Question

Study Island

A marine biology team is studying a marine ecosystem near a shallow coral reef. For their study, they install ten stations, each supplied with a thermometer and a video camera. The thermometers measure the water temperature, and the video cameras monitor the activity of the fish in each location.

The team takes turns watching the video and determines the average activity of the different fish species at different water temperatures over many months.

After the study, the team reports the average activity and not the actual number of active fish because

A. they ran out of time to watch all the video.
B. they were too lazy to count all the fish.
C. average measurements simplify a complex system.
D. the average of a system is more complicated to measure.

Answer 1

D: Average measurements simplify a complex system

Step-by-step explanation:

"A marine ecosystem is too complex for anyone to accurately measure the exact number of active fish. Instead, a limited number of measurements is used to find a reliable average.

Averages help to simplify a complex system and make it more understandable. When a system is very complex, people depend on summaries, averages, and examples to improve their understanding of the system."
