Graduating from high school this year makes me feel a bit sad. Biology was such a fun but crazy class.
Enough of my sentiments; I'm here to help, :-).
This answer is dependent upon what ecosystem you choose your project over.
So, abiotic factors are nonliving things in an ecosystem. Biotic factors are living organisms and anything alive.
For instance, if you choose a pond for your ecosystem then the water, soil, maybe trash would be abiotic factors. Some could argue there is living material within the water and soil but those abiotic factors are not alive. I mean water is not alive but it could be a home to biotic factors like microorganisms such as protozoans and worms. The grass and trees and animals around a pond would be biotic factors.
Hope you get the idea. if there's any questions then leave a comment and I'll help. Good luck!
The precambrian era makes up about 90% of the earths history, but there was little to no living organisms at the time other than microscopic ones. The first eukaryotes were found in the cambrian period after the precambrian period, not only that but at the end of the precambrian era in the Proterozoic era there was a mass extinction of about 70-80% of all living organisms
This would actually be known to originate in the "nucleic acid". This would have nothing to do with the DNA it's self, and also protein has nothing to do with it also.<span>Nucleic Acid would be small particals in the cells that would consists of molecules would some sort of chain which would then lead to the DNA, but it would actually have not resemblance of the nucleic acid at any point.
