Introduction: A constant change during species composition in a community is called succession. Primary and secondary ways of succession share a common set of processes. Primary succession, which started with the soil loss after the volcano, determines the initial period of ecological succession.
Answer to Problem 1MC
Correct answer: Option a. “primary succession”.
Explanation of Solution
Reasons for the correct statement:
A change that occurs in an area where no previous community existed is termed as primary succession. A tangled combination of life did not start from bare rocks or naked soil, rather it develops into stage after long time, this stage is termed as succession.
Hence, option a. is correct.
Reasons for the incorrect statements:
Option b. is given as “secondary succession”.
A change that takes place in an area, which is pre-existing or distributed somewhere but its extinction has not occurred is called secondary succession. Hence, option b. is an incorrect answer.
Option c. is given as “interspecific succession”.
This type of competition arises between different species occupying the same ecological area. Hence, option c. is an incorrect answer.
Option d. is given as “niche succession”.
The response of an organism or a population to the distribution of
Hence, options b., c., and d. are incorrect answers.
The orderly progress of communities, starting from bare rock with no soil or traces of a previous community, is called primary succession.
