Original practice preview

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

Example 1 · difficulty 2/5

A. 950 g m⁻² yr⁻¹
B. 450 g m⁻² yr⁻¹
C. 280 g m⁻² yr⁻¹
D. 1750 g m⁻² yr⁻¹

Example 2 · difficulty 1/5

On a completely bare rock surface undergoing primary succession, the organisms that appear FIRST and begin the process of soil formation are:

A. Lichens
B. Mosses
C. Herbaceous plants
D. Small shrubs

Example 3 · difficulty 3/5

Which of the following correctly represents the sequence of steps generally described in the process of decomposition?

A. Humification → fragmentation → leaching → catabolism
B. Leaching → catabolism → fragmentation → humification
C. Fragmentation → humification → leaching → catabolism
D. Fragmentation → leaching → catabolism → humification

1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
2. Attempt closed-bookExpose the concept or execution gap before rereading.
3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions

Are these official NEET 2019 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 2019 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.
