Its because the ozone layers are weakening because of global warming
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.
Answer:
This fundamental structural unit consists of a silicon cation (black in photo) surrounded by four oxygen anions (red in photo), giving it four negative charges. It is found in all silicate minerals (ie. amphibole, olivine, pyroxene, quartz, feldspar, etc.). The silica tetrahedra may be arranged in chains (ex: pyroxenes), double chains (ex. amphiboles), sheets (ex: micas), and frameworks (ex: quartz, feldspars), forming the basic structure of the planet.
