Which of these is not a nutrient cycle? Water cycle
Carbon Cycle
Phosphorus Cycle
Nitrogen Cycle

The following are some of the most important biogeochemical cycles: (1) the water cycle (2) the carbon-cycle (3) the cycling nitrogen (4) the cycle of oxygen. The producers of an ecosystem use several basic non-viving inorganic nutrients.

Explanation:

Moving and exchanging organic and inorganic substances into the synthesis of the matter is a nutrition cycle (or ecological recycling). Energy flow is a one-way and non-cyclical channel, while the mineral nutrient transfer is cyclical. Mineral cycles comprise carbon, sulfur cycle, nitrogen cycle, water cycle, phosphorus, and oxygen cycle, which are continuously recycled to productive ecological nutrition along with other mineral nutrients.

the dark variety, as they are not visible on the dark tree barks

explanation:

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
