Organisms that live in the _________ must be adapted to little or no rain and to extreme temperatures.
umka21 [38]

Answer: DESERT

Explanation:

Adaptation can be defined as the modification in the form, structure, function and behaviour of organisms in a habitat which enables them to live successfully and reproduce.

Desert is one of the types of the world biomes that is characterized with little or no rain and to extreme temperatures. Organisms, which includes plants and animals, must show some level of adaptation to able to survive the harsh environment.

The type of PLANTS which can survive in desert environment are called the XEROPHYTES. They show the following adaptations:

--> The roots are well developed: they grow down to great depths and branch extensively in order to absorb water

--> they possess swollen stems which contains water storage cells.

--> they have reduced leaves, for example in cacti in the form of spines, which helps to reduce water loss through transpiration.

The type of animal that survive in desert environment spend the hot dry seasons in a sleep-like torpid state called aestivation. This is so in order to avoid the heat. Their body size is usually small and less bulky: greater surface area in relation to body volume, thus enhancing heat loss from the body.

Organisms that live in the _________ must be adapted to little or no rain and to extreme temperatures.
