Ответ:
Sea urchins? Is it multiple choice?
Ответ:
sea urchins
Explanation:
sea urchins may be vulnerable to increasing acid levels in the ocean. Ocean acidification could interfere with the urchins' ability to transform calcium, magnesium and other minerals from seawater into their “tests” (the white shell left when the animal dies), spines and teeth.
Ответ:
It needs the spines for protection
Explanation:
The cactus would develop the spines as a form of protection to protect itself from being consumed and to survive longer.
