Co-evolution

Explanation:

A series of reciprocal adaptations in predator and prey populations describes co-dependence or co-evolution

In co-evolution, two species which are in association evolve together due to their relationship Both the species have different ancestryInteractions exhibited by co-evolution are: host parasite interaction, prey predator association, evolution of long proboscis in insects for taking nectar from flowers Predation is a very short term behavior in which two different species interact with each other for the demand of energy, one is prey and the other is predatorFor successful predation, predator wants minimum energy investment and maximum energy Increase in prey population in any given area attracts predator population, hence population of predator also increases in that areaIncrease in predator population results in decrease in prey population after some time decrease in prey population leads to decrease in predator population also

Due to the presence of larger vessels.

Explanation:

Due to the presence of larger vessels of hardwoods in the tree, water move faster in that tree as compared to other type of plants. in smaller plants, small vessels are present which able them to move less amount of water as compared to large trees which have large vessels. It tells us that the tree adopted the environmental changes so that's why to overcome the change, they use more water.
