---

#### 1. Refers to the movement of oxygen through the atmosphere, biosphere, and the lithosphere.
- Correct Answer: C. oxygen cycle
- Explanation: The oxygen cycle describes how oxygen moves and is cycled through the atmosphere (air), biosphere (living organisms), and lithosphere (Earth's crust). This includes processes like photosynthesis, respiration, and decomposition.

#### 2. The arrows between organisms in a food chain or food web that show the flow of energy. The arrow points to the organism that is receiving the energy.
- Correct Answer: A. flow of energy
- Explanation: In a food chain or food web, arrows indicate the direction of energy transfer. Energy flows from one organism (producer or consumer) to another as they eat or are eaten.

#### 5. Life cycle of many insects with four stages: egg, larva, pupa, adult.
- Correct Answer: C. complete metamorphosis
- Explanation: Complete metamorphosis is a life cycle found in insects like butterflies and bees, which go through four distinct stages: egg → larva (caterpillar) → pupa (chrysalis) → adult.

#### 7. Two or more substances put together that can be easily separated.
- Correct Answer: D. mixture
- Explanation: A mixture is a combination of two or more substances that are not chemically bonded and can be separated physically. Examples include saltwater or air.

---

#### 8. An organism that makes its own food using energy from the sun through a process called photosynthesis.
- Correct Answer: D. producer
- Explanation: Producers, such as plants and algae, use sunlight to produce their own food through photosynthesis. They form the base of most food chains.

---

#### 9. To sort into groups by characteristic or property.
- Correct Answer: A. classify
- Explanation: Classification involves grouping things based on shared characteristics or properties. Scientists classify living organisms into categories like kingdom, phylum, class, etc.

---

#### 10. An organism that breaks down dead plants and animals. This allows nutrients to go back into the soil to be reused.
- Correct Answer: B. decomposer
- Explanation: Decomposers, such as bacteria and fungi, break down dead organic matter, returning nutrients to the soil and completing the nutrient cycle.

---

#### 11. All living and nonliving things that interact with each other in an environment.
- Correct Answer: D. ecosystem
- Explanation: An ecosystem consists of all the living organisms (biotic factors) and nonliving components (abiotic factors) in a specific area, interacting with each other.

---

#### 12. Solid, liquid, and gas.
- Correct Answer: C. states of matter
- Explanation: The three primary states of matter are solid, liquid, and gas. These describe the physical forms in which matter can exist.

---

#### 13. Any living thing.
- Correct Answer: A. organism
