What kind of symbiosis exist between grass and migrating animals?

Answer 1

Grazing increases root production. This could only be described as symbiosis in a very loose sense. Generally symbiotic relationships are much more dependant ...such as the termite and its gut bacteria or to a lesser degree the mutualism of an anenome and a clown fish.

Answer 2

Grass and migrating animals have a mutualistic symbiotic relationship. The animals graze on the grass, which helps control the grass height and density, promoting new growth. In return, the animals receive a food source while also dispersing seeds through their droppings, aiding in the grass's reproduction.
