The correct answer is:

A) True

Explanation:

All cycles such as carbon cycle, water cycle, nitrogen cycle, oxygen cycle, phosphorus cycle and many more are very important for all living organisms because these all cycles are assigned with the core activities for the life and ecosystem as well. Such as Carbon is released from a cycle in the form of carbon dioxide through the process of respiration of all living organisms, All the living organisms need water to grow and survive and they get this water stored deep down the Earth as a result of the water cycle. Similarly, nitrogen is an important part of many cells and processes such as amino acids, proteins, and DNA. plants need nitrogen in the process of photosynthesis to get food. Oxygen is important for respiration. phosphorus is important for nutrients for plants and animals. So, all cycles have their own very important part for life.
