Likewise, the blood drinking of the sharp-beaked ground finch could be a natural extension of foraging for invertebrates: a misdirected or inadvertently strong peck might well be rewarded with blood, and eventually the accident becomes a habit. For example, cacti are able to store water because they live in dry places, and they have spines to discourage animals from eating them. Overproduction - there are more organisms born than the environment can support 2. About 20 to 30% of the variation of milk yield is explained by variation of body weight. Briefly explain each 1.)
