Answer 1

37.True

According to definition disturbance is any discrete event that disrupts ecosystem, community, and population structure. This is so as there will be a change in the resource pool, availability of substrate

38.False

At high levels of disturbance, more r-selected species will survive (as they are good dispersers) and K-selected species will survive at low levels of disturbance since they are better at the competition

39.Barnacles hitching a ride on the skin of a whale.

Commensalism one species get benefit while the other is neither benefitted or harmed. In barnacles and whale relationship, the barnacle gets the benefit, it gets an opportunity to feed by attaching itself on the back of the whale. Acacia and ant relationship is an example of mutualism in which both are benefitted and so is the relationship between dinoflagellates and termites. Tapeworm in the intestine exhibits parasitic relationships. While in mosquito and oxen relationship the only mosquito is benefitted.
