the chart below describes two different organisms living in the same ecosystem. based on the information in the chart, which of the following is most likely the correct explanation of the relationship of the two organisms? (2 points)
a graph of population over time. population is represented on the y axis. time is represented on the x axis. a blue line is drawn rising and falling up and down over time, representing the population of one organism. a red line, representing the population of the second organism, is drawn rising and falling up and down over time with roughly the same shape as the blue line, but shifted slightly to the left.
competitors for the same food
predator and prey
an invasive species and a native species
two types of prey hunted by the same predator

Answer: predator and prey

Explanation:

The described graph illustrates the cycle of a predator and prey population.  The population curves for predator and prey are not synchronized with each other and their amplitudes differ.

Changes in the prey population will not result in immediate or exactly identical changes in the predator population.

In the attached image, the red line represents the prey population and the blue the predator population. As it can be observed, when the prey population increases in size, the predator population size increases too.

However, this increase is not of the same size and is delayed in time. The predator population will continue to increase even though the prey population has started to decrease.

This has to do with the fact that the adult predators mated and gave birth when the food availability was still high. However, these new young individuals will not survive and reproduce due to decreasing prey. As the prey continues to decrease, more and more predators will perish.

The same cycle will then repeat over and over again.
