____ are not examples of the biological resources provided by biodiversity.
____ can immediately cause mass loss of biodiversity.
Habitat loss can immediately cause mass loss of biodiversity. Actually, habitat loss is directly connected to loss of biodiversity. If we cut down trees in a square meter area, the species that live in that particular area do not have any place to live (loss of habitat). Thus the plant species is lost in that area and the animals that depend on the plants and trees for their survival either die or migrate to another place, leaving the place without any life forms. Pollution, high temperatures and hunting are long-term processes that contribute to loss of biodiversity.
Which of the following is the main factor of desertification?
Desertification is the process leading to the formation of desert. The main factor of desertification of land is over-grazing by herbivorous animals.
____ is a cold spot species.
Penguin is a cold spot species. A cold spot is a region with low species diversity. The species that are found in the cold spots are unique to that region. You can find penguins only in Antarctica and in certain cold regions of the world. However, you can find a python, a peacock or a monkey in many regions of the world.
Biodiversity of a geographical region represents
Biodiversity is the number of variety of organism found within a specified geographic region.
Water is a resource
Water is a renewable resource but can become non renewable if they are not used properly.
Much of the terrestrial diversity is found in ____.
Much of the terrestrial diversity is found in tropical forests. Tropical forests support a variety of species. Most of the flora and fauna are found in the tropical forests. Taiga, desert and grasslands support less biodiversity than the tropical forests.
Which is preserved in national park?
The World Biodiversity Day is celebrated on ____ of every year.
The world biodiversity day is celebrated on 22nd May of every year.The United Nations proclaimed May 22 to be the International Day for Biological Diversity (IDB). This is to increase the understanding and awareness of biodiversity issues by the people around the world.
____ is an unusual habitat for species diversity.
Hydrothermal vent is an unusual habitat for species diversity. Hydrothermal vents are the habitats, which have high temperatures (above 45°C), which is not an ideal place for an organism to live. However, some bacteria are found to survive in these unusual habitats.
Soil conservation is
Soil conservation is to conserve fertile soil from the losses like, heavy rainfall, drainage, high wind, flood, drought etc.
Which of the following animal has become almost extinct in India?
Endemic plants are those which are
Species restricted to small area are called endemic.
Wild life comprises all the living organisms in their natural habitats which are neither cultivated nor tamed.
The most biodiversity rich zone in India
Largest region is deccan, peninsula and most biodiversity rich region is western ghats (4%) with a very large number of endemic amphibian species.
The species which are very few in number (naturally) in the world are known as
Rare species are species with naturally small population, either localised or thinly scattered.
The correctly matched pair of an endangered animal and a national park is ____.
The correctly matched pair of an endangered animal and a national park is Lion : Gir Wildlife Sanctuary.Gir Wildlife Sanctuary is a well-known national park in Gujarat that protects lions in India.
One of the social benefits that we get from a healthy biodiversity is ____.
One of the social benefits that we get from a healthy biodiversity is cultural value. Protection of water resources, soil protection and pollution breakdown are some of the ecosystem services provided by biodiversity.
The most effective way to conserve the plant diversity of an area is ____.
The most effective way to conserve the plant diversity of an area is by creating biosphere reserve.A biosphere reserve is land or water area, which is protected by the government to conserve ecosystems. Biosphere reserves help us to protect the biological diversity of plants and animal species. They make sure that the plant and animal species are safe from the human impact.
A collection of plants and seeds having diverse alleles of all the genes of a crop is called
Gene library contains DNA fragments representing the entire genome of an organism. So collection of alleles of the genes of a crop is called gene library.
"Chipko movement" is concerned with
"Chipko movement" is concerned with plant conservation.
Deforestation does not lead to
Deforestation causes the depletion of wood and nutrients from an ecosystem and hence nutrient cycling gets slowed down.
____ is the most important strategic plan to protect biodiversity.
Preserving global biodiversity is the most important strategic plan to protect biodiversity. Conservation biology is a strategic plan to protect biodiversity. Preserving global biodiversity includes engaging public policy and concerns affecting local, regional and global scales of communities, ecosystems, and cultures.
The ____ in India supports only a limited biodiversity.
The Thar desert in India supports only a limited biodiversity. The climatic conditions of the Thar desert are extreme. That is why it supports a limited number of species than the Eastern Himalayas, the Western Ghats and the Sunderbans, which have favorable climatic conditions to support a large number of species.
____ is NOT a latitudinal gradient that influences the pattern of biodiversity.
Elevation is NOT a latitudinal gradient that influences the pattern of biodiversity. Average temperature, precipitation and annual net productivity are some of the latitudinal gradients that affect biodiversity patterns in an area. Whereas, elevation is an altitude gradient that affects biodiversity patterns in an area.
The phenomenon, which does not support the increase in biodiversity is ____ .
The phenomenon, which does not support the increase in biodiversity is mass extinction. Mass extinction is an abnormal event where there is a huge loss in world's biota. This leads to the extinction of all parts of life on the Earth. So, there is no chance of increase in biodiversity for a long period of time. Also, there is no possibility of regaining the extinct species on the Earth.
Those species whose populations have been seriously depleted and whose ultimate security is not assured are known as
Those species whose populations have been seriously depleted and whose ultimate security is not assured are known as endangered species.
Alpha diversity is present
Alpha diversity is present within community.
If the forest cover is reduced to half, what is most likely to happen on a long term basis?
If the forest cover is reduced to half, large areas will become deserts.
