INTERPRETING+THE+GRAPH

A) THE POPULATION OF THE TWO SPECIES FLUCTUATE FROM MAXIMUMS TO MINIMUMS OVER TIME AND NEITHER THE TWO MINIMUMS NOR THE TWO MAXIMUMS EVER COINCIDE AS THEY OCCUR CONSECUTIVELY. wE CAN SEE AN EXAMPLE OF A PREDATORY INTERACTION.

B) THE DOTTED LINE IS THE PREDATOR AND THE CONTINUOUS LINE IS THE PREY. bECAUSE A POPULATION OF PREDATORS THAT WAS GREATER THAN THE PREY WOULD BE UNSUSTAINABLE.

C) THE POISONING OF THE WATER WHICH AFFECTS BOTH SPECIES COULD EXPLAIN WHAT HAPPENS IN THE GRAPH.

C) AGAIN THIS IS LIKE THE CASE OF THE LYNX AND THE RABBIT, BUT WITH THREE POPULATIONS, ONE WHICH FEEDS OFF THE OTHER TWO.
