What depth range does the thermocline span?

This is what i found on google “phytoplankton, tiny organisms that live in the ocean, are autotrophs. some types of bacteria are autotrophs. most autotrophs use a process called photosynthesis to make their food.” i hope this you for what your looking for

Organism, organ system, organs, tissue, cells

Mg is used to measure mass

It would be cell respiration
