PLEASE MARK ME AS A BRAINIEST
Explanation:
1)These spine clusters almost act like mini-umbrellas that help to shade the plant. By shading the cactus, these spines also help prevent the cactus from losing water through evaporation. So all in all, spines are adaptations that protect and help cacti hide from animals that may want to eat them.
2) Ducks have an elongated, flattened bill shape. This spatulate shape helps the birds crush food similar to teeth, but without the same strength for pulverizing tough foods, and ducks don't repeatedly chew as they eat. The spoon-like shape also helps ducks filter food from water, sand, or mud
3)The conical shape of trees prevents as much accumulation of snow as there would be on broader shapes. The conical shape of the tress also help to get the snow fall very quickly and to get the sunlight which help the trees to adapt in that environment.
4)Inhabiting the ice and sea of the Arctic, polar bears are well-equipped for survival in a harsh environment. ... Two coats of fur and a thick layer of blubber help insulate the polar bear's body from the cold, keeping its temperature at an even 37° C (98.6° F).
