Answer 2

Explanation:

Commensalism :

• Commensalism is a relationship in which one organism, called the commensal, benefits from the other.
• The other organism, called the host, is, neither benefited nor harmed by this relationship.
• For example, remoras are marine fish that attach themselves to large marine animals such as sharks, whales, rays and turtles.
• Remoras are commensals and feed on the leftovers of the meals of the hosts, and also on the faecal matter of the hosts.
• The hosts also provide transport and protection to the remoras.
• Apparently, the hosts do not gain anything from this relationship.
• Similarly,epiphytes are commensals that grow on tree trunks for support and access to sunlight, and do not depend on the host tree for nutrition.
• The epiphyte absorbs moisture from the air or from the rainwater trickling down the tree trunk, and obtains nutrients from the decaying leaves that accumulate on the trunk.
• The host tree is unaffected by the epiphytes growing on it.
