What are the broad adaptation that creatures and plants have made for survival in the desert biomes and tundra?

Answer 1

For plants, the aerioles and spines help reduce water loss. the spines also help protect the plant. this is seen in the opuntia or the mammillaria. the rosette form of the aloe and agave help the plant to get as much water as it can. the waxy surface of the aloe and agave help it to prevent water loss as well. Euphorbes have latex which is poisonous. white hairy surfaces on certain plants help it to reflect the hot sun

Answer 2

In the case of animals, the most obvious adaptations involve the ability to survive in extreme heat, and without much water. Certain desert animals are nocturnal, for example, so they only come out at night when the temperatures are cooler: bats, snakes, and many rodents have adapted in this way. Other creatures have learned to burrow into the soil or sand for protection when the sun is at its hottest; a few even are able to go into a sort of hibernation when the heat becomes too intense. Turkey vultures have a unique coping strategy-- they urinate on their legs to cool them.

Desert animals have also learned how to derive moisture from plants like the cactus, or they find nectar or sap and drink it. Birds, bats and lizards survive by eating insects, which contain some moisture. And it should be noted that like animals, plants too have developed unique survival skills for desert survival. Desert plants called Xerophytes (the cactus is a good example) have special means of storing and conserving water, and they often have few or no leaves. Other desert plants called Phreatophytes grow extremely long roots, which enables them to derive moisture at or near the water table.

Answer 4

Plants and animals living in the desert have developed adaptations to allow them to survive with little water supply
