Small leaves (usually waxy) and cactus spines lessen the loss of water due to transpiration.
A good number of desert plants shed their leaves to avoid water loss by transpiration during most favourable conditions of transpiration. These are high temperature, low humidity and greater sunshine etc.
There isn't much water and there is too much sunlight. leaves need enough water and sunlight to be healthy. Or not, they will be not healthy and be short.
because they don't receive enough moisture (water in vapor form)
Most likely to decrease its surface area to volume ratio (SA:V) thus minimising water loss.
Small leaves help cut down on water loss by the plant in a desert.
Small leaves cut down on water loss due to transpiration and evaporation.
To reduce water lost by evaporation.
When the leaves of the plant shed off there will be no chlorophyll to trap sunlight, so the water will not evaporate...
Litter
The leaves of plants may go brown because of a number of reasons. Some plants' leaves go brown due to lack of enough water while others do so as a natural process when they are about to shed their leaves.
the loss of leaves help a plant survive winter becuase the plant doesnt have to lose and give water much more
A deciduous plant drops all of its leaves in the fall. A non-deciduous plant keeps most of its leaves throughout the year. Most non-deciduous temperate trees happen to be conifers but not all conifers are non-deciduous. Most tropical trees are non-deciduous.

Autumn (fall) is the season when deciduous tree shed their leaves in the north.
Most desert plants have the same parts as plants from areas with more rainfall. Some, such as cacti, have lost their leaves and replaced them with spines. Some plants grow leaves during rainy seasons and then shed them during periods of drought. They may do this several times each year. Other plants allow their leaves to shrivel during drought and then spring back to life after a good rain.
when there is drought the water is scarce. so due to that the water absorbed by the tree is less. this water is not enough for the trees. the scorching heat of the sun the tree lose their leaves because not getting water properly
Yes, and the season is winter.
All of them.
because to protect themselse from hot season
to avoid descication (water loss)
When the leaves of the plant shed off there will be no chlorophyll to trap sunlight, so the water will not evaporate...
because at this time their leaves are not required and the wood is used mainly.
as plants shed leaves they form a loose layer called litter kind of answering it ?
