Answer:
Explanation:
Answer: the second one, aan article from www.europeanhistory.net that was updated in 2008.
i’d say an article in the Journal of European History
This source isn't very recent (but it doesnt need to be because Amaya is writing about the history of Europe), but we do know that it was updated, which implies that more relevent information was posted. The information is coming from a trustworthy source (we know this because of the url the article is from), so is likely very relevent and relaible. The last source is irrelevent becasue it's abput a carmaker who had/has nothing to do with the Columbian Exchange, and the first source is from a journal (we don't know who the journal belongs to, or what kind of information is in it).

While those representing the biological factors are the presence of prey and predators as well as other things. Most organisms or species adapt to strive which others might try to live up to their inbuilt habitat needs. A habitat does not necessarily refer to geographical area but can also be within the soil or inside of a branch or stem or other things which a living organism can live in. Homeostasis is essential in living organisms in a habitat because it helps to control and maintain them in optimum conditions which might have been necessary through adversary or habitat change.
