Mrs. roberts' class was designing science experiments. carl and his partner decided to use the outdoor classroom as their laboratory. since there was a bird feeder in the outdoor classroom, they decided to design an experiment about the feeding habits of birds in their area. which question would be most appropriate to guide the scientific investigation? a) what do birds eat? b) what type of seeds do birds prefer? c) which seeds do our feeder birds prefer? d) which types of seeds do our feeder birds eat?

D) Which types of seeds do our feeder birds eat?

Explanation:

A  feeder bird is an outdoor object intended to provide food for birds, usually has millet seeds, sunflower, saffron or colza. Because the feeder bird has many different seeds, birds may eat more seeds than one, so some people may be curious about which seeds birds eat the most and which ones eat the least. So, regarding the research Carl and his partner want to start, the most appropriate question to guide scientific research would be "Which types of seeds of our feeder birds eat?"
