1. The equation of Verhulst-Pearl logistic growth is -
\(\displaystyle \frac{\text{dN}}{\text{dt}}\,=\,\text{rN}\left[\frac{\text{K}-\text{N}}{\text{K}}\right]\)
From this equation, K indicates:

(1).Carrying capacity

(2). Population density

(3). Intrinsic rate of natural increase

(4). Biotic potential

2. Given below are two statements :
Statement I: Gause’s competitive exclusion principle states that two closely related species competing for different resources cannot exist indefinitely.
Statement II: According to Gause’s principle, during competition, the inferior will be eliminated. This may be true if resources are limiting.
In the light of the above statements, choose the correct answer from the options given below:

(1).Statement I is true but Statement II is false.

(2). Statement I is false but Statement II is true.

(3). Both Statement I and Statement II are true.

(4). Both Statement I and Statement II are false.
