Mutualism between fungi and coniferous trees is most common in what biome?

Mutualism between fungi and coniferous trees is most common in the forest biome.

Explanation:

Beneficial interaction between two organisms of two different species in which both the organisms take benefit from each other in some way from this interaction. This beneficial interaction is called mutualism. Fungi and coniferous trees form interaction which is beneficial for both the species. In this interaction, the fungi help in the production of new root tips and plant provide shelter and nutrition to the fungus.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
