As a tool for objectively studying populations, population ecologists rely on a series of statistical measures, known as demographic parameters, to describe that population (Lebreton et al. 1992).

- Biotic Potential:
- Life tables:
What is population and types?
A discrete assemblage of entities with identifiable characteristics such as people , animals with the objective of analysis and data collection is called a population. It consists of a similar group of species who dwell in a particular geographical location with the capacity to interbreed.
What are the five characteristics of populations Ecologists study?
What characteristics do ecologists study to learn about populations? Ecologists study populations by examining their geographic range, growth rate, density and distribution, and age structure!
What are the three types of population?
Individuals of a population can be distributed in one of three basic patterns: uniform, random, or clumped .
What makes up an ecosystem?
An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape , work together to form a bubble of life.
