A scientist wanted to determine if two newly discovered populations of insects exchanged information with other members of the same population about the location of a food source. The scientist set up a systematic observation in which food was placed for the insects to find. Over a period of time, the scientist recorded how many insects were found at the food source. The scientist collected the following data: A graph showing the number of insects recorded at a food source over a period of time. On the horizontal x-axis is time. On the vertical y-axis is the number of insects. Both populations start at 1 insect. At 2 minutes, both are at 2 insects. At three minutes, population 1 drops to 1 and population 2 increases to 4. At 4 minutes, population 1 increases to 4 and population 2 increases to 10. At 5 minutes population 1 increases to 5 and population 2 increases to 15. At 6 minutes, population 1 peaks at 6 and population 2 increases to 17. At 7 minutes, population 1 drops to 5 insects and population 2 rises to 18. At 8 minutes population 1 drops to 4 and population 2 increases to 19. © 2012 FLVS The scientist concludes that population 2 has a greater chance of survival than population 1. What is the correct response to the scientist's conclusion? (2 points)
Invalid because it can be deduced that population 2 will run out of food before population 1.
Invalid because survival is not dependent on the data found in the observation.
Valid because the data shows population 2 is able to communicate with one another.
Valid because the data reveals population 1 is found in lower numbers than population 2.
