Question

Gradual changes of species structure inhabiting a geographical area

A)Secondary succession
B)Primary succession
C)both aquatic and primary succession
D)Both secondary and primary succession

Answer 1

Gradual changes of species structure inhabiting a geographical area are associated with (D) both secondary and primary succession.

Primary succession occurs in an area where no soil exists, such as on a newly formed volcanic island, while secondary succession occurs in an area where soil is present but has been disturbed, such as after a wildfire or deforestation. In both cases, gradual changes in species structure occur over time.
