Answer:
The plant's tubelike structure to carry water is called stomata.
There are four spheres on the Earth, lithosphere, biosphere, atmosphere, hydrosphere, and the prairie dog interacts with all of them.
Lithosphere; the prairie dog uses the lithosphere for living and hiding (inside the ground) and for searching food and mates on the surface of the land.
Biosphere; in here we can include the interactions the prairie dog has with the members of its own species, but also with the living organisms it uses as a food, and the living organisms that are a threat to it and it avoids them.
Atmosphere; it uses the atmosphere in the way that it uses the oxygen for breathing and thus living.
Hydrosphere; the prairie dog is not a big fan of the the water surfaces, but still it uses small amounts of water for drinking so that it can survive.
Not really sure just need seem points aha
