Original practice preview

These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.

Example 1 · difficulty 1/5

Alexander von Humboldt observed that, within a region, species richness increases with increasing explored area, but only up to a limit. Which equation correctly expresses this species-area relationship, where S is species richness, A is area, and C and Z are constants?

A. S = C + ZA
B. log A = log S + Z log C
C. log S = log C + Z log A
D. S = C − Z log A

Example 2 · difficulty 3/5

In the species-area relationship log S = log C + Z log A, the regression coefficient Z is usually 0.1 to 0.2 for small islands (e.g., plants in Britain) but rises to 0.6 to 1.2 for vast continental tracts such as tropical forests. A very steep slope (high Z value) indicates that:

A. species richness climbs sharply with area, so even a moderate shrinkage of habitat eliminates a disproportionately large number of species
B. species richness stays practically unchanged as the sampled area increases
C. beyond a certain point, exploring additional area yields virtually no new species
D. the community is dominated by generalist species with very wide geographic ranges

Example 3 · difficulty 2/5

Species diversity generally decreases from the equator towards the poles. Evaluate the following proposed explanations for the greater biodiversity of the tropics: (i) Tropical environments, being less seasonal and more constant, promote niche specialisation; (ii) Temperate regions underwent repeated glaciations, giving them extra time for speciation; (iii) The tropics receive greater solar energy, supporting higher productivity. Which combination is correct?

A. (i) and (ii) only
B. (i) and (iii) only
C. (ii) and (iii) only
D. (i), (ii) and (iii)

Frequently asked questions

Are these official NEET 2016 Biology Ecology PYQs?

No. The previews are original NeetVellum practice questions. A historical item receives a PYQ label only after its official paper and authoritative final answer key are attached. Use the official archive for the source paper.

How should I use the NEET 2016 paper?

Solve the official paper under its original timing, verify against the final key, classify every miss, and then use the linked current-syllabus practice bank to repair the exposed concept.
