(Q).
Answer the following question given this paragraph: When organisms die, they leave behind energy and matter in their remains. Decomposers break down the remains and other wastes and release simple inorganic molecules back to the environment. Producers can then use the molecules to make new organic compounds. The stability of decomposers is essential to every ecosystem. Decomposers are classified by the type of organic matter they break down:. Q: What do decomposers release back to the environment after they break down the remains and other wastes? Choices: - carbon monoxide - unrefined waste - nematodes - simple inorganic molecules A:
(A).
simple inorganic molecules

(Q).
Answer the following question given this paragraph: Blood flows through the heart in two separate loops. You can think of them as a "left side loop" and a "right side loop. " The right side of the heart collects oxygen-poor blood from the body and pumps it into the lungs, where it releases carbon dioxide and picks up oxygen. The left side carries the oxygen-rich blood back from the lungs into the left side of the heart, which then pumps the oxygen-rich blood to the rest of the body. The blood delivers oxygen to the cells of the body and returns to the heart oxygen-poor. Q: The right side of the heart collects what type of blood from the body? Choices: - oxygen-rich - dioxide-poor - potassium-rich - oxygen-poor A:
(A).
oxygen-poor
