The following choices are provided;
- Earthquakes release phosphorus.
- Phosphorus is carried in the rain that was evaporated from lakes.
- Human use of fertilizers releases phosphorus into the groundwater.
- Phosphorus is transpired.
The answer is; Earthquakes release phosphorus
Phosphorus is usually made less available to plants and to the rest of the ecosystem through runoffs. The washed-off phosphorus is deposited at the oceans- and seabeds with sediments. This phosphorus is made available again due to tectonic plate movements. Tectonic movements may cause earthquakes that expose these sediments to the earth’s surface.This uncovers the sedimentary rocks to agents of weathering and hence the elements are more available to living organisms on the surface.
Answer:
Electrons Can Donate - 0
Electrons Can Receive- 2
Valence - 2
Explanation:
The electronic configuration of oxygen is 
. Thus in the p-orbital there is deficiency of two electrons. Hence, it can receive/share electron but it cannot donate electrons. This makes oxygen as a good electron acceptor. Since there is a deficiency of two electrons in the outermost shell of oxygen, the valence of oxygen in thus -2
