NEET BIOLOGY

Detailed explanation-1: -Growth depends upon three factors – initial size (W0), rate of growth (r) and the time interval for which the rate of growth can be retained.

Detailed explanation-2: -When the per capita rate of increase ( r) takes the same positive value regardless of the population size, then we get exponential growth. When the per capita rate of increase ( r) decreases as the population increases towards a maximum limit, then we get logistic growth.

Detailed explanation-3: -Food, nutrients, water, oxygen, optimum temperature, optimum light, minerals, gravity, etc. are the factors that can influence growth.

Detailed explanation-4: -In these simple models of exponential growth, birth and death rates stay the same through time, regardless of population size. They are density-independent.

Detailed explanation-5: -Exponential growth of plants is expressed with equation, Wt=Woert. In this equation ‘e’ represents. No worries!
