specifically‚ in ecology‚ as the predictable pattern of change in the species structure of an ecological community over time. There are two types of succession; primary and secondary. Primary succession refers to the successional development of plant communities that takes place on a site formerly devoid of vegetation and usually lack well developed soil.

between organisms and the environment; the connectedness between living systems and non-living systems on the Earth is called ecology. The term “ecology” which was coined by Ernst Haeckel comes from the Greek root words oikos logos literally meaning “the study of household”. Haeckel was referring to the interactions within the house of nature and we have used the word ecology (translated from the German Oekologie or Ökologie) to describe complex systems of life both extant and extinct. These interactions

Statistic and dynamic characteristics of population. 2. Growth curves patterns: J-shaped curve and S-shaped curve 3. Population regulation: Density-dependent and density-independent factors. 4. Human population patterns: - Population numbers. - Demographic transition and structure - Population urbanization
