Why are fossils<br> important in the<br> development of the<br> geologic time scale?
olga55 [171]
Fossils are fundamental to the geologic time scale. The names of most of the eons and eras end in zoic, because these time intervals are often recognized on the basis of animal life. Rocks formed during the Proterozoic Eon may have fossils of relative simple organisms, such as bacteria, algae, and wormlike animals

trapecia [35]

To know the answer, you either know what is really the nature and chemistry of a sugar solution. You can also know the answer by knowing the meaning of entropy.

Cellular respiration release co2 and photosynthesis absorbs co2. these two reactions are part of which biogeochemical cycle?
Naddika [18.5K]

The metabolic process that takes place in an organism's cells is called cellular respiration. Both photosynthesis and cellular respiration contribute carbon dioxide to the biogeochemical cycle.

<u>What is biogeochemical cycle?</u>

The mechanism that distributes and circulates abiotic chemical elements among the various realms of the planet is known as the biogeochemical cycle. The carbon, water, nitrogen, phosphorus cycle, etc. are all included.

Carbon dioxide is released during cellular respiration as a waste gas into the atmosphere, where it is then taken by plants to produce energy, which is then utilized by the organism, which then releases more carbon dioxide. The ecological chain's carbon cycle continues from the producer to the consumer.

Therefore, the carbon cycle is influenced by photosynthesis and cellular respiration.
