In ecology, ‘growth’ can refer to the development of an individual organism or to the size of an entire population. Both categories of growth are complex because they depend upon a multiplicity of factors such as nutrition, predators, competitors, disease, toxins, resources, temperature, humidity, etc. Each of these factors is infinitely variable.
