Question 33 Marks

Write a short note about Biochemical cycles

Answer

Plants absorb inorganic or chemical elements through their roots. And converts it into biological elements.

These biological elements are transferred to different organisms through the food chain.

With the death of these organisms, the biological element is again converted into inorganic or chemical elements.

The process of change in the biological state of inorganic elements or chemical elements as well as their return to this biological form is called biogeochemical cycle.

The water cycle, carbon cycle, oxygen cycle, nitrogen cycle, phosphorus cycle, rock cycle, etc. are studied in biogeochemical cycles.

Here we will study the nitrogen cycle, the oxygen cycle, and the carbon cycle.

Question 43 Marks

Explain ecological imbalance and its consequences.

Answer

Naturally biochemical cycles, energy flow arrangements are arranged in a very precise manner.
It also undergoes necessary changes from time to time.
Any living thing lives according to this arrangement of nature.
It does not directly interfere with physical or biological factors.
Man has been able to establish habitation, mining, industries, transport routes in regions where his thinking power can be used.
Thus, direct human intervention in the natural cycles has created the Panama Canal, damaging marine ecosystems.
The construction of a cricket ground in Sharjah has affected the desert's ecosystem.
Human needs are increasing due to population explosion.
Human beings are expanding their residential and industrial areas using the progress made in the field of technology.
As a result, wildlife habitat is lost or their area is reduced or even destroyed.
Deforestation for fuel and timber, hunting wild animals for leather, bone or mass.
Musk deer are killed to get musk, rhinos to get horns and elephants to get ivory.
In addition, many other animals are killed haphazardly for a variety of reasons. This is a sad thing.
In addition, indiscriminate use of grazing lands reduces the diversity and abundance of herbivores and non-herbivorous wildlife.
Each organism has the ability to adapt to a changing environment in general.
But very quickly and unnaturally, that is, because of the rapid changes in man-made environment, wildlife cannot adapt and perish.
The task of conserving life is not just a government job.
Legislation alone will not make this work a success.
For this, if the guidance and encouragement of wildlife and nature lovers congregations are formed from the right place, such congregations will be very useful.
Many such congregation organizations in our country are working for wildlife.
Government as well as non-government help is available in this work.

Explain briefly about biodiversity.

Answer

Every animal and plant on earth is very different from any other animal or plant.
The earth is home to an unimaginable variety of species, sizes, shapes and colors of animals, human beings, plants and micro-organisms.
Its number and life cycle have a special kind of balance in the ecosystem.
The diversity found in organisms is called biodiversity.
The term "biodiversity" refers to the diversity in the living forms of flora and fauna.
India is one of the $12$ countries in the world that is considered to be the most diverse god in terms of biodiversity.
The following are the $10$ biogeographic zones identified in India.

$(1)$ Trench Himalayas $(2)$ Himalayas $(3)$ Indian Desert $(4)$ Semi-arid region $(5)$ Western Ghats $(6)$ Southern Peninsula $(7)$ Gangetic plains $(8)$ North East India $(9)$ Islands $(10)$ Coastal regions .

Out of the above $10$ types of biogeographic regions, four geographical regions are desert region, semi-arid region, western ghat region, coastal region located in Gujarat.

Question 63 Marks

Write a short note about the mulch.

Answer

This upper layer of the earth is also called the crust.
Whose notebook matters are as follows:
This earth's crust is also called Bhukvach, which is made up of clay and rock layers.
The average thickness of this cover is $33\ km.$
While in mountainous areas its average thickness is $35$ to $50\ km.$ Is equal to.
In this mantle lies a thin layer of rocky rocks near the surface of the earth.
This cover is also called "fox".
In which "SI" means silica and "AL" means aluminum.
Taking the first two English letters of both minerals, this cover is known as "SIAL".
The layer below the "seal" is called the SIMA "boundary".
In which "SI" means serosilica and "MA" means magnesium, resulting in a layer of "boundary" beneath the seal.
The cube consists of basalt rocks on the surface and granite rocks in the lower layers.
At the time of a volcanic eruption, hot magma comes to the surface from this boundary layer.
The continents are mostly made up of "seals".
The "silicon" mineral is common in the structure of the "seal" and the "boundary" of the two sections of this coating.
