the arrow between the creosote bush and the grasshopper
the arrow between the kit fox and the coyote
the arrow between the rattlesnake and the red - tailed hawk
the arrow between the creosote bush and the desert iguana

Explanation:

• Producers (e.g., creosote bush) are at the base of the food web. Primary consumers (e.g., desert woodrat, grasshopper, desert iguana) eat producers. Secondary consumers eat primary consumers. Tertiary consumers eat secondary consumers.
• The arrow between the creosote bush and the desert woodrat: creosote bush (producer) → desert woodrat (primary consumer).
• The arrow between the creosote bush and the grasshopper: creosote bush (producer) → grasshopper (primary consumer).
• The arrow between the kit fox and the coyote: kit fox (secondary consumer) → coyote (tertiary consumer).
• The arrow between the rattlesnake and the red - tailed hawk: rattlesnake (secondary consumer) → red - tailed hawk (tertiary consumer).
• The arrow between the creosote bush and the desert iguana: creosote bush (producer) → desert iguana (primary consumer).

Answer:

the arrow between the kit fox and the coyote, the arrow between the rattlesnake and the red - tailed hawk
