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. | 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 |
In the following questions a statement of assertion (A) is followed by a statement of reason (R).
Assertion(A): | Sacred forests are refuge of rare, endangered and endemic taxa. |
Reason(R): | The land of sacred forests is fertile. |
1. | Both (A) & (R) are true and (R) is the correct explanation of (A) |
2. | Both (A) & (R) are true but (R) is not the correct explanation of (A) |
3. | (A) is true statement but (R) is false. |
4. | Both (A) and (R) are false statements. |
Statements I: | Species confined to a particular region and are not found anywhere else are called endemic species |
Statement II: | Keystone species are usually abundant in an ecosystem |
