AP BIOLOGY

Detailed explanation-1: -Organisms use camouflage to mask their location, identity, and movement. This allows prey to avoid predators, and for predators to sneak up on prey. A species’ camouflage depends on several factors. The physical characteristics of the organism are important.

Detailed explanation-2: -Predator: an animal that kills and eats other animals. Context: Hawks and coyotes both eat small rodents; they are predators. Prey: animals that are killed and eaten by other animals.

Detailed explanation-3: -Such species are called semelparous. Semelparity is a reproductive strategy in which individuals only reproduce once in their lives and die soon afterward. Examples such as salmon, octopus and marsupial mice all die rapidly after reproduction.

Detailed explanation-4: -Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit. The words “predator” and “prey” are almost always used to mean only animals that eat animals, but the same concept also applies to plants: Bear and berry, rabbit and lettuce, grasshopper and leaf.
