Answer:
False
Explanation:
Mass and volume are two different quantities. In fact:
- Mass is a scalar quantity representing the "amount of matter" contained in a certain substance. It is measured in kilograms (kg), which is one of the 7 fundamental SI units.
- Volume is a scalar quantity representing the amount of "three-dimensional space" occupied by an object or a substance. It is measured in cubic meters (
).
Therefore, mass and volume are two different quantities. They are related through another quantity called density, given by:

where
m is the mass
V is the volume
So the density of a substance represents the amount of mass contained in a certain volume of the substance.
Matter can be recycled, but energy cannot. Also, only 10% of the energy is passed through each trophic level.
They move through the ecosystem
Day is simply when a part of the world is getting direct sunlight and night is when the sun is not facing that part of the world and relies on the reflection of the sun on to the moon to get sunlight.
