Solution

The correct option is B False
  • Interspecific interactions arise from the interaction of populations of two different species. There is no natural habitat on the earth that is inhabited by single species alone. For any species, the minimal requirement is one more species on which it can feed. Even a plant species, which makes its own food, can't survive alone, it needs soil microbes to break down the organic matter and return the inorganic nutrients for its use.
  • Amensalism is an interaction between two living individuals of different species in which an organism doesn't allow other organism to grow or live near it. For example, Penicillium doesn't allow the growth of Staphylococcus bacterium.
  • Commensalism is the relationship between two living individuals of different species in which one is benefitted while the other is neither harmed nor benefitted except to a negligible extent. For example, Sucker fish attaches itself to the under surface of shark with the help of its dorsal fin which is modified into holdfast. It is widely dispersed and remains protected from its predators.
  • In Commensalism, one species get benefitted and the other is neither harmed nor benefitted. In Amensalism, one species get harmed and the other is neither harmed nor benefitted.
So the given statement is false.
