1. Living things can inherit behavior, learn it from other creatures, or change their behavior because of their environment. Which example describes learned behavior in a living thing?
A. A sea turtle that hatches on a beach will crawl toward the ocean.
B. Most humans begin to speak when they are one or two years old.
C. Fireflies can produce light from their abdomens to attract mates.
D. Sunflowers are able to turn to face the Sun to help them grow.
Explanation: Speaking is a learned behavior that must be taught by one human to the next.2. Animals which share the same space must compete for resources. Which answer is the best example of this?
A. The cattle egret will stay close to grazing animals. When grazing animals move, they stir up insects, which the egret then eats.
B. Some species of orchid look like a female bee. This attracts male bees, who leave pollen so that the orchid can reproduce.
C. Humans cut down forests and built roads in the Florida Everglades. The Florida panthers living there had less territory and their population declined.
D. Rhesus monkeys were released into the wild along Florida's Silver River. The monkeys have adapted to the environment and have lived there for over eighty years.
Explanation: In their search for food, animals are in competition with others in their own species, as well of those in other species. This is a constant practice within the environment in order to sustain and thrive within a given environment.3. In the savannahs in Africa, elephants and giraffes both use acacia trees for food. What impact would removing these large animals from the savannah most likely have on the surroundings?
A. The population of acacia trees would decrease.
B. The trees would begin to take over and there would be less grass.
C. The population of smaller animals would take over because there would be no predators.
D. The large animals in other areas would migrate to the area and eat all of the trees on the savannah.
Explanation: By removing the animals from the savannah. The effect would be an increase need in the number of trees. There would be an abundance of trees when they are not being kept under control by the elephants and giraffes.4. The American Black Bear lives in many parts of North America. A black bear in Colorado might hibernate for three or more months in winter, while a black bear in Florida may hibernate for only a few weeks, or not at all. Which statement best explains why?
A. Florida black bears are a different species from Colorado black bears.
B. Florida black bears hibernate less because their climate is not as cold.
C. Florida black bears have less territory and cannot risk a long hibernation.
D. Florida black bears eat different food from bears in Colorado and need less rest.
Explanation: Black bears are able to adapt in many environments. Because of this, the black bears that are in the colder environments will store food and hibernate to adapt within the winter, whereas a black bear found in Florida will not have to store food nor will It have to hibernate during the cold as it does not apply to its environment.5. Two animals that live in Florida are the American bittern and the Key deer. The bittern is a bird that has a buff and brown colored back that allows it to blend in with the sawgrass of the lakes it lives near. When it feels threatened, the bittern freezes and points its head skyward to resemble a reed. The Key deer is brown in color, lives in the forest, and freezes when it feels threatened. How do these two animals use similar adaptations in order to survive in their very different environments?
A. Both the bittern and the deer use their small size to hide from approaching predators.
B. Both animals live in groups and huddle together with their family for protection from predators.
C. Both animals use their coloring and lack of big movement to avoid being seen by predators.
D. Both the bittern and the deer use the movement of the trees and bushes around them to distract predators so they can escape.
Explanation: I know that animals use structural adaptations such as color and movement to adapt and survive. The bittern uses its color to blend in with the sawgrass within its environment. Similarly the key deer also brown, but lives in the forest and is able to blend in with the surrounding trees and brush within the forest
