Question

In the phosphorus cycle, phosphorus can recycle through waste products, decomposition, and _______ of terrestrial and aquatic ecosystems.

Answer 1

Answer is - Assimilation

Reasoning - photosynthetic organisms such as Algae or Plants assimilation phosphorus into their cell. Which they later transfer it to animals whom consume which then starts the cycle.

Answer 2

Assimilation

Step-by-step explanation:

The phosphorus moves in a cycle through rocks, water, soil, sediments, and organisms. The principle steps of the cycle are:

• Over time, rain and weathering cause rocks to release phosphorus ions (phosphate) at the environmental. These ions are distributed in soils and water;
• Plants take up the ions from the soil, and animals can have it by consuming these plants, or in the water. This process is assimilation. The phosphate is incorporated into organic molecules such as the DNA;
• When the plants and the animals die, the decomposition releases the phosphorus on soil;
• The phosphorus can reach waterways and eventually the ocean, where it can be incorporated in sediments.
