Arrange the stages of ecological succession in the sequence in which they occur.
migration
reaction
nudation
ecesis
stabilization
competition

The stages of ecological succession is as follows:

nudation→migration→ecesis→competition→reaction→stabilization.

Explanation:

The complete process of succession involves certain steps namely-

         a) Migration, spreading of seed, spores etc.

          b) Ecesis ,Establishment of species.

          d) Aggregation.

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

the relative standard reduction potential of the half-cell in which reduction occurs; more positive than the other half-cell. reduction is a chemical process in which electrons are added to an atom or an ion; it always occurs accompanied by oxidation of the reducing agent.
