Comparing Zagreb M1 and M2 indices for acyclic molecules

Recently, it has been conjuctured that for each simple graph with n verices and m edges, M1/n is smaller or equal to M2/m, where M1 and M2 are the first and second Zagreb index. This claim has been later disproved for connected as well as for disconnected graphs. Here, we show that this claim holds for trees.
