The following organisms are found in a grassland: mouse, mushroom, snake, clover,
prairie dog, grasshopper, hawk, dandelion, and grass.

In this relationship the clover, dandelion, and grass are all consumed by the grasshopper
who is eaten by the prairie dog or mouse. The mouse eats both the grasshoppers and grass
and is eaten by the snake and hawk. The prairie dog eats grass, and grasshoppers and is
eaten by the snake and hawk. The hawk eats the mouse, prairie dog and snake. The snake
eats the prairie dog, and mouse and is eaten by the hawk. The mushroom is a decomposer
and will not be eaten as an energy source.
