The major evolutionary changes was overtime Pakicetus had an earbone with a feature unique to whales and an ankle bone that linked it to artiodactyls.
The answer is a) in biogeochemical cycles, nutrients are not synthesized anew but are recycled in the <span>biosphere.
Biogeochemical cycles are pathways by which chemical substances move through biosphere and geosphere (lithosphere), as well as atmosphere and hydrosphere. In these cycles nutrients are recycled, they are not lost. Let's take for example a carbon cycle:
</span>
<span>:- Carbon is released into the atmosphere as carbon dioxide from respiration.</span>
<span>- Producers (plants) absorb carbon dioxide and make carbohydrates in photosynthesis.</span>
<span>- Consumers (animals) eat producers and intake carbohydrates.</span>
<span>- After the death of both producers and consumers, decomposers (such as Actinobacteria, or other bacteria or fungi) eat that dead organisms and carbon are released into the environment.</span>
<span>
</span>
<span>So, carbon is not synthesized anew, but it is recycled.</span>
I think it should be A, not 100% sure tho
