Answer:
Animals burrow tunnels into the ground
Step-by-step explanation:
The geosphere is composed of all the crust on the plant. As all other spheres do, the geosphere too is in constant interaction with the other spheres. In this case we have animals that burrow tunnels into the ground. The ground is part of the geosphere, while the animals are part of the biosphere, which is the sphere that is composed of all living organisms. Since the animals are doing an activity that changes the ground, we have a situation in which the biosphere interacts with the geosphere.
