Other than humans, insects also interact with this plant. The
bumblebee has a mutualistic relationship with the cactus in that
the bee feeds on the sweet sap of the plant and in doing so
spreads pollen from the flower. Some birds also tend to eat the
fruit of the plant. This consumption of the fruit helps spread
the seeds so more plants can grow. To learn more about how these
