What is a biogeochemical cycle? Why is the cycling of nutrients essential to the continuance of life? 2. Be able to identify and describe each step in the C, N, S, H, O, K, and Rock cycles. 3. List and briefly explain three ways in which humans and wildlife are influencing each biogeochemical cycle. 4. Describe how organisms participate in each of the biogeochemical cycles. Explain why organisms are important to some of the BGC cycles and less important in other cycles.
Understand the Problem
The question is asking a series of questions related to biogeochemical cycles, including what they are, specific steps in certain cycles, their significance, and the role of organisms in these processes.
Answer
1. Biogeochemical cycles move elements through ecosystems, vital for life. 2. Key cycles: carbon, nitrogen, sulfur, etc. 3. Humans affect cycles via pollution, deforestation. 4. Organisms participate through processes like photosynthesis; crucial in some cycles.
- A biogeochemical cycle is the movement of elements through living organisms and the environment. Nutrient cycling is essential for maintaining ecosystem balance and supporting life. 2. Describe each cycle's processes, such as photosynthesis, decomposition, and weathering. 3. Human influences include pollution, deforestation, and agriculture affecting cycles. 4. Organisms like plants and bacteria play critical roles, such as fixing nitrogen or producing oxygen.
