Extent of global diversity of invertebrates is shown in the pie diagram below. Choose the most appropriate alternative that the four portions (a-d) represent.

Which of the following hypothesis states: Rich species diversity leads to lesser variation in biomass production over a period of time.
With reference to graph select the correct alternative
Which of the following is an observation of Alexander von Humboldt's documented pattern in ecology?
Select the correct alternative for x and y.

Amongst the animal group given below, which one has the highest percentage of endangered species?
Which of the below mentioned regions exhibit lees seasonal variations?
Which of these is true about tropical environments?
The pattern of biodiversity is affected by ______.
Species diversity decreases as we move away from the equator towards the poles. What could be the possible reasons?
Write the inference drawn by Alexander von Humboldt after his extensive explorations of South American jungle.
Study the graph given below:

As per Alexander von Humboldt, what do the symbols S, A, Z and C in the graph stand for, in respect of a species and area relationship?
The species-area relationship is represented on a log scale as ______.
Who observed that within a region, species richness increased with increasing explored area, to a certain limit?
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.
Choose the correct answer form the options given below:
Which of the following characteristics are seen in a stable community?
- It is strong enough to withstand environmental disturbance and recovers quickly.
- It is resistant to invasive species.
- It exhibits constant change in biomass production over a period of time.
- It has more species diversity.
What does the variable S represent in the species-area formula log S = log C + Z log A?
