On the energy flow and biogeochemical cycling within and among ecosystems. Given: Energy flow and biogeochemical cycling happen within and among ecosystems. Introduction: In an ecosystem, the transfer of energy from one trophic level to the other is known as the energy flow. It is depicted in the form of food chains and food webs. A biogeochemical cycle can be defined as a pathway by which chemical elements and compounds flow through biotic (biosphere – living components) and abiotic (lithosphere, atmosphere, and hydrosphere – nonliving components) compartments of the Earth. For example, carbon cycle, nitrogen cycle, oxygen cycle, water cycle, phosphorus cycle, and sulfur cycle.

(This is a 2-part work, Part 1 is done, only Part 2 is to be worked on at the bottom)Part 1 (Done): Describe the levels of structural hierarchy for the human body, starting with the organismal level and ending with the chemical level. In addition, you should make sure you link each level to the previous level, emphasizing the structural relationships. The human body is organized into a structural hierarchy that progresses from the macroscopic organismal level down to the microscopic chemical level. Each level builds upon the previous one, creating increasingly complex structures. Below is the hierarchy, from largest to smallest, with explanations linking each level to its predecessor: 1. Organismal Level The entire living human body.Relationship: All lower levels work together to sustain life at this highest level. 2. Organ System Level Groups of organs working together to perform major functions.Examples: circulatory, nervous, digestive systems.Relationship: The organismal…
