Tag: biodiversity loss and need for conservation

When there are no more individuals of a species (plant or animal) alive anywhere in the world, the species is said to be extinct. Extinction is also known as the process of dying out. The process is a completely natural part of evolution. But sometimes extinctions happen at a higher and a faster rate than usual. Factors such as large body size, small population and position at a higher trophic level favour extinction.

When there are no more individuals of a species (plant or animal) alive anywhere in the world, the species is said to be extinct. A decrease in the species diversity progresses to extinction if left uncontrolled. Extinction is also known as the process of dying out. The process is a completely natural part of evolution. But sometimes extinctions happen at a higher and a faster rate than usual. Factors such as over-exploitation, large body size, small population, massive habitat loss and position at a higher trophic level favor extinction. A plant podophyllum is at the verge of extinction due to over-exploitation. So, the correct answer is 'Podophyllum'.

When there are no more individuals of a species (plant or animal) alive anywhere in the world, the species is said to be extinct. Extinction is also known as the process of dying out. The process is a completely natural part of evolution. But sometimes extinctions happen at a higher and a faster rate than usual. Factors such as large body size, small population, massive habitat loss and position at a higher trophic level favor extinction. As forests are the main habitat for the wild animals, their loss favors the extinction of the same.

Biodiversity loss leads to the extinction of species. Factors such as habitat loss and fragmentation, over-exploitation, alien species invasion and co-extinction are causes for such losses. When there are no more individuals of a species (plant or animal) alive anywhere in the world, the species is said to be extinct. Extinction is also known as the process of dying out. The process is a completely natural part of evolution.
So, the correct answer is 'Biodiversity loss'.

Jhum cultivation, also known as the slash and burn agriculture, is the process of growing crops by first clearing the land of forests and burning them thereafter. It is also known as shifting agriculture. The burnt soil contains potash which helps in increasing the nutrient content of the soil. This process has led to the maximum damage to the Indian forests as they are cleared for this process.

Endangered species are prone to become extinct. When there are no more individuals of a species (plant or animal) alive anywhere in the world, the species is said to be extinct. Extinction is also known as the process of dying out. The process is a completely natural part of evolution. But sometimes extinctions happen at a higher and a faster rate than usual. Factors such as large body size, small population, massive habitat loss and position at a higher trophic level favor extinction. As forests are the main habitat for the wild animals, their loss favors the extinction of the same.

Habitat destruction, poaching, climate change and lack of resource management have resulted in a decline in biodiversity by leading to the extinction of species. Other factors such as large body size, small population, and position at a higher trophic level also favor extinction of species. When there are no more individuals of a species (plant or animal) alive anywhere in the world, the species is said to be extinct. Extinction is also known as the process of dying out.

• When there are no more individuals of a species (plant or animal) alive anywhere in the world, the species is said to be extinct. Extinction is also known as the process of dying out. 
  
  
• The process is a completely natural part of evolution. But sometimes extinctions happen at a higher and a faster rate than usual. 
  
  
• Factors such as large body size, habitat loss, and fragmentation (a most important factor), small population and position at a higher trophic level favor extinction.
  
  

Smaller population faces more risk of extinction than larger population. Smaller population faces more random fluctuation, which may result in greater death rate than birth rate and that ultimately leads to their extinction. Moreover, in smaller population, more inbreeding occurs between the individuals of a population, that leads to decrease in population's potential by letting the expression of harmful mutations through heterozygosity. In smaller population, amount of accumulated variation is lesser than in larger population. Variation help in survival of population under changed environmental conditions.

Wildlife is an asset for our environment. It needs to be protected to maintain an optimum biodiversity. Some of the reasons for extinction of wild life are:
