D: Where two continental plates are colliding, creating a convergent boundary. One plate slips under the other because of convection currents in the mantle.
I believe the correct answer is upwelling. Lets say we have producers such as plankton. well upwelling currents bring dead matter from the ocean floor up to the surface, creating plankton.
I believe it would be false. Termites are generally the first on human remains. I could be wrong though.
