Which if the following is a biotic factor in a deciduous forest biome? A Temperature
B Precipitation (rain)
C Soil
D Trees
​

Explanation:

A biotic factor is a living part of an ecosystem. Animals, plants, fungi, and bacteria are all examples.

Let's examine the list we are given. We have temperature, precipitation (rain), soil, and trees.

Temperature, precipitation, and soil are not living. These are all abiotic factors. They are still part of the ecosystem, but they are not alive. So, that leaves trees, which are plants, as the biotic factor in a deciduous forest biome.

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.
