Document Summary
A coconut palm take 10 years to mature but live 60-70 years and produce offspring each year. Coconut palms invest resources in making stout stems that allow them to grow tall, extensive root system, large fruits (coconuts), molecules that make herbivores sick, enzymes that reduce infections from disease causing fungi. Births and immigration add individuals to the population. Deaths and emigration remove individuals in population. Population"s overall growth rate is function of birth rates, death rates, immigration rates and emigration rates. A population"s growth rate is change in number of individuals in populations ( n) per unit time ( t) If no immigration or emigration is occurring, then a population"s growth rate is equal to number of individuals (n) in population times the difference between the birth rate per individual (b) and death rate per individual (d) The difference between the birth rate and death rate per individual is called per capita rate of increase ( r)
