Question 42 Marks

Climate has a profound effect on ecology.

Answer

Climate has a profound and far-reaching effect on the ecosystem.
Temperature and humidity are the two most active functions of these two climatic elements.
So those two are more important.
Rainfall is also an important factor affecting the ecosystem.
Organisms can grow and develop only within a certain range of temperature.
Nature has set extremes for different animals, plants, and humans.
More or less temperatures destroy the ecosystem.
Polar bears are accustomed to tolerating much colder than humans.
To escape the extreme cold, many birds and animals leave their native place or homeland in winter and migrate temporarily to milder or less cold regions.
Migratory birds come from Siberia as far away as winter in Nal Sarovar and some other areas.
Temperature or climate is an important factor for the survival of an organism.
Thus, climate has a profound effect on ecology.

Some animals are useful for farming, transportation or transportation.
Bird eggs, masses, colored feathers are found.
Silkworm by silkworms, honey by bees and various fish shapes, useful for medicine.
Micro-organisms like earthworms help in fertilizing the soil.
According to Hutchinson, "the part of the earth where life is possible is called the biosphere."
That is, life exists in the part of the aquifer, atmosphere, and solid that covers the ecosystem.
This is called "bioavailability".
