Carrying Capacity |Growth Models |Population Interaction |Adaptation-Parasite & Its Types |OMR

Carrying capacity of a population is determined by :

Population Interaction|Mutualism|Commensalism|Parasitism|Predation

Define the term population interactions. State its two types

(a) Write an equation for Verhulst Pearl logistic . Growth where N = Population density at a time t r = Intrinsic rate of natural increase K = Carrying capacity (b) Draw a graph for a population whose population density has reached the carrying capacity . (c) Why is the logistic growth model considered a more reallistic one for most animal populations ? (d) Draw a growth curve where resources are not limiting to growth of a population.

When population reaches carrying capacity :

When the carrying capacity is equal to the population size, the net rate of increase in the population equals

Types of interaction that occur in predation and parasitism are
