Chооse the best selectiоns to mаke the pаrаgraph below about competition accurate. Competition between two different species of organism is called [Ans1] competition. The impact competition has on the competing species is that it has a [ans2] fitness consequence on one species and a [ans3] fitness consequence on the second species. Given these fitness consequences, species that live together will often engage in [ans4]. Over evolutionary time,competing species that live together will begin to have traits that are more [ans5] than those same species living apart. This long-term change in traits is often called [ans6]
