Food Chains
Brittlebush Wood rat Western Diamondback Red Tailed Hawk
Rattlesnake
Prickly pear cactus Antelope Squirrel Red Tailed Hawk
How Organisms Depend On Each Other
The food chain above shows that all organisms are interdependent on something in order to survive.
The wood rat and Antelope squirrel are both primary consumers, they rely on the nutrients from the
producer for their energy and survival. The Western diamondback rattlesnake is therefore the
secondary consumer, the snake is depending on the woodrat to have been provided its energy in order
for it to have survived, so it can prey on it so it can consume it for its own energy. The Red-tailed
hawk, however, is the Quaternary consumer of this food chain, it a predator that has a lot of prey,
however, is not often preyed on itself. Its relying on the producers, primary and secondary consumers
to have all done their part for the hawk to be able to gain its energy from the snake and antelope
squirrel.
