Question

review it!
the cactus and thorny devil live in the desert.
they both have spiky structures.
what is the function of the structure?
protection from predators
blend in with environment
finding food
storage of water

Explanation:

The spiky structures of cactus (thorns) and thorny devil are primarily for protection. Thorns on cactus deter herbivores, and the spiky body of thorny devil discourages predators. Blending in (camouflage) is not the main function of spines/thorns here, finding food is unrelated, and water storage is for cactus stems (not spines) and not relevant for thorny devil's spiky body. So the correct function is protection from predators.

Answer:

A. protection from predators
