When does the growth rate of a population following the logistic model equal zero? The logistic model is given as dN/dt = rN(1-N/K)

(1) when N nears the carrying capacity of the habitat

(2) when N/K equals zero

(3) when death rate is greater than birth rate

(4) when N/K is exactly one

Gause's principle of competitive exclusion states that

1. Competition for the same resources excludes species having different food preferences
2. No two species can occupy the same niche indefinitely for the same limiting resources
3. Larger organisms exclude smaller ones through competition
4. More abundant species will exclude the less abundant species through competition
