The correct option is B 2
Predation is a type of interaction where organisms belonging to one species (the predator) kill and eat organisms belonging to another species (prey). Example - Pisaster, a starfish feeding on marine invertebrates (small crabs, corals, sea anemones, barnacles, etc).
Parasitism is a type of population interaction between two living species in which one organism (the parasite) lives and derives nutrition from another specific organism (the host). It is of the following types:
1. Ectoparasitism - The word ecto means outer. The parasites live on the external surface of the host organism. Example - Ticks on dogs, lice in human hair, Cuscuta growing on green plants, etc.
2. Endoparasitism - The word endo means inner. The parasites live inside the body of host organism.
Example - Liver flukes that parasitise the liver in human beings.
Amensalism is a type of population interaction where one species is harmed and the other is unaffected (-/0 interaction). Example - Antibiotics (like Penicillin) produced by the fungi Penicillium notatum act against bacteria but have no negative or positive effect on the fungi.
Commensalism is a type of population interaction in which one species is benefited while the other is neither harmed nor benefited (+/0 interaction). Example - Orchids growing on a mango tree, barnacles growing on the back of a whale, etc.
