Answer:
B) Competition
Explanation:
According to the statement, the farmer has planted two species that requires same nutrients for their survival, thus, they are competing with each other for nutrients acquisition only.
Mutualism is not possible because, in this interaction, both species provides nutrients or other services that are beneficial for each partner. Here, both species don't compete at all rather they complement each other for better survival and growth in nature.
Likewise, in commensalism, one species provides benefits whereas other species doesn't provide any benefits neither cause harm to the first species. In the given question, no beneficial partner is involved, and also there is no neutral interaction exists (both are competing).
Lastly, parasitism is neither possible here because it is an interaction where any of the species starts eating the other species directly for its growth and development. In this category, the fittest will survive and other species will die. In this situation, it might be possible that one species is more aggressive and could behave opportunistically but, still, it is not directly eating the other species (feeding biomass) for its own survival.
Competition takes place when two or more organisms or species within an ecosystem seek the same resource. Since the two species of grass have similar nutrient needs, they will be competing with one another for the nutrients available in the soil of the plot of land.
Whichever species is better adapted to take in nutrients under the specific conditions present on this plot will most likely outcompete the other species and eventually take over the area.
