Answers
Explanation:
A
We should conserve biodiversity because it is very important for all living organisms and for the environment. We should conserve biodiversity to save it from becoming extinct.
B
The protected forests are not also safe completely for wildlife because the poaching takes place at large scale in these areas. The poachers kill wild animals in those protected areas.
C
Some tribals depend on jungles , because jungle provides them every commodity they need to live. They Fetch fresh water from the jungle, collect fruits and vegetables , and also hunt the animals living in jungle. The houses in which they live are all made up of things taken from jungle.
D
One of the consequences of deforestation is a loss of biodiversity. Deforestation also increases greenhouse gas emissions, disrupts the water cycle, increases soil erosion and decreases the natural beauty of an area.
E
The Red Data Book is the state document established for documenting rare and endangered species of animals, plants and fungi as well as some local sub-species that exist within the territory of the state or country.
F
The definition of a migration is a movement to another place, often of a large group of people or animals. An example of migration is geese flying south for the winter.
Explanation:
ANSWER IS HERE:-
(A) Biodiversity provides numerous direct and indirect services to human beings. The diversity of plants and animals produced a vast variety of food and fabrics.
(B) The protected forests are not also safe completely for wildlife because the poaching takes place at large scale in these areas. The poachers kill wild animals in those protected areas.
(C) Some tribals depend on the jungle because they provide them with shelter, food and other requirements like herbs and so many things which are useful for them.
(D) Deforestation refers to the removal of trees resulting in cleared land.
There are several consequences of deforestation:
1. Changes in Soil:
Loss of nutrients in the soil that are derived from breakdown of tree leaves.
Increased soil erosion by wind and rain.
Increased flooding due to a lack of water absorption by trees.
Decreased ability to support other plants due to nutrient loss.
2. Loss of biodiversity:
Animals and plants that are unable to grow outside of a forest environment face extinction.
(E) Red Data Book is a state document established for documenting rare and endangered species of animals, plants, and fungi, as well as some local subspecies that exist within the territory. The Red Data Book contains the complete list of threatened species. The red data book helps us in providing complete information for research, studies and also for monitoring the programs on rare and endangered species and their habits. This book is mainly created to protect those species, which are on the verge of extinction, lost, harmed or not able to continue their life cycle. These species can either be animals, birds or plants.
(F) Migration is the movement of people across regions and territories. Migration can be internal and international. Internal migration occurs within the country and international migration occurs between the countries.
Internal migration does not change the size of the population but influences the distribution of population within the nation. Migration plays an important role in changing the composition and distribution of population.
