Describe the patterns of survivorship and populations dispersion.
Answers
1 population is defined as all organisms in a particular geographic area that belong to the same species. When biologists study populations, they usually measure them in terms of population density, or the number of organisms per unit of volume or area. In some cases, the population density can be determined by simply counting the number of organisms in an area and dividing by the area. But many populations are too large, or the individuals are too hard to see or locate to directly count. In these cases, biologists must estimate the actual population density using a variety of methods.
2 One of the biggest factors that affect populations is life history, or the sequence of events in an organism's life that relate to its survival and reproduction. An organism's life history includes factors such as number of offspring produced, frequency of reproduction, amount of care and resources dedicated to offspring and what kind of survivorship curve
