Detailed explanation-1: -A predator and its prey generate a negative 2-link feedback by their interaction, through the negative effect of the predator on the prey and the positive effect of that prey on its predator.

Detailed explanation-2: -This cycle of predator and prey population variation repeats over time. Increase in predators leads to decrease in prey. Decrease in predators leads to increase in prey. This is a classic example of “balancing” or “negative” feedback.

Detailed explanation-3: -A good example of a negative feedback mechanism will be if the increase in temperature increases the amount of cloud cover. The increased cloud thickness or amount could reduce incoming solar radiation and limit warming.

Detailed explanation-4: -Perhaps the classical example of species interaction is predation: the symbiotic relationship in which one species survives on consuming the other species. The species that consume or win is the predator and the species that is eaten is the prey.

Detailed explanation-5: -Unlike producers, such as plants and seaweed, consumers need to eat other organisms to survive. This dependence between consumers and their food is shown in food chains and food webs. In this type of relationship, one organism hunts and eats another organism.
