire northern Indian subcontinent, drastically declined as a result of pleasure hunting and killings for being farming pests.

Explanation:

The correct option is (a) Birds.

Tropical American woods are home to a type of bird called the toucan. The Ramphastidae family includes them. They consume both fruits and meat. Their distinctive big, vibrant bills are well recognized. They are the noisiest type of bird in the woodland and are non-migratory. The typical lifetime of Toucans is 20 years.

Explanation:

The correct option is (c) Amazon.

A plant called manioc. (Or Cassava, or Yucca, especially in Latin America). It thrives in tropical regions and is a member of the spurge plant genus. Its delicious roots are the reason it is cultivated. Manioc can be used in dumplings, soups, stews, and gravies and needs to be thoroughly prepared in order to detoxify it before consumption. The main meal in Amazon is manioc. Africa and South America have warm temperatures where manioc is grown. (Or generally referred to as Cassava). Its roots are edible, and they produce the third-highest output of carbohydrates per farmed area.

Explanation:

The Correct option is (b) Hooghly

The Ganga river splits into two tributaries near Murshidabad, and one of those parts is known as Hooghly. Kolkata is situated on the shores of the Hooghly, which runs south. This is the best choice as a result.

The incorrect options are: (a), (c)

• (a) Orange- The River traverses Southern Africa. As a result, it is not only on a different globe than Kolkata, but also in a distinct region. As a result, this choice is flawed. Upington is the only significant city located on the Orange River's shore.

• (c) Bhagirathi - One of the two primary headstreams (sources) for the river Ganga is the Bhagirathi. Devaprayag is the significant village on its shore. Consequently, this choice is also untrue.

Explanation:

The Correct answer is (a) Coniferous trees

Coniferous trees are evergreen bushes and trees with needle-shaped real cones and aril late-shaped fruits. The modifications of the coniferous trees enable conifers to live in the regions where weather is very cold and dry. These trees do not generate blooms and they develop cones to store their seeds.

Explanation:

The correct option is (b) Delta area

The Delta region is home to Bengal tigers. Sundarbans is where one can find Bengal leopards. The Brahmaputra and Ganga river confluence. A distinct subspecies of the Panther tigress, the Bengal tiger is a type of tiger. It is threatened by hunting, bad luck, and territorial fragmentation, and by 2011 it was estimated that there were fewer than 2,500 wild people left. It is believed that none of the Tiger Conservation Landscapes within its purview are substantial enough to aid a productive group of more than 250 adults.

Explanation:

Explanation:

 Because of the rapid pace at which growth is occurring, rain forests are disappearing. Daily destruction of the ecologically varied rain forests occurs. According to estimates, the Amazon basin's rain forest has been losing a significant amount of land each year. As a result, when it rains, the topsoil is washed away, leaving the verdant, green woodland to become a desolate environment.

Explanation:

 Because the alluvium soil along the Brahmaputra Ganga River is one of the finest types of land for farming, paddy is grown there.  Paddy is simple to reach by the waterway and requires a lot of water to develop. Half of all Indians live on this one-fourth of the territory.  Rich alluvial soils, wide open spaces, perennial waterways that move slowly, and favourable weather encourage extensive agricultural growth. Thanks to the extensive use of irrigation, Punjab, Haryana, and the western portion of Uttar Pradesh have become India's grain-growing regions. (The prairies are considered the granaries of the world. The entire plain has a dense network of highways and railways, with the exception of the Thar Desert, which has aided in widespread industrialization.
