As new evidence and when new organisms are discovered You're welcome.
Biotic.
go to a new web
If you added one or more organisms to a food web, it would be unbalanced for a time and then a new equilibrium would be reached that might or might not include the organisms that were added.
I believe you are referring to evolution, which occurs as a result of natural selection causing species to change into new species over time.
You have to change the food gradually by mixing the original in with the new food. You then add more and more of the new food until it's all of the new food. By then your puppy's digestive system has adjusted to the new food. When you change foods all at once, it upsets the digestive system.
as new evidence and more kinds of organism are discovered
Moving to new areas.
Changes in the environment can cause some organisms to have to find a new way of living. Others might need to find a new source of food, or move to an area where they can live their lives as they were before. Changes in temperature is a major climate changer. It can make most animals migrate to a completely different area of the world, just by a little difference in the temperature. Changes in the environment can be devastating to some organisms and good to others. It can take away sources of food and water, or it can give new ones to the organisms that so desperately need them to survive.
The organisms get blocked off from other organisms so the original organisms change to get used to their new environment and then they mate with each other, speciation.***Im am trying to find the answer to this question but i hate this site becasue i can just change the answer, or anyone could.
