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.
This statement about matter is true: MATTER IS MADE UP OF ATOMS AND HAS MASS.
Matter is defined as anything that has mass and occupies space. The mass of an object is the measure of the extent to which the object can resist a change in its direction when a force is applied to it. A matter is usually made up of atoms, which is defined as the smallest component of any matter. Therefore matter is made up of atoms and it has mass.
