Natural Vegetation and Habitats

What makes up most of the Canopy Layer is a tangled mix of vegetation including branches, vines and trees of different sizes. The trees rise to as much height as possible to gain maximum sunlight. 

Tropical rainforests have four layers: Emergent Layer, Canopy Layer, Understory, Forest Floor. 

Forests and grasslands are an excellent binding material that keeps the soil intact and healthy. They support many habitats and ecosystems, which provide innumerable feeding pathways or food chains to all species. Their loss would threaten food chains and the survival of many species.

The ocean is considered the most stable ecosystem because it has a high heat capacity, vast volume, and relatively constant chemical and physical conditions compared to terrestrial ecosystems like forests or deserts.

During summer the land becomes dry and rainfall induces formation of grass and hence heavy rainfall during summer produces grasslands.

Deodar cedar is a conifer, evergreen, broadly pyramidal with gracefully pendulous branches, drooping central leader, spreading and flat-topped with age. Long branches bearing spur-like stems with whorled needles. Leaves are light blue or grayish green and softer. Deodar is not a dicot, fern or mosses. 

Conifers are typically found in cool, temperate regions, and in India, they are characteristic of the Himalayan mountain range.

Acacia trees are typically found in savanna or arid regions, not in the dense, high-rainfall equatorial rainforests where species like mahogany and green heart thrive.

Temperate regions have the climate suitable for large-scale dairy farming and the growth of coniferous forests, which provide softwood.

The Tundra biome is characterized by migratory birds like geese, jaegers, and shorebirds that arrive during the short summer season to breed.

The Sahara Desert is an extremely arid environment with very limited vegetation due to scarce rainfall and harsh temperatures. In contrast, the other listed regions support significantly more plant life.

Rain forests provide a warm, humid, and stable environment that supports the highest biodiversity of plants on the continent. The other regions are much drier and have less dense vegetation.

The Sunderbans is a natural region in Bengal. It is the largest single block of tidal halophytic mangrove forest in the world. A mangrove is a tree, shrub, palm or ground fern, generally exceeding one half metre in height, that normally grows above mean sea level in the intertidal zone of marine coastal environments and estuarine margins. A mangrove is also the tidal habitat comprising such trees and shrubs.

The Sundarbans contain the world's largest mangrove forests and one of the most biologically productive of all natural ecosystems. Located at the mouth of the Ganges and Brahmaputra Rivers between India and Bangladesh. The mangrove habitat supports the single largest population of tigers in the world.

Mangroves are marshy area found in tropical deltas and saline ponds near sea shores, e.g., Rhizophora. It has water storage tissues to dilute salt content in cells. It is a genus of tropical mangrove trees, sometimes collectively called true mangroves.
