Biodiversity Hotspots — Set 3

Correct Answer: A. Tropical Andes

The Tropical Andes is often considered the most diverse hotspot in the world. Its high-altitude forests are frequently covered in mist and clouds. These forests support thousands of endemic species of amphibians and birds.

Correct Answer: C. Flowering plants

Flowering plants are easier to identify and count for scientific surveys. They form the primary structure of most terrestrial food webs. A high number of unique plants usually correlates with high diversity in other groups.

Correct Answer: A. Madagascar and the Indian Ocean Islands

This hotspot includes several island groups in the Indian Ocean. Madagascar is the largest and most ecologically significant part of this region. It is world-renowned for its unique baobab trees and diverse lemurs.

Correct Answer: B. Around 42%

The correct answer is 'Around 42%'. About 42% of all terrestrial vertebrate species are found only within these hotspots. This includes birds, mammals, reptiles, and amphibians. Their survival is entirely dependent on the conservation of these specific habitats.

Correct Answer: C. Over 10

This hotspot covers thousands of islands scattered across the southern Pacific Ocean. It includes countries like Fiji, Samoa, and Tonga. Island ecosystems are particularly vulnerable to extinction due to limited land area.

Correct Answer: A. Golden Langur

The Golden Langur is one of the most endangered primates in India and Bhutan. It is found in a small region between the Manas and Sankosh rivers. Its striking golden fur makes it easily recognizable in the wild.

Correct Answer: B. Succulent Karoo

The Succulent Karoo is located in South Africa and Namibia. It is the only arid-land biodiversity hotspot in the world. It is famous for having the world's richest flora of succulent plants.

Correct Answer: B. Indian Ocean

Sundaland spans the Indian Ocean and parts of the South China Sea. It encompasses some of the most complex marine environments on Earth. Coral reefs in this region are under high pressure from climate change.

Correct Answer: A. Mountains of Central Asia

This hotspot includes the mountains of Kazakhstan, Kyrgyzstan, and Tajikistan. It is a critical region for the conservation of wild fruit and nut trees. It is also an important habitat for the elusive Snow Leopard.

Correct Answer: C. Restricted to a specific geographical area

Endemic species have a limited distribution and cannot be found naturally anywhere else. Hotspots are defined by their high levels of these unique life forms. Loss of their specific habitat leads to the total extinction of the species.
