Which of the following characteristics does not make a species vulnerable to extinction?
1. | a large body size |
2. | small population size and low reproductive rates |
3. | feeding at a lower trophic level in the food chain |
4. | fixed migratory route and habitat |
A taxon is considered “critically endangered” if it faces a high risk of extinction in the wild in:
1. | immediate future | 2. | near future |
3. | medium-term future | 4. | distant future |
The first National Park established in India, the place where project tiger was started in 1972, is in:
1. | Madhya Pradesh | 2. | Kerala |
3. | West Bengal | 4. | Uttarakhand |
MAB stands for:
1. Marine Algal Biology
2. Manmade Air Banks
3. Man and Biosphere
4. Mother and Baby welfare scheme
In a biosphere reserve, active cooperation with local people is established in the:
1. | Natural zone | 2. | Core zone |
3. | Buffer zone | 4. | Transition zone |
The most effective means of conservation is to:
1. remove predators
2. preserve habitats
3. vaccinate against diseases
4. census the species during the breeding season
Species most vulnerable to extinction from human activities are those with:
1. low carrying capacities
2. high population growth rates
3. large niches
4. many natural predators
Agricultural biodiversity is conserved:
1. | in ex-situ locations commonly in the form of gene banks |
2. | in ex-situ locations commonly in botanical gardens |
3. | in in-situ locations such as biosphere reserves |
4. | in in-situ locations in agricultural institute fields |
The reasons to store seeds in a seed bank include all except:
1. | To have available the genes that plant breeders need to increase yield, disease resistance, drought tolerance, nutritional quality, taste, etc. of crops. |
2. | To forestall loss of genetic diversity in rare plant species in an effort to conserve biodiversity ex-situ. |
3. | To preserve the historical and cultural value of plants not grown now. |
4. | To guard against biopiracy by limiting the use of seeds only in certain areas. |
Recalcitrant seeds are:
1. | seeds that do not survive drying and freezing during ex-situ conservation |
2. | seeds that can resist the effects of drying or temperatures less than 10 °C |
3. | can be stored for long periods |
4. | terminator seeds |
