Explaining Survival Differences Practice Test

Yuki observed a freshwater pond with many insects, algae, and water plants. She counted fish increasing from 60 to 90 and saw them eating insects near plants. She saw turtles sunning on logs and later found 2 new turtle nests. A land rabbit tried to swim, its fur got heavy and wet, and it quickly returned to dry land. Based on the evidence, what explains the survival differences?

Sofia studied a freshwater pond with moderate temperatures, lots of water plants and algae, many insects, and a shallow muddy bottom. She counted 120 fish and saw many baby fish swimming near plants. She also saw 7 turtles sunning on logs and later found 3 turtle nests with eggs. A land rabbit placed near the pond tried to enter the water, struggled to swim, and ran back to dry grass. According to the observations, why does the rabbit struggle in this habitat?
