Answer 1

ANS 17) Any relative discrete event intie that disrupts ecosystem community or population structure and changes resources substrate availibilty or the physical environment:

The correct answer is : a) Disturbance

---------------------------------------------------------------------------------------------------------------------------------------------------------

ANS 18) Developed the thraditional succession theory in which all species act together throughout the very predictable pattern of succession:

The correct answer is: b) Succession or Ecological Succession.

------------------------------------------------------------------------------------------------------------------------------------------------------

ANS 19) A community that occurs late in succession whose populations remain stable until disrupted by disturbance:

The correct answer is: e) Climax community

-----------------------------------------------------------------------------------------------------------------------------------------------------

ANS 20) Changes in vegetation communities that take place over time following a disturbance:

The correct answer is : c) Clements

-----------------------------------------------------------------------------------------------------------------------------------------------------

ANS 21) Developed the tolerance concept of succession in whoch random events (disturbances) influence colonization and create multiple pathways (or patterns) of succession:

The correct answer is: d) Gleason

---------------------------------------------------------------------------------------------------------------------------------------------------------

ANS 22) Disturbance can alter a community's stable environmental conditions.Another ecological term for a stable environment is:

The correct answer is option d) Equilibrium

---------------------------------------------------------------------------------------------------------------------------------------------------------

ANS 23) Joseph connell's intermediate disturbance hypthesis proposes that:

The correct answer is option a) species diversity is highest at intermediate frequencies of disturbance.

--------------------------------------------------------------------------------------------------------------------------------------------------------

ANS 24) Intermediate levels of disturbance often lead to higher diversity cause:

The correct answer is option d) Both species that do well at low disturbance and those that do well at high disturbance are usually present
