what do living things use for fuel
Answers
Answer:
Using energy from light, carbon dioxide and water, these organisms, known collectively as producers, are able to make carbohydrates, which serve as fuel and raw material for the processes of life. All other organisms (consumers) rely on producers for food. Food provides energy and needed raw materials.
Explanation:
Some living things, especially plants and algae, are able to build all the materials they need from very simple substances. Using energy from light, carbon dioxide and water, these organisms, known collectively as producers, are able to make carbohydrates, which serve as fuel and raw material for the processes of life. All other organisms (consumers) rely on producers for food. Food provides energy and needed raw materials.
When organisms consume food, it is broken down to release energy and to obtain building blocks for other molecules. During this process, oxygen is consumed and some carbon is given off as carbon dioxide. This can be compared to the burning of fuels, which also uses oxygen and releases carbon dioxide. When something burns, most of the energy released is given off as heat. Inside living things, some of the energy is used to maintain the body and conduct reactions necessary for life.
All organisms (with a few exceptions) release carbon dioxide when they use food. In mammals, the released carbon dioxide is carried through the bloodstream to the lungs, where it is given off when we breathe out (exhale).
In this activity, students observe how carbon dioxide gas is given off by yeast cells, when the cells use sugar as food. Red cabbage “juice” will serve as an indicator for the presence of carbon dioxide. Cabbage “juice” turns bright pink in the presence of acids, such as the carbonic acid produced by dissolved carbon dioxide in water.
Answer:
food and water
Explanation:
as all the living things need food and water to stay alive
