Study Notes
Carbon and Living Organisms
- Carbon is an element, symbolized as C
- Carbon exists naturally in different forms, including graphite and diamonds
- Living organisms need carbon, but not in its pure form
- Carbon is a part of many compounds crucial for cell function, such as carbohydrates, proteins, and fats
Photosynthesis and the Carbon Cycle
- Plants use carbon dioxide from the air in photosynthesis to create carbohydrates
- Carbohydrates in plants contain carbon atoms originally from the air
- Animals obtain carbon by consuming plants or other animals
- Decomposers break down waste, releasing carbon back into the environment
- A flow diagram can illustrate how carbon moves through plants, animals, and decomposers
Questions
- Question 1a: Draw a simple food chain including a plant and animals
- Question 1b: Arrows in a food chain show energy transfer, not necessarily the movement of carbon atoms; explain how energy and carbon atoms move.
- Question 2: Human bodies contain several carbon-containing compounds; provide examples.
