Explanation:
Primary succession starts off with the modification of a previously unoccupied area along with increasing variation- this occurs in barren areas devoid of life like sand dunes, and lava flows. Communities in a primary succession include:
-barren rock
-bacteria and fungi
-mosses and lichen
Further Explanation:
Succession involves small scale changes within a community that occur repeatedly over the life of that community.
Ecological communities are highly dynamic- they gradually evolve. Typically their progression involves:
- colonizing species exploiting uninhabited areas (Primary succession)
- becoming a habitable and increasingly complex community
- there is increased diversity of organisms (Secondary)
The makeup of biological communities is crucial to defining Primary and Secondary succession; eventually, through changes in this makeup, a steady-state or equilibrium is reached called a climax community. While Primary succession starts off with the modification of a previously unoccupied area along with increasing variation; secondary succession begins after major disruption in the community such as fires, storms and flooding.
However, the process of becoming a climax community can be pretty complicated- it is very dependent on other factors like temperature and rainfall. Communities that experience rapid change, frequent major disruptions and even human intervention, are less likely to attain a stable equilibrium and may never become climax communities.

El sistema de nomenclatura binominal identifica a una especie inequívocamente, pues no puede haber dos especies diferentes con el mismo nombre y evita la pluralidad de nombres comunes con el que se la pueda conocer según el idioma o región, que además pueden nombrar a más de un taxón diferente.
Due to human activities, the greenhouse gases are the most substantial mediator of the witnessed climate change since the mid-20th century. Globally, the overall emissions of greenhouse gases due to human activities have upsurged by 35 % from 1990 to 2010.
The concentrations of carbon dioxide and other greenhouse gases in the atmosphere have upsurged since the start of the industrial revolution. Of the greenhouse gases, the fluorinated gases exhibit an average lifetime in the atmosphere of a few weeks to thousands of years.
The fluorinated gases refer to an array of gases, which comprise fluorine, incorporating perfluorocarbons, hydrofluorocarbons, and sulfur hexafluoride, among other chemicals.
These gases are discharged due to numerous industrial procedures and household and commercial applications and do not take place naturally. It is at certain instances used as the substitutes for the ozone-depleting components like CFCs.
Answer: in biology an interacting group of various species in a common location is called. COMMUNITY
