A population in a habitat with limited resources shows four phases of growth.
Identify the correct sequence of growth.

A Acceleration \(\rightarrow\) deceleration \(\rightarrow\) Lag phase \(\rightarrow\) asymptote
B Lag phase \(\rightarrow\) acceleration \(\rightarrow\) deceleration \(\longrightarrow\) asymptote
C Lag phase \(\rightarrow\) asymptote \(\rightarrow\) deceleration \(\rightarrow\) Acceleration \(\rightarrow\) lag phase
D Acceleration \(\rightarrow\) lag phase \(\rightarrow\) deceleration \(\rightarrow\) asymptote

Verified Solution

Answer & Solution

Correct Answer

(B) Lag phase \(\rightarrow\) acceleration \(\rightarrow\) deceleration \(\longrightarrow\) asymptote

Step-by-step Solution

Detailed explanation

A population growing in a habitat with limited resources show initially a lag phase, followed by phases of acceleration and deceleration and finally an asymptote, when the population density reaches the carrying capacity

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
