Population Growth
R and K Selection
R and K selection are concepts in ecology used to describe traits in the fluctuation of a population or population dynamics. For example, they describe the life-association traits between parent and offspring, such as quantity or number of young ones born at a time, quality of parental care, the age to maturity, and reproductive effort.
looking at ecological models to describe population phenomena. , and describing the flaws of these models. If the models don’t accurately reflect reality, why do we spend so much time on them?
Ecological modeling is the analysis of mathematical models of ecological processes. It includes purely biological and combined biophysical models. The models are analytic and are used to learn the complex ecological processes and predict changes in real ecosystems.
The drawbacks of the models related to population includes:
The main drawback of the growth models is they are based on unrealistic and unscientific assumptions.
The flaws of these models include the Natural Growth Rate that is open to Objection. L.B. Yeager criticized the concept of natural growth rate in Harrod’s model.
The varieties of variables are used in Harrod and Domar models are non-monetary in character.
The Harrod-Domar models lay undue emphasis on the economic parameters only.
