Which of the following statements about biogeochemical cycles is not true?
a. biogeochemical cycles include living and nonliving elements.
b. the rock cycle is a biogeochemical cycle.
c. biogeochemical cycles are an important part of the earth system.
d. carbon, nitrogen, and oxygen cycles are biogeochemical cycles.

B.  The rock cycle is a biogeochemical cycle. (not true)

The rock cycle is a biogeochemical cycle is an incorrect statement regarding the biogeochemical cycle.

Further Explanation:

In Biogeochemical cycles, chemical elements are recycled. These elements may accumulate in sinks and detain for a long time. This is a cycle by which a chemical molecule or element circulates through the non-living and living constituents of an ecosystem.

Nitrogen, hydrogen, carbon, and oxygen are the key components in a life of organisms. Therefore, oxygen, nitrogen, and carbon cycles are kind of biogeochemical cycles.

Rocks are aggregates of minerals and majorly of three types:

The rock cycle is a kind of illustration that helps in explaining how the three different kinds of rocks are associated with others and how the Earth processes modification in the different rocks. Modification in the rocks is developed to movement in tectonic plate movement. They recycle rock materials.

emerald ash borer

the emerald ash borer is a green buprestid or jewel beetle native to north-eastern asia that feeds on ash species. females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years. hope this !
