This turtle is an example of a heterotroph. It depends on other organisms to make its food. An organism that makes its own food is called an autotroph. Other examples of heterotrophs are deer, rabbits, cows, goats, horses, and any other herbivore.

This flower is an example of an autotroph. It makes its own food by using carbon from inorganic molecules, such as energy from light and chemical reactions. All plants are autotrophs. The flower in this picture is a dusty miller.

Black-eyed Susans are an example of long-day plant. They are plants that require more than six hours of sunlight a day. Other examples are lettuce, spinach, and potatoes.

An example of commensalism is birds building their nests in trees. Commensalism is when one species benefits from the interaction but the other one is neither helped nor harmed. In this case, the bird is benefited and the tree isn't helped or harmed.

Crabs are an example of bilateral symmetry. This means the body plan of the crabs would be exactly the same if cut in half. All of the organs are paired, one to each side of the body. Humans are also an example of bilateral symmetry.
