Answer
Trampling can lead to reduced feed availability, affecting the health and nutrition of livestock. This damage decreases the carrying capacity of the camp, as less feed means fewer animals can be supported sustainably.

Answer
Point A on the graph indicates the level of fertilizer application at which there will be no extra profitable income. Beyond this point, increasing fertilizer application does not lead to an increase in yield, and the farmer may start losing money due to increased costs.
