State
whether the given statements are true or false. If true, write the
reasons.
(i)
Ganga−Brahmaputra plain of India is
an overpopulated region.
(ii)
Water availability per person in India is
declining.
(iii)
Rows of trees planted in the coastal areas
to check the wind movement is called intercropping.
(iv) Human
interference and changes of climate can maintain the ecosystem.

(i)
Ganga−Brahmaputra plain of India
is an overpopulated region.
This
statement is true.
Plains and river valleys offer suitable land for agriculture. Hence,
these are densely-populated areas of the world.
(ii)
Water availability per person in India
is declining.
This
statement is true.
Though water is present in abundance, fresh water is a scarce
resource. Water availability is a serious problem in many regions of
the world. Due to the wastage of water, deforestation, and the
pollution and depletion of fresh water reserves (such as rivers and
ground water), the availability of water is fast declining.
(iii)
Rows of trees planted in the coastal
areas to check the wind movement is called intercropping.
This
statement is false.
The described process is called shelter belts.
Intercropping
is the process in which different crops are grown in alternate rows,
and are sown at different times to protect the soil from rain wash.
(iv)
Human interference and changes of
climate can maintain the ecosystem.
This
statement is false.
Human interferences and climatic changes for the most part adversely
affect the balance of the ecosystem.
