What adaptation would be most useful to an insect that lives in the grass?

Animals in the grassland need water and sun to help the plants to grow.Then the bigger animals need the smaller animals so they can live. They also need sun and water like the the smaller animals.Then the bigger animals come to eat big animals.The very big animals want the small amimals to grow so they can have more food.All animalls need food,water,and sun.Even us people!
well, there are many animals in the savannah grassland. There are golden retrievers, elephants, and sea turtles. some plants are the jelly bean tree and the donut seeds.
