Homework Answers
Option A : Not true
Explanation: Depletion zone for minerals means a zone which is responsible for emitting the mineral contents. Now, according to the modus operandi of that fungi, it helps to uptake all the minerals like P, N, K, Zn etc. So, it is clear that this fungi definetely do not increase the depletion zone. Rather it decreses the depletion zone. So that, minimum minerals are lost and maximum minerals are kept inside.
Other 4 options are correct.
