WitrynaThe logistic model assumes that every individual within a population will have equal access to resources and, thus, an equal chance for survival. For plants, the amount of water, sunlight, nutrients, and space to grow are the important resources, whereas in animals, important resources include food, water, shelter, nesting space, and mates. WitrynaThe logistic equation assumes that the expected number of offspring decreases linearly with population size. The equation for the logistic growth follows as below: Here, … ceralan hoitava perusvoide
