Multiple choice

Which of the following is an advantage of in situ conservation?

  1. The population can lose much genetic diversity

  2. It facilitates scientific research

  3. It damages significant elements of cultural heritage

  4. Plants and animals are conserved in an artificial habitat
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In situ conservation involves protecting species in their natural habitat, which allows for natural ecological processes to continue and facilitates scientific research on species in their native environment.

Multiple choice zoology meaning of life level of biological organization in animals introduction to tissues basics of ecology

Natural habitats that were once large and connected have become more fragmented due to human activities. Wildlife corridors between the fragments of habitat are necessary to maintain wildlife habitat and natural areas.
Which of these is a benefit of wildlife corridors?
I.Allows young adult animals to access a new range.
II. Improves genetic fitness as adult animals interact with potential mates in other areas. 

III. Allows plants and animals to colonize new habitat as the climate changes.

  1. I only

  2. II only

  3. III only

  4. I and III only

  5. I, II and Ill
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Wildlife corridors are the areas that link wildlife habitats but are separated by human activities such as roads.
Hence, wildlife corridors between fragments of habitat will allow young adult animals to access a new range and allows plants and animals to colonize new habitat as the climate changes.
So, the correct answer is 'I and III only'.
Multiple choice evs whose forests? conservation of forest and wildlife wildlife deforestation and conservation

Why is conservation of forest important?

  1. It is the lung of earth

  2. It provides food

  3. It maintains ecosystem

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Option 'D' is correct
Conservation of forest is important because it is the lung of the earth.
It absorbs carbon dioxide during photosynthesis and produces oxygen as a by-product.
Forest provides food in the form of fruit, nut, berries, leaves, honey, fodder. It maintains ecosystem by balancing the oxygen, carbon dioxide in the atmosphere. It absorbs $CO _2$ and reduces the chances of global warming.
