Verified step by step guidance1
Understand the concept of biogeochemical cycles, which describe the movement of elements through different parts of the Earth, including living organisms and the environment.
Identify the elements in question: calcium and phosphorus. These elements are essential for biological processes and are cycled through ecosystems.
Recognize that abiotic reservoirs are non-living components of the environment where elements are stored. These can include the atmosphere, bodies of water, and soil.
Consider the characteristics of each potential reservoir: Oceans and rivers are primarily reservoirs for water and dissolved substances, the atmosphere is a major reservoir for gases, and soil is a reservoir for minerals and nutrients.
Conclude that soil is the main abiotic reservoir for calcium and phosphorus, as it contains minerals and nutrients that are cycled through local ecosystems.
