Document Summary

Intrinsic factors : specific to the characteristics of a particular species or population. Given abundant resources, most populations show spectacular growth. A population will grow smoothly until further growth becomes limited by environmental. When a population is small in comparison to its resources, every individual has plenty to. Biotic potential : growth of a population in optimal environmental conditions and in the. As the numbers increase, more individuals are available to reproduce, but overcrowding. Population density (number of individuals per unit area) increases and the environment. Positive feedback : increase in output leads to a further increase in output. A system that is self-regulating is said to have the property of homeostasis, which. Dynamic equilibrium: the system constantly responds to small changes and disturbances implies a state of equilibrium so that it returns to a state of equilibrium. Ex. if our bodies heat up, sweat is produced and cools us. Some variations in environments and populations appear to be self-regulating.
