Answer:
I believe the correct answer is ALL choices. (like question 9 on this particular test that was graded correct and did not provide an "all of the above" choice either)
Step-by-step explanation:
Although the ody ssey unit does not precisely confirm each one of these choices specifically, it does state that filter feeding is done by most aquatic invertebrates like sponges and Baleen whales, then the unit material promptly moves on to data about herbivores and carnivores.
However, science info elsewhere lists ALL choices as filter feeders. Unfortunately for some reason I forgot to click dolphin as intended and after grading within ody ssey ware program I received an orange tic mark versus a red X(completely wrong), whoops. I am assuming because of not choosing as intended, dolphin as well. Heres the photo, otherwise I got all other questions correct and received a 98.5% on this assignment.
