Solution:

In the given graph, "a" is-Exponential growth curve and "b"-Logistic growth curve
- Logistic growth curve "b" is considered a more realistic one because the resources are finite and become limited sooner or later.
- $K$ stands for carrying capacity, which refers to the maximum number of individuals of a population that the given environment can sustain at a given time.
- N symbolises population density, i.e. the number of individuals of a species in a given population per unit area.
