maxonik [38]

Answer:

The interaction between the sloths and the leaves they eat is an example of a<u> predator-prey</u> relationship. In this example, sloths are <u>herbivores</u> that acquire their nutrients and energy from the<u> plants</u> they eat. The colors of coral snakes provide these animals with <u>mimicry</u> to avoid predation. Specifically, their coloration helps them <u>advertise their toxicity.</u> The interaction between the hosts and the ticks that live on them can be characterized as <u>parasitism</u>, because <u>one species feeds on the other</u>.

Explanation:

Predator-prey relationships are those in which a specie feeds on another specie. The sloth is the predator that feeds on the leaves which are its prey. Herbivores feed on plants. Therefore, the sloth are rightly classified as herbivores.

Coral snakes are brightly colored with red, yellow, and black patches that warn potential predators of their toxicity. Ticks living on hosts are parasitic because the ticks feed on their host.
