the leaf decay is caused due to the wilting of leaf i.e caused by excessive loss of water. the rate of wilting increases due to increase in temperature as high temperature causes excessive loss of water. in summers the heat intensity increases causing water loss while in winters heat is less comparatively.

∙ 11y agoI'm not sure whether you are asking what makes the leaves fall or what's the purpose of trees losing their leaves in winter.
Mechanically, as the weather gets cold signaling winter is coming, the trees release a hormone that causes a kind of growth at the base of the leaf that severs the leaf from the tree.
Deciduous trees throw off their leaves in winter because there's little sunlight and water for leaves to do their function of making food for the tree. If they were permanently attached, in some years, the a spring warm spell come too early. This can fool the leaves into starting up their food production too early, then when a freeze returns it would kill the leaves destroying the trees' food source and the trees would die. Throwing its leaves off and growing new ones in the spring avoids the possibility.

Is leaves decay physical change or chemical change?
chemical change
Which living things cause leaves to decay?
insects, bacteria and fungus... micro-organisms.
What is a radioactive decay equation?
Gamma is not a decay process. It is a consequence of a decay process, but it, in itself, is not a decay process. It is the emission of a photon from the excited state of the nucleus in response to a decay process such as alpha or beta that changes the nucleus and leaves it with excess energy.
Is leaf rotting a physical change?
The decay of organic matter such as leaves is a chemical change.
Is decay of fallen leaves physical change?
Chemical, I belive; after such a decomposition, the plant can't return to its original form.
Why The leaves decay more quickly in summer than in winter?
Because of the warmer tempatures decay is mostly a chemical reaction and all chemical reactions are accellerated by warmer temps
Why do the leave decay more in the winter than the summer?
Because of the warmer tempatures decay is mostly a chemical reaction and all chemical reactions are accellerated by warmer temps
What is the mnemonic for remembering the seasons in order?
In order to remember the order of the seasons it is best to understand why we have seasons and when they occur. Spring Equinox 21st March: Summer Solstice 21st June Autumn Equinox 21-23rd September Winter Solstice 21st December Therefore the best mnemonics practice would be to associate a season to what occurs in nature and the cycle of renewal. Spring - Birth: Renewal of plants Summer - Life: Plants are fully bloomed (photosynthesis) Autumn - Decay: Leaves start to decay Winter - Death: Less sun means no leaves If you are teaching children a good way is to also use the clock face as a metaphor using their arms. Spring - 9PM Summer - 12PM Autumn - 3PM Winter - 6PM
Do organisms decay quickly in a desert?
Most organisms that die are quickly devoured by scavengers in the desert and do not have the opportunity to decay.
What would happen to trees if their leaves did not fall off before winter?
They would use up much more energy to keep the leaves sustained and would start to die, also the soil wouldn't get the nutrients from the annual decay of leaves and the soil quality would drop.
Why do leaves decay quicker in summer?
The temperature is higher, meaning that the decomposers can decay at faster rates. Their enzymes can work at a faster rate to decompose the detritus. To low a temp. and the rate of enzymes will slow down too much but too hot and the decomposers will be killed.
Do fallen leaves decay very slowly in the rainforest?
Fallen leaves would decay very rapidly in the rainforest because of its favourable temperature and abundance of microorganisms. In contrast, fallen leaves would decay very slowly in regions that are cold and sparsely populated by even bacteria such as the tundra.
What are the characteristic of rubber tire or other things that not decay?
Things that don't decay (or that don't decay quickly) are difficult to digest, for bacteria.
Do leaves rot?
Leaves rot due to decomposition. It is the natural process of a life cycle and the decay of the leaves is carried out by bacteria and fungi.
Why do dead organisms decay quicker in the summer?
extra heat during the summer causes faster decaying
Is leaves decay physical change or chemical change?
chemical change
Why do grass cuttings decay faster in summer than in winter?
a plant needs photosynthesis to grow.and to do the photosynthesis process it needs sunlight and in winter there is not much sunlight..this is how plants get food ..i think that's the reason..hope this helped.. :) Close, but not close enough. Below is a more "scientific" answer. The temperature during the summer is warmer, and therefore much more suitable for the grass to grow than during the winter. During the winter, temperatures drop to 32 degrees Fahrenheit, which is the freezing point of water, or even lower than that. With the water in the blades of grass frozen, the grass cannot get the nutrients it requires to thrive, and thus dies.
