Population Size Varies Because Of:

Abiotic Factors

·         Population size is the total number of organism of one species in a habitat

·         Population size of any species varies due to abiotic factors (light water space temperate chemical composition)

·         When abiotic factors are ideal, organisms grow fast and reproduce successfully (when temperature is ideal  for metabolic reactions they don't have to use up as  much energy maintaining body temperature, so energy can be used for growth/reproduction, population size increases)

·         When abiotic factors aren't ideal, organisms can't grow as fast or reproduce as successfully (when temperature is a lot higher/lower than optimum body temperature, energy has to be used to maintain
