प्रश्न
Observe the graph and select the correct option:
विकल्प
Line A represents, S = CA2
Line B represents, log C = log A + Z log S
Line A represents, S = CAZ
Line B represents, log S = log Z + C log A

उत्तर
Line A represents, S = CAZ
Explanation:
The equation S = CAZ often gives the species-area relationship, where S is the number of species, A is the area, and C and Z are constants. The relationship is typically nonlinear.

Short answer type question
Tropical regions exhibit species richness as compared to polar regions. Justify.
On a log scale the relationship of species richness and area becomes linear (straight line) and is given by the equation.
In the equation: log S = log C + Z log A , S= species richness; Z = slope of line (regression coefficient); A = area; C = Y intercept. For smaller area, the value of Z ranges from ____________.
Species richness - area relationship is given by ______.
Amongst the animal group given below, which one has the highest percentage of endangered species?
The pattern of biodiversity is affected by ______.
Which of the following hypothesis suggests that ecosystems are like aeroplanes where flight safety (ecosystem functioning) may or may not be compromised, depending upon which species are being lost?
Tropical regions show greatest level of species richness because -
- Tropical latitudes have remained relatively undisturbed for millions of years, hence more time was available for species diversification.
- Tropical environments are more seasonal.
- More solar energy is available in tropics.
- Constant environments promote niche specialization.
- Tropical environments are constant and predictable.
