Original practice preview

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

Example 1 · difficulty 2/5

In the Verhulst–Pearl logistic growth equation dN/dt = rN[(K − N)/K], the symbol K stands for:

A. The intrinsic rate of natural increase
B. The maximum reproductive potential under ideal conditions
C. The fraction of resources still unused by the population
D. The carrying capacity, i.e. the maximum population size the environment can sustain

Example 2 · difficulty 3/5

Thermoregulation is considered energetically very expensive for tiny mammals such as shrews and hummingbirds. The correct reason is that these animals:

A. Possess dense fur that traps excessive metabolic heat
B. Have a large surface area relative to their body volume, so they lose heat rapidly and must metabolise continuously
C. Are thermal conformers and therefore cannot produce any metabolic heat
D. Remain dormant through most of the year to conserve energy

Example 3 · difficulty 2/5

An orchid plant grows anchored on the branch of a mango tree, gaining access to light and support while the mango tree shows no measurable gain or loss. The interspecific interaction between the two is:

A. Parasitism
B. Mutualism
C. Commensalism
D. Amensalism

Frequently asked questions

Are these official NEET 2022 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 2022 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.
