The correct Answer is:
To determine the correct answer to the question regarding primary succession, let's analyze each option step by step. ### Step-by-Step Solution: 1. **Understand Primary Succession**: - Primary succession refers to the development of biotic communities in an area that was previously uninhabited or devoid of soil and life. This typically occurs on bare substrates such as rocks or after volcanic eruptions. 2. **Evaluate Each Option**: - **(a) Newly exposed habitat**: This is the correct choice. Primary succession occurs in newly exposed habitats where no previous biological community existed. Examples include areas exposed by glacial retreat or volcanic eruptions. - **(b) Cleared forest area**: This option refers to an area where a biological community previously existed but was cleared. This scenario is classified as secondary succession, not primary succession. - **(c) Freshly harvested crop field**: Similar to the cleared forest area, a harvested crop field has previously supported a biological community. Thus, it is also an example of secondary succession. - **(d) Pond filled after a dry season**: This situation involves a temporary habitat that has undergone changes but was previously inhabited. This is another example of secondary succession. 3. **Conclusion**: - After evaluating all the options, the only scenario that fits the definition of primary succession is **(a) Newly exposed habitat**. ### Final Answer: **(a) Newly exposed habitat** ---

There were lot of organisms A in the crop fields in an area. These organisms used to feed on organisms B also present in the crop fields but which damaged the standing crops. One day some people arrived in the fields and killed all the organisms A so that they could remove their C for making fancy items which were in great demand. Due to large scale killing of A, the population of B increased too much damaging all the crops in the area and causing a famine-like situation. Apart from A, there is another organism D which can also kill and eat B. Name A, B C and D.
