Answer:
c) Tertiary consumers always have greater body mass than primary and secondary consumers in a given system
Explanation:
This statement has two flaws. One of them is that the tertiary consumers usually tend to have smaller body mass than the primary and secondary consumers, so it is a false statement. The other one is that it doesn't have any connection with the numbers of the tertiary consumers compared to the primary and secondary consumers. There are several reasons as to why the tertiary consumers tend to be much more rare than the primary and secondary consumers. The lesser amount of food energy available to them and the need of very large ranges to satisfy the food energy demand of their bodies being the two crucial ones. Through the trophic levels, the energy transferred fro one to another trophic level is around 10%, so the tertiary consumers get very little from the initial energy. Also, because they need much more food in order to satisfy their energy demands, they have to have large ranges, with abundance of prey animals, so that they can survive, which is another reason as to why they are much fewer in number than the primary and secondary consumers.

Explanation:
The ocean-floor feature that is associated with trenches is a subduction zone. An oceanic trench is characterized by a narrow and very deep depression on the sea floor. This depression is caused by a subduction zone wherein two plate boundaries converge and one sinks at the bottom of the other plate, forming a thin and deep region between the two plates.
