Which of these statements is a scientific question that might be asked about this food chain?
A. How would the populations of the fish change if shrimp started
eating fish?
B. Do mackerel eat more tuna or more shrimp in one day?
C. Where in the ocean do shrimp find the plankton that they eat?
D. How would a change in the population of shrimp affect the
populations of mackerel and tuna?

A

Explanation:

A, because there's a food chain that's going to Plankton to shrimp and so on. That would be a scientific question they might ask about. It's also related to what the question is asking about and it's a more simple answer. I wouldn't think B or C is what they would ask about because it's not really related to the food chain. For D, it's a really good question. But, the food chain only shows a Plankton going to shrimp and so on. D is a bit more into deep thought and it doesn't really relate to the picture either.
