Solution: d)

The Himalayan range is a confluence of the Trans-Himalayan zone, Himalayan zone, and Northeast zone. These zones have Tropical, Temperate and Tundra type of climate which makes it rich in biodiversity of flora and fauna.

Solution: d)

An algal bloom or algae bloom is a rapid increase or accumulation in the population of algae in freshwater or marine water systems. It is often recognized by the discoloration in the water from the algae’s pigments.

The term algae encompasses many types of aquatic photosynthetic organisms, both macroscopic multicellular organisms like seaweed and microscopic unicellular organisms like cyanobacteria. An example of a macroscopic algal bloom is a kelp forest.

Solution: b)

Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth.

Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. 

Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration.

Volcanic eruptions release gases into the atmosphere. Volcanic gases are primarily water vapour, carbon dioxide and sulphur dioxide.

Solution: c)

Biodiversity is greater in tropical regions due to warm and humid climate. It also decreases with altitude due to unfavourable conditions.

Solution: d)

Created in 1988 by the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP), the objective of the IPCC is to provide governments at all levels with scientific information that they can use to develop climate policies. IPCC reports are also a key input into international climate change negotiations.

The IPCC is an organization of governments that are members of the United Nations or WMO. Thousands of people from all over the world contribute to the work of the IPCC. The IPCC does not conduct its own research.
