Question

Expain the following.(i) Phosphorus cycle(ii) Pyramid of energy.

Answer 1

1)....Phosphorus is an essential element to all life. It is an important part of the ATP molecule that stores and gives every cell its energy. It is also found in DNA and RNA, which tell the cells how to look and act. Needless to say, phosphorus is needed for every living organism to grow and function. The phosphorus cycle is the process in which phosphorus travels from its main source of rocks through ecosystems to living organisms


2.)... An ecological pyramid is a graphical representation designed to show the biomass or bio productivity at each trophic level in a given ecosystem. Biomass pyramids show how much biomass is present in the organisms at each trophic level, while productivity pyramids show the procreation or turnover in biomass.
