The mechanism is straightforward: in Metaphase one of Meiosis, chromosomes line up in two lines, with homologous across from each other, which allows them to interact by crossing over. In Metaphase of Mitosis, the chromosomes are all lined up single file, so the homologous chromosomes cannot interact.

Althogh options are not given for this question, here is what I can speculate based on provided limited information.

For the second part I can say that temperate grasslands have primary vegetation (grasses) whereas other biomes have higher plants as well.
