Answer:
Answer is A, interspecific competition.
Step-by-step explanation:
Interspecific competition is considered as a type of competition whereby members of different species compete for the available shared resource.
In this case, the patch of weeds growing on soil at that period comprises of members of different species, and they are all competing the available shared resource.
The types of interspecific competition include
* Predation.... a situation whereby one organism kills the other for food. e.g Lion and antelope.
* parasitism... situation where one organism depends on another for survival,and in the process, causing damages to the host organism. e.g Dog and tick.
* commensalism....one organism depends on another only for food and protection without causing harm to the other organism. e.g shark and remora fish.
* mutualism...both organisms contribute and benefit from the relationship. Alga and fungi in lichen.
