Natural Vegetation and Habitats

Mangroves are salt-tolerant trees that grow in tropical and subtropical regions, typically in coastal areas.

Xerophytes are plants adapted to survive in environments with little liquid water, such as deserts.

Lotus, hydrilla, and hyacinth are all hydrophytes, which are plants that have adapted to live in aquatic environments.

Xerophytes are plants adapted to survive in environments with little liquid water, such as deserts or ice-covered regions.

The primary limiting factor for vegetation growth in desert environments is the lack of sufficient water.

It means that the ecosystem is deteriorating.

Sundari trees are the characteristic species of the Sundarbans mangrove forests, which are a type of tidal vegetation.

The Savannas are the vast tropical grasslands found primarily in Africa.

The Pampas are fertile South American lowlands, specifically in Argentina, characterized by vast, treeless grasslands.

This is the correct option. Coconut tree is not a part of the flora of Pachmarhi Biosphere Reserve.

Rain forests belong to the tropical wet climate group. Rainforests now cover less than 6% of Earth's land surface. Scientists estimate that more than half of all the world's plant and animal species, live in tropical rain forests. Tropical rainforests produce 40% of Earth's oxygen. A tropical rain forest has more kinds of trees, than any other area in the world. Scientists have counted about 100 to 300 species, in one 2 1/2-acre (1-hectare) area in South America. Seventy percent of the plants in the rainforest, are trees.

Tropical monsoon forests are found in regions with distinct wet and dry seasons, which includes parts of South Asia (like Sri Lanka) and parts of Eastern Africa.

Tidal forests, which grow in saline water in coastal areas, are commonly known as mangrove forests. They are vital for protecting coastlines from erosion.

Natural vegetation is often referred to as the 'mirror of climate' because the types of plants that grow in a region are directly determined by the local climate, such as temperature and rainfall.
