GCSE Biology Question Analysis Topic: Biology - Reservoirs
Exam Question:
State the function of a reservoir in a nutrient cycle. Explain the simplified model of carbon cycle in nature.
Answer:
For GCSE Biology, you should know:
The role of a reservoir in a nutrient cycle is to fill the deficit caused by imbalances in the state of nutrient influx and efflux.
The carbon cycle:
1) Combustion (burning) and respiration (breathing) release carbon into the atmosphere as carbon dioxide.
2) Through the process of photosynthesis, producers absorb carbon dioxide to make carbohydrates. Then, these oxygen producers release oxygen.
3) Plants are eaten by animals. They consequently transmit the carbon compounds up the food chain. However, the majority of the carbon that these creatures consume is exhaled as carbon dioxide. This is accomplished through respiration. Then, the animals and vegetation eventually die.
4) The ground's decomposers consume the deceased organisms. The carbon that was once in their bodies is then released as carbon dioxide back into the atmosphere. The process of decomposition can be stopped in some circumstances. In the future, the decomposed plants and animals might be used as fossil fuels.
Work hard for your GCSE Biology examination!
End of analysis. Great!
