Positive feedback loops are the opposite of negative feedback loops. In a positive feedback loop, any
change in the original variable triggers mechanisms that actually push the variable further in the direction

the element that provides strength to the exoskeletons of clams and oysters is phosphorus.

this is so because calcium carbonate is the main component in the shells. calcium carbonate is strengthened by phosphorus.
