Since the corals lack the zooxanthella that are found in tropical coral reefs because the zooxanthella require sunlight and there is no sunlight, the corals are built upwards instead of across. The polyps build the coral this way because they are filter feeders. The correct answer is C, filter feeders.
Roots are built to absorb more and are placed right in their environment that they will be absorbing nutrients. Unlike leaves and stems, roots are not exposed to the daily elements in the outdoors and therefore don’t need the protection and filter that the waxy cuticle provides.
I believe this is the difference..
I hope this helps! :)
