Answer: The mass of carbon in the products is greater than the mass of carbon in the reactants.
Explanation:
<h2><u>Answer:</u></h2>
Fossil: is preserved pre historic life form present under ground at high pressure for a long time.Animal die and burried under layers of sediments.
It provides evidence about the history of life on earth. It also shows different groups of organisms, including species,that have changed over time. Because the formation of any fossil depends upon the precise combination of conditions.
As the world changes, plants and animals change with time . From fossils we compare organisms of modern time with ancient , the species we see today are very different from species that lived in the past. Thus, the fossil record can be used to show that organisms changed to meet new condition.
Answer:
Food waste
Explanation:
Food waste is an organic compound, unlike the other choices. Organic compounds are biodegradable because living organisms, such as decomposers, have evolved mechanisms of breaking down these large carbon-based compounds/polymers into smaller molecules for energy. Food waste is therefore easily recycled into the environment.
The others do not have naturally occurring organisms to break them down or reduce them. They would, therefore, accumulate in the environment. This is exactly what is happening to plastc pollution. Accumulation of plastic in the environment is due to fact that they are not broken down into simpler molecules by any naturally occurring bacteria or organisms in the environment.
