Answer:
The age of fossils are in millions.
Explanation:
These fossils were present on the earth millions of years ago due to different and unique structure of the fossil. The fossil is present in the bottom of the middle layer indicates that the more age of fossil i.e. millions of years according to the law of superposition. This law states that in an undisturbed layers of rocks, the top layer is the younger layer than middle and bottom layers which is older than the top layer, so we can say that fossils from deeper layers are older than fossils from the top layers of rocks.
Answer:
This is possibly a bad idea because it could mess up the balance of the oceanic ecosystem and because of the drop in starfish, the whole food chain could get affected and plants and animals could die.

Together, all these organisms (bacteria, grass, shrubs, trees, insects, birds, and small mammals) make up a community.
Similar to human communities, where various types and races of people live and work together, this also happens in the animal kingdom. All of these different organisms live together in the same place and make up a community of their own.
The molecule formed by the connection of an amino group to the carboxyl group is referred to as carbamic acid.
This molecule, aside from the name mentioned is also often known as aminoformic acid or aminocarboxylic acid. This acid is formed in<u> low-temperature reactions</u>. When ammonia and carbon dioxide come into contact with one another at low enough temperatures, this acid is formed, but is very unstable and <u>will often quickly decompose</u>.

While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration. Without any oxygen, much less ATP would be produced.
