3. W RITE ANSWERS TO THE QUESTIONS. What is a tropism? Describe one kind of tropism. Tropism is the response of a plant to something in the environment. Phototropism: is a response to light in which the stem bends towards or away from light. Gravitropism: is a response to gravity; the roots grow down andthe stem up.

4. Define biotic and abiotic factors and give an example of each. Biotic: living organisms in the ecosystem. Ex.: Humans, animals, plants. Abiotic: nonliving parts. Ex.: sun light, air, water.

5. Explain the role of the respiratory system in keeping the body’s systems in balance. Lungs take in oxygen. Other parts of the respiratory system transfer it to the blood. Carbon Dioxide is removed from the blood and then exhaled from the body.

6. Describe two biotic and two abiotic factors in an ecosystem. Biotic: plants – they are living organisms that take in carbon dioxide and produce oxygen cleaning the air. They also serve as food for animals. Animals – they are living organisms that consume plants or other animals and serve as food for others as well. Abiotic: air– nonliving factor that all living things need the oxygen in the air to live. water– nonliving factor that cells in all living organisms need to continue living.

14. W RITE T (T RUE ) OR F (F ALSE ) ON THE LINE BEFORE EACH STATEMENT. Plants produce carbon dioxide and water in the process of photosynthesis. Most organisms depend on plants for oxygen. Glucose is produced in the mitochondria or plants. Cellular respiration occurs only in animals. Both plants and animals depend on the carbon dioxide-oxygen cycle. F T F F T
