Question

1. a partial desert food web is shown.

which statement describes a relationship shown in the food web?
a gazelle consume coyotes and are predators to owls.
b rattlesnakes are predators to both mice and gazelle.
c brittlebush obtains all of its energy from jack rabbits and mice.
d scorpions consume crickets and are prey to rattlesnakes.

Explanation:

• Option A: Gazzelle are herbivores (eat plants like Prickly Pear Cactus, Sand Grass), and Coyotes eat Gazzelle, but Gazzelle don't consume Coyotes. Also, Gazzelle and Owls don't have a predator - prey relationship as Owls eat small animals like mice, not Gazzelle. So A is incorrect.
• Option B: Rattlesnakes eat mice (predator - prey), but Gazzelle are eaten by Coyotes, and there's no arrow showing Rattlesnakes eating Gazzelle. So B is incorrect.
• Option C: Brittlebush is a producer (plant), so it gets energy from photosynthesis (sunlight), not from Jack Rabbits and Mice (which are consumers). So C is incorrect.
• Option D: From the food web, Scorpions eat Crickets (arrow from Cricket to Scorpion), and Rattlesnakes eat Scorpions (arrow from Scorpion to Rattlesnake), so Scorpions consume crickets and are prey to rattlesnakes. This matches the food web relationships.

Answer:

D. Scorpions consume crickets and are prey to rattlesnakes.
