A water molecule changes form, from a solid, liquid and gas; the amount of water molecules on Earth has remained constant.  This is an example of what scientific concept?

• Law of  Conservation of Energy
• Law of Thermodynamics
• Law of Conservation of Matter
• Law of Conservation of Motion

In the food web above, what primary source do all the tertiary consumers pictured here receive the energy needed to sustain themselves?

Matter can recycle through the biosphere  because

• matter does not change into new compounds
• matter is assembled into chemical compounds
• biological systems do not use up matter, they simply transform it
• biological systems use only carbon, oxygen, hydrogen and nitrogen
