I think the answer is c) the preservatives slow the growth og mold and bacteria
A) This is predator-prey relationship.
B) Species A is prey and species B is predator.
- If prey population decreases in number, the predator population will also decrease because there is not enough food for predators to survive and vice versa.
- If predator population decreases, the prey population will increase because less prey will be eaten by predators and vice versa.
C) Let population A be Zebras, and population B Lions.
From the graph, at the beginning the there is increase in Lions, as well as in smaller rate in Zebras. At one point, the population of Lions begins to decrease, so they will eat less Zebras. This will allow Zebras to increase population. With more Zebras on the menu, more Lions will eat and increase their chance to survive. This leads to decrease in Zebra population. But again, with less Zebras, the Lion population must decrease allowing Zebra population to increase, and so on.

Only specific antibodies are produced following antigen presenting cells that bind to antigens. They capture and display the antigens to the antibodies.
