What is one way a dead bird recycles carbon into the carbon cycle?

• Bacteria break down molecules in animal into carbon - based soil nutrients
• Animals release oxygen that is used by bacteria to produce carbon dioxide.
• Animals release carbon dioxide that is used by bacteria for growth and reproduction
• Bacteria combine carbon - based nutrients from plants and animals to produce glucose.

Mangrove trees are common to the Florida Everglades.  The tree roots serve as a place for freshwater oysters to attach when the tide is high.  The oysters are protected from predators when attached to the roots underwater.  The oysters do not harm the trees nor do they provide any benefits to the trees.

Which of the following relationships is most similar to the relationship between the mangrove trees and the oysters?

• African ants living in acacia trees feed on leaf - eating insects found on the tree.
• Spider crabs are camouflaged by the green-brown algae growing on their shells.
• A whale is unaffected by the attached remora fish feeding on the whale’s leftover food.
• Bees fly from one flowering plant to another gathering nectar and pollinating the flowers.

Food webs show feeding relationships among different types of organisms. Those organisms each have a specific niche (role). Which of the following best describes a function of decomposers in food webs?

• to recycle nutrients into soil
• . to convert solar energy into food
• . to provide food for secondary consumers
• to compete with secondary consumers for oxygen

A certain reptile species is an herbivore and exists only on an isolated island.  Which of the following would most likely result in the extinction of the reptile species over a period of twenty thousand years?

• The reptile species produces many offspring with many unique traits, and the vegetation remains constant.
• The reptile species produces few offspring with some unique traits, and the vegetation remains constant
• The reptile species produces few offspring with  no unique traits, and the vegetation changes quickly to protect itself from the reptile species.
• The reptile species produces many offspring with some unique traits, and the vegetation changes slowly to protect itself from the reptile species.
