Question

differentiate between dessert vegetation and tundra

Answer 1

The tundra and the desert are two biomes with a decreased amount of rainfall. Due to the decreased precipitation rate, the species diversity in these biomes is less as compared to other biomes like the savannah, grasslands, and chaparral. However, the number of individuals per species is often large.

Tundra
The tundra biome is located mainly in the northern Arctic Circle and in the Arctic Peninsula in the Southern Hemisphere. The vegetation mainly comprises grasses, herbs, and lichens.
This area faces extremes of nature where the temperature reaches -50o F in the winters. Summers are very short in this region. Due to this factor, only the topmost layer of the soil is thawed. The deeper layers of soil remain frozen throughout the year which is termed as “permafrost.” A harsh climate, lack of soil and nutrients makes it a tough place to survive.

The most successful plants in the tundra vegetation are mosses and lichens. They require minimal soil to survive. In the tundra, the roots of plants are wide and shallow to sustain rapid, icy winds. Some higher plants as the Juniper and Willow have adapted themselves as dwarfs and grow horizontally along the ground.

The animals inhabiting this area mainly include: caribou, deer, lemmings, weasels, mice, and hunters such as wolves. The animals most successful in this region are: Polar bear, walruses, seals, penguins, and Arctic foxes. Many migratory birds visit the tundra in the summer. They choose this region as their breeding grounds.
The tundra is one of the most fragile biomes. The food chain in this region is relatively simple and so it is easy to get disrupted.

Answer 2

the Tundra biome is located mainly in the Northern Arctic circle in the Arctic Peninsula in the southern hemisphere or vegetation mainly comprises grasses Herbs and lichens.
deserts are the driest areas of the planet. this biome also has extremes of temperature on both sides. the vegetation includes here is cactus
