Carbon's role in living organisms

Carbon is a crucial element, forming part of many compounds like carbohydrates, proteins, and fats essential for life processes in cells.

Photosynthesis's function

Plants use carbon dioxide from the air to make carbohydrates through photosynthesis.

Carbon cycle in animals

Animals consume plants or other animals, transferring carbon atoms through the food chain.

Carbon compounds in the body

The human body contains many compounds with carbon atoms serving essential functions.

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.
