Nutrient cycling in nature: WAEC Biology Past Questions and Answers
What the WAEC syllabus covers in Nutrient cycling in nature
Our summary: How carbon and water cycle through living things and the environment.
- Carbon cycle: process of carbon cycle; importance of carbon in nature (Candidates should be able to draw the carbon cycle, list the sources of carbon (burning, respiration, decay) and discuss the relative importance of the cycle. Reference should be made to carbon dioxide-oxygen balance in nature. Candidates should carry out experiments to show absorption of carbon dioxide and release of oxygen during photosynthesis.)
- Water cycle: importance of water cycle; importance of water to living organisms (Candidates should carry out experiments to show the presence of water in expired air and that water is given off during respiration.)
