2. List four steps of a potential food chain that could be found in the intertidal zone and label the producer, the herbivore, and the carnivores.
A mussel may filter many gallons of water each day through its body. What does this do to the levels of contamination that might be found in their tissues?
Bacteria are often overlooked by students when they consider food webs. Why is their role important?
Bacteria will act as decomposers and break down dead organisms chemically. Why is this important?
