Under which environmental condition would primary succession occur ​
astraxan [27]

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.

How does music affect plant growth? To answer this question, Dr. Anderson set up an experimental chamber and exposed a group of
Ivanshal [37]

Answer:

The use of music

Explanation:

<em>The independent variable in the example is the use of music.</em>

The independent variable in research or experiment is a variable whose value is not affected by any other variable. That is, the value of an independent variable is not influenced by any other variable.

<u>In this case, the use of music stands alone and is not influenced by any other variable in the experiment. In actual fact, the use of music's effect is being tested in the experiment and hence, is not in itself influenced by any other variable.</u>
