text_A: There are two types of polar climate: ET and TY, or tundra climate; and EF, or ice cap climate. A tundra climate is characterized by having at least one month whose average temperature is above, while an ice cap climate has no months above. In a tundra climate, trees fail to grow, but other specialized plants can grow. In an ice cap climate, no plants can grow, and ice gradually accumulates until it flows elsewhere. Many high altitude locations on Earth have a climate where no month has an average temperature of or higher, but as this is due to elevation, this climate is referred to as Alpine climate. Alpine climate can mimic either tundra or ice cap climate.
text_B: Would ground-dwelling herbivorous insects in the tundra have anything besides dead leaves to feed on?
YES.
