Question

The blackberry's seeds must be digested by a bird before they can sprout. What type of relationship do the blackberry plants and the birds have? A. commensalism B. mutualism C. neutralism D. parasitism

I couldn't quite decide what "subject" this would be, so I chose Biology.

Answer 1

B. Mutualism
Because the bird has food from the blackberries but the blackberry seeds are distributed when the bird disposes of the seeds and other blackberry plants grow in different areas
