Give three hypotheses for explaining why tropics show greatest levels of species richness.
Observe the graph and select the correct option:

Short answer type question
Tropical regions exhibit species richness as compared to polar regions. Justify.
Latitudinal and altitudinal gradient is shown by which of the following habitat(s)?
On a log scale the relationship of species richness and area becomes linear (straight line) and is given by the equation.
Maximum species richness is observed in the ______.
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 ____________.
Which of the following is an observation of Alexander von Humboldt's documented pattern in ecology?
Which of these is true about tropical environments?
"Species richness increased with increased explored area but only a limit". This statement was given by.
Is it true that there is more solar energy available in the tropics? Explain briefly.
The relation between species richness and area for a wide variety of taxa turns out to be a rectangular hyperbola. Give a brief explanation.
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?
Rivet Popper Hypothesis is an analogy to explain the significance of ______.
Who observed that within a region, species richness increased with increasing explored area, to a certain limit?
When pre-reproductive and post - reproductive age group is same in structure, the population is______.
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.
