How are the wild animals affected by cutting of forest?

  1. Number decreases

  2. Color of skin will be affected

  3. Ability of homeostasis will decrease

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Seventy percent of the world's plants and animals live in forests and are losing their habitats to deforestation (cutting of forest), Loss of habitat can lead to species extinction. The number of wild animals decreases by cutting of forest because If the trees are gone, birds, reptiles, and insects lose their homes and food sources. That will affect the small mammals, which are a food source for mid- and large-sized mammals. It is a cascade effect that leads to species extinction. So, the correct answer is 'Number decreases'.

Which of these is not a sustainable agriculture technique?

  1. Mixed farming

  2. Slash and burn farming

  3. Crop rotation

  4. Crop selection
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Sustainable agriculture is the method of growing crops by using the technique without harming the environment. Slash and burn farming is not a sustainable agriculture technique as they increase the air pollution by release a large amount of carbon dioxide.

So, the correct answer is option B.

Multiple choice evs - i the environment and us pollution of soil degradation of land damaging the forests

The natural disasters that can affect habitats in the environment are

  1. Droughts

  2. Floods

  3. Thinning of ozone

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Drought and floods both are the natural disasters in which there is the extreme scarcity of water due to the absence of rainfall and floods due to heavy rainfall. Drought results in infertile agricultural lands due to nonavailability of water for crop production. Hence there is no food and water for the organisms in that area that results in either migration of organisms or their death. Flood makes soli saline and erodes the fertile soil that affects the crop production even it damages the flora, fauna and other infrastructure. Thus, the correct answer is option D.

Multiple choice evs - i the environment and us pollution of soil degradation of land damaging the forests

Which of the following is an effect of deforestation?

  1. Water pollution

  2. Greenhouse effect

  3. Outbreak of diseases

  4. Extinction of aquatic life
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

If deforestation is performed, there will be no trees so, the amount of the greenhouse gasses will increase in the atmosphere. These greenhouse gasses trap heat from the infrared radiation in the atmosphere and increases the atmosphere's temperature i.e, global warming. 

Thus, the correct answer is option B. 

Multiple choice zoology soil pollution pollution of soil degradation of land damaging the forests

All of these are a result of land degradation except 

  1. Soil erosion

  2. Extinction of plant species

  3. Endangered animals

  4. Clear cutting forests

  5. Ozone depletion
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Land degradation is the loss in quality of natural land areas due to pollution.
A. Due to land degradation, there is deterioration in soil structure due to which soil particles can't bind to each other tightly. Hence there is soil erosion i.e. removal of upper fertile layer of soil due to flood, wind or any other natural calamity.
B. Due to land degradation, many plant species have become extinct because there is loss of soil nutrients which are essential for plants growth.
C. Animals are getting endangered as their habitat is also being lost due to land degradation.
D. Clear cutting of forests doesn't occur due to land degradation. It's the activity of mankind.
E. Ozone layer depletion occurs due to the halo compounds that are released from the degrading land.
Hence, clear cutting forests is not the result of land degradation.
So, the correct answer is 'Clear cutting forests'.
Multiple choice evs - i the environment and us pollution of soil degradation of land damaging the forests

Which of the following is/are caused due to deforestation?

  1. Soil erosion

  2. Depletion of water in the catchment areas

  3. Global warming

  4. All of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Deforestation is the process of cutting or removal of forest to fulfill the need of the population. It has many negative impacts on the environment such as loss of species, soil erosion and reduces rainfall. The tree absorbs water from soil for photosynthesis and produces water vapor that is released into the atmosphere which in turn causes rainfall. If there will be less number of the tree then rainfall will also decrease. Plants absorb carbon dioxide (greenhouse gas) for photosynthesis and releases oxygen. Greenhouse gases absorbs the solar energy and increase the earth's temperature is called as global warming. Thus, the correct answer is option D.
