B. The desert's dry environment
While cacti have managed to survive in the high temperatures of the day, the lower temperatures at night, and the sandy desert soil composition, one of the most defining features about their cacti is their unique ability to store and preserve water. Most variants of cacti lack leaves, which reduces the loss of water by reducing transpiration. Cacti also have roots that are spread out widely in order to collect as much water as possible. This water is then stored in large storage areas which can be located in the roots or the body of the plant.
D. Mimicry
Mimicry is when an organism mimics another organism. In this example, the fish swim in schools to <em>mimic </em>the appearance of a larger organism in hopes of discouraging predators.

By including salad and mashed potatoes in his meal, Blair is being a primary consumer as he is eating producers (the lettuce and potatoes). The steak, which must've come from a cow, then confirms that Blair is a secondary consumer. However, since Blair has no natural predators that threaten him, he would be considered a tertiary and quaternary consumer. This is because humans not only sit at the top of their food chain, but they also will consume other tertiary predators.

B. A decrease in robins
