Answer:
Explanation:
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Explanation:
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
For example:
When food is eaten it is digested by converting it into smaller particles. These smaller particles are than digest and gives the energy to our body. The energy which produced is just come from our food on this base we can say that mass neither created nor destroyed but it change one form to another, just like the form from food to energy.
Another example:
In given photosynthesis reaction:
6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂
there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.

The pattern of the flow of energy in the ecosystem take place in an unidirectional pattern. In the ecosystem, unidirectional pattern of energy flow should be present, following the law of thermodynamics which states that the amount of energy in the universe is constant. It cannot be created or destroyed, however, it may be changed into another form of energy. Example: chemical to heat. The law also says that without degradation into heat energy, non-random energies like mechanical, chemical or radiant energy cannot be changed.
