Worked practice questions

Who published a descriptive theory of succession in 1916?

  1. Frederic Clements
  2. Arthur Tansley
  3. Robert Whittaker
  4. Eugene Odum
Show answer and solution

Correct answer: A. Frederic Clements

Clements put forward the descriptive, stage-wise theory of succession in 1916 and promoted it as a general ecological concept.

The stage where humus buildup alters the habitat so that one community replaces another is

  1. Reaction
  2. Nudation
  3. Ecesis
  4. Migration
Show answer and solution

Correct answer: A. Reaction

During reaction, organisms modify the habitat, for example by adding humus, which lets a new community take over.

The last stage of succession, when a stable climax community forms, is

  1. Nudation stage
  2. Stabilization
  3. Ecesis stage
  4. Migration stage
Show answer and solution

Correct answer: B. Stabilization

Stabilization marks the formation of the supposedly stable climax community at the end of the sequence.
