Density can be useful in identifying substances. It is also a convenient property because it provides a link (or conversion factor) between the mass and the volume of a substance. Mass and volume are extensive (or extrinsic) properties of matter - they depend on amount.
Answer:
Microbial mats.
Explanation:
Microbes formed sheets that were able to capture layers of sediment is called microbial mats. These mats of microbes provide good fossil evidence to the researchers. These microbial mats consist of bacteria and archaea which is considered the earliest form of life on earth. These microbial mats grow on moist places as compared to dry environment. About 3,500 million years ago, these microbes are the most important members of earth and maintainers of the ecosystems.

Answer:
C. They pollinate the flowers that only open at night.
Explanation:
A niche is the functional role an organism performs in the ecosystem. Simply, the question is asking for the role of nocturnal animals as pollinators.
- A pollinator is any organism the helps plants to transfer pollen grain from the anther of one flower to the stigma of another.
- This way, fertilization and crossing of genetic materials is achieved.
Nocturnal animals are animals that are very active at night. This is an evolutionary advantage for them because there is less danger at this point of the day.
Therefore, some nocturnal animals can help to pollinate flowers that only open at night.
