Question

The following diagram represents the population growth curves of two different species, A and B, living together in an area. Answer the following questions based on it.

1. What type of growth patterns are exhibited by species A and B?
2. Give mathematically equations to represent the growth curves of species A and species B separately.
3. In the diagram, what does the horizontal line K represent?

Answer 1

i. Species A = Exponential growth, Species B = Logistic growth

ii. A = `(dN)/(dt) = rN`, B = `(dN)/(dt) = rN((K - N)/K)`

iii. K represents carrying capacity.
