Biology Question Bank for Entrance Exams

For AIPMT Main other Medical Entrance Exam Prepration, Question Bank for Biology Biodiversity and its Conservation is given below.
IMPORTANT POINTS

Biodiversity refers to the variety of microbes, plants and animals of an area. It is the degree of variety in nature. It is the totality of genes, species and ecosystem. Thus it can be defined as the variety and variability of life. There is lot of variations amongst organisms. There can be genetic variations, species variations as well as ecosystem variation. On the basis of it, there are three levels of biodiversity

AIPMT Question Bank: Biology - Biodiversity and its Conservation

Knowledge of biodiversity is important for systematic study of organisms, ecosystem studies and biogeograpy studies etc. It provides food, marketable, items etc. It has social and aesthetic value. Information of biodiversity at world level national level and state level is important. The man causes of biodiversity loss are :

1. Habitat loss and fragmentation

2. over-exploitation

3. Alien species invasions and 4. co-extinctions

conservation of biodiversity means the conservation of gene complexes, species and ecosystem, Biodiversity is essential to global food security and nutrition. The conservation of biodiversity are of two types: 1. In-situ conservation and 2. Ex-situ conservation. In-situ conservation is possible through to declare protected areas, biosphere reserves, national parks and sanctuaries. Ex-situ conservation can be done through botanical gardens, zoos, gene bank, pollen bank, seed bank, tissue culture and cryopreservation.
