2. Population explosion
3. Competition
4. Biodiversity loss
| 1. | Cryopreservation | 2. | In vitro fertilization |
| 3. | National Parks | 4. | Micropropagation |
1. Conserve only extinct species
2. Protect and conserve the whole ecosystem
3. Conserve only high risk species
4. Conserve only endangered species
Which of the following come under the "Evil Quarter"?
(a) Habitat loss and fragmentation
(b) Over-exploitation
(c) Alien species invasion
(d) Mortality
(e) Competition
Choose the correct answer from the options given below:
| 1. | (a), (c) and (d) | 2. | (b), (c) and (d) |
| 3. | (a), (b) and (c) | 4. | (a), (b) and (d) |
Species Area relationship is described by the following equation.
log S = log C + Z log A
where Z is:
1. Area
2. Species richness
3. Slope of the line
4. Y-intercept
Endemism refers to:
1. Species richness
2. Species evenness
3. Species confined to that region
4. Species diversity
1. Humans are ethically responsible for protecting endangered species.
2. Scientists have finally identified most of the species on Earth and are thcurreus able to quantify the number of species becoming extinct.
3. The current rate of extinction is high and human activities threaten biodiversity at all levels.
4. Humans have greater medical needs than at any other time in history, and many potential medicinal compounds are being lost as plant species become extinct.
1. mammals
2. birds
3. fish
4. amphibians
1. increase in global warming and thinning of the ozone layer
2. potential loss of ecosystem services on which people depend
3. increase in the abundance and diversity of edge-adapted species
4. loss of source of genetic diversity to preserve endangered species
