Squirrels are much like humans, they need to eat, breathe, and drink. They eat nuts, fruits, vegetables, and anything else they can find on the ground. They drink water from ponds, lakes, rivers and from some of the food they eat. Squirrels interact with the four spheres in diverse ways. They interact with the atmosphere by breathing. They interact with the hydrosphere by drinking fluids from the sources of food they can find and bodies of water. They use the geosphere by cracking the nuts they find on the ground; in some way they are much like raccoons, although raccoons wash their food before they eat it. They use the biosphere for the food that they eat. 

Fruit gives vitamins. The vegetables give other vitamins. And the plants do both. 

Squirrels eat the producers much like most consumers in the world besides bro the anteater. Which only eats decomposers.  

Decomposers are insects, well most of them are. Some of the decomposers are called fungi, they are mushrooms and muses. 

The producers store energy through photosynthesis. Photosynthesis is when a cell takes the energy from the heat and stores the energy.
