Question

In phosphorus, cycle phosphorus enters an ecosystem, during which of the following processes?
(a)Weathering
(b)Respiration
(c)Photosynthesis
(d)Nitrification
(e)Condensation

Answer 1

They are the breakdown and decay of rocks in place. It is often a really elongated slow procedure, taking many years. They will even be rapid, as the damage to pavements or roads after a chilly, frosty winter.

Complete answer:
In phosphorus, cycle phosphorus enters an ecosystem, during which the subsequent process of weathering. Weathering is the breakdown of rocks into smaller particles by the action of varied environmental factors like wind, water, sunlight, etc. Weathering occurs in place (i.e., on-site, without displacement), that is, within the same place, with little or no movement. There are two important classifications of weathering processes which are physical and chemical weathering; each sometimes involves a biological component. Physical weathering involves the breakdown of rocks and soils through direct contact with atmospheric conditions, like heat, water, ice, and pressure. The second classification is chemical weathering, including the straight effect of atmospheric chemicals or biologically released chemicals also referred to as biological weathering within the breakdown of rocks, soils, and minerals.

Additional Information: Respiration is the process by which living organisms derive energy by the oxidation of varied complex organic substances.
Photosynthesis is the process by which green plants capture solar power and convert it into light energy.
Nitrification is the changing of ammonia into nitrates and is carried out in two steps, nitrite formation, and nitrate formation.
Condensation is the process by which gas changes into liquid drops.
Since rocks are made from phosphorus and contain phosphates, their weathering will cause the dissolution of phosphates within the soil and thus, phosphorus enters the ecosystem.
So, the correct answer is 'Weathering'.

Note: Phosphorus is an important nutrient found within the macromolecules of humans and other organisms, including DNA. Phosphorus is usually the limiting nutrient, or nutrient that's most scarce and thus limits growth, in aquatic ecosystems. Additionally, many of Earth's landforms and landscapes are the results of weathering processes combined with erosion and re-deposition.
