Question

more about respiration and photosynthesis
the energy - producing process in living things is called respiration. respiration is the process by which food is combined with digested food (glucose). carbon dioxide and water are also produced. they are waste products of respiration.
a simple way to show respiration is this:
glucose + oxygen → carbon dioxide + water + energy
the food - making process of green plants is called photosynthesis. photosynthesis is also responsible for the production of oxygen.
photosynthesis can be shown in this way:
carbon dioxide + water → glucose + oxygen
using the above information, answer the following questions.

1. what do we call the release of energy by living things?
2. respiration is different, the same in plants and animals.
3. two waste products produced by respiration are and
4. what fuel do living things use for energy?
5. what must link up with this fuel to produce energy?
6. do plants take in food from the outside?
7. how do plants obtain food?
8. the food - making process of plants is called

Explanation:

1. The text defines respiration as the energy - producing process in living things, so the answer is respiration.
2. Respiration is the same process in plants and animals as described in the text.
3. The text states that carbon dioxide and water are waste products of respiration.
4. Glucose is the fuel living things use for energy according to the text.
5. Oxygen must link up with glucose to produce energy as per the respiration equation.
6. Plants do not take in food from the outside in the traditional sense.
7. Plants obtain food through photosynthesis where they use carbon dioxide, water and sunlight to make glucose.
8. The food - making process of plants is called photosynthesis as stated in the text.

Answer:

1. Respiration
2. the same
3. Carbon dioxide, water
4. Glucose
5. Oxygen
6. No
7. Through photosynthesis
8. Photosynthesis
