.The Hippopotamus feeds chiefly to aquatic plants,but also looks for food on land.

Answer 2

The hippopotamus feeds chiefly on aquatic plants, but also looks for food on land.

Explanation:

• Here, on is used to describe the dependence of hippopotamus on aquatic plants and food on land.
• We can also use the word "at" in the first blank and make it, the "hippopotamus feeds chiefly at aquatic plants."
