I believe the answer is all of the above
Explanation:
Phosphorus moves in a cycle through rocks, water, soil and sediments and organisms.
Key steps of the phosphorus cycle:
# Over time, rain and weathering cause rocks to release phosphate ions and other minerals. This inorganic phosphate is then distributed in soils and water.
# Plants take up inorganic phosphate from the soil. The plants may then be consumed by animals. Once in the plant or animal, the phosphate is incorporated into organic molecules such as DNA. When the plant or animal dies, it decays, and the organic phosphate is returned to the soil.
# Within the soil, organic forms of phosphate can be made available to plants by bacteria that break down organic matter to inorganic forms of phosphorus. This process is known as mineralisation.
<span># Phosphorus in soil can end up in waterways and eventually oceans. Once there, it can be incorporated into sediments over time.</span>
<span>The plant holds reserves of starches and sugars in its system during the times in which it has access to light. During periods of darkness, it will access these reserves if there are no other forms of light available or accessible.</span>
A scientific theory<span> is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported </span>theories<span> are not "guesses" but reliable accounts of the real world.</span>
For the generalized scheme of Alternation of generations (see p. 120), plants have two forms based on a genetic complement that are the Sporophytes (2N diploid) and Gametophyte (N haploid). The processes connecting the two stages are gametangia producing haploid spores and zygote cell growth producing haploid gametophyte. Group of answer choices
