Some plants are so low and densely packed that they deserve the name "cushion plants." Just like all the other plants inhabiting tundra, they are well adapted to resist heavy winds and soil disturbances. Food and feeder relationships are simple, and they are more subject to upset if a critical species disappears or decreases in number. Plant and Animal Adaptations .
