1st level consumers are usualy herbnivorous insects(cricket), reptiles(Sonoran desert tortoise), birds(Costa's hummingbird)and mammals( desert cottontail).
2nd level consumers are carnivorous reptiles(gila monster), arachnids(scorpion), insects(tarantula hawk wasp), mammals(coyote), and birds(red-tail hawk).
3rd level consumers are creatures that have no compunction about eating other canivores, suchas coyotes, hawks, and mountain lions.

waypoint abiotic factors
The desert is a dry, harsh landscape. This is caused by mountains and ridges that hinder clouds being able to enter the desert sky. The lack of clouds allows the desert to feel the full heat of the sun during daylight hours and not retain it during the night(ranging from an average of 100°F in the day time in the Sahara to an average of -2°F during a gobi night). This also means the desert expiriences very little rain fall,1in. yearly on average, sometimes going years without it. Deserts also tend to have large amounts of wind caused by high presure zones on or near the mountains. The soil in deserts is usually poor because it's sand, dry and loose.

way point animals
The desert is home to many different animals including mamals, snakes, insects, and arachnids. Camels are capable of storing fat in their humps and can go without water for up to 2 weeks. Sidewinder rattlesnakes developed a unique way to travel across the sand where snakes usually have trouble getting traction, and insects and arachnids have hard outer shells to keep them hydrated.
Common desetr animals are sidewinder rattlesnakes(Crotalus cerastes cerastes), bacturian camels(Camelus bactrianus), emporer scorpions(Pandinius imperator), centipede(Chilopoda), and coyotes(Canis latrans).
