Answer:
Positive feedback is used to build more contractions.
Explanation:
Positive feedback mechanism in humans is also observed during childbirth which is induced by the pressing of the ovarian wall by the baby.
The pressing sensation is passed to the brain via different nerves, and in response, the brain stimulates the pituitary to produce oxytocin.
Oxytocin is responsible for the contractions of the uterine muscles which cause the movement of the fetus towards the cervix, further increasing the stimulus.
The positive feedback loop continues until the baby is born.

Explanation:
Secondary consumers form the third trophic level in a food chain or food web. They eat primary consumers which in turn eat the producers. An organism can have a different consumer level according to its position in the given good chain.
In the given food web; rattle snake, kit fox, coyote and raven eat many things simultaneously. However all of them also eat desert woodrat. Desert woodrat is a primary consumer since it consumes producer plants like creosote bush and beavertail cactus. Rattle snake, kit fox, coyote and raven are secondary consumers since they eat the primary consumer (desert woodrat). Desert iguana is not a secondary consumer. It directly feeds on creosote bush so it is a primary consumer.
