Answer:
D. Animals burrow tunnels into the ground
Explanation:
In this scenario we have interaction between the biosphere and the geosphere. The biosphere is represented by all of the living organisms on the planet Earth. The geosphere is represented by all of the crust on the planet Earth. The animals are living organisms, thus they are part of the biosphere, and by doing an activity in the ground, in this case burrowing tunnels, they interact with the geosphere, so we have an interaction between the biosphere and the geosphere.
