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? (4 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.

a
Competitors for the same food

b
Predator and prey

c
An invasive species and a native species

d
Two types of prey hunted by the same predator

You will be galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. before you conduct your experiment, you need to form a hypothesis. a hypothesis is a prediction of what you think will happen in the experiment. the hypothesis is a statement that describes “if” a certain set of circumstances are present “then” there will be a specific result that will occur.record your hypothesis here: record the results from step one of the experiment (dropping the objects in the air): first trial: second trial: third trial: record the results from step two of the experiment (dropping the objects in a vacuum): first trial: second trial: third trial: did the experiment support your hypothesis? using the data from your experiment, describe why you believe your hypothesis was either proven or disproven.what forces were acting on the objects dropped in the air? what force was acting on the objects dropped in the vacuum? part two: comparing forceschoose two forces and compare and contrast these forces. you must provide two ways that they are alike and two ways that they are different. you may make a list, write in paragraph form, or make a chart.choose two forces and compare and contrast these forces. these must be different forces than used in the prior question. provide two ways that they are similar and two ways that they are different. you may make a list, write it out, or make a chart.

This is the process of making a prediction based on the results of prior observations of similar events.
