what would be the difference between a new species and an old species?

"Why new species can not replace the original species. If they both do the same thing what would be the difference between a new species and an old species?"

- This question might be confusing and misleading in my opinon. If you're talking about two different species, they're clrearly not the same thing because they're different.

- Also, there is no such thing as new and old species. They're either extinct or not. But "old" isn't the correct termiinology.

So, if we focus in the second observation that was done above, all we can say it's that it is part of the cycle of nature. Some species go extinct to give rise to new ones (note: only if this occurs naturally). Depending on how you look at it, you can also call it evolution.

good thing- during decomposition the organic molecules in organic matter are broken down into simpler organic molecules that require further decomposition or into mineralised nutrients

bad thing- it can be harmful in crop productivity

this transfer is call conjunction
