Answer:
The correct answers to these questions, and their explanations, are thus:
1. Rainforest: Dense vegetation with little sunlight reaching the ground. Rainforests are peculiar in that most people term them as jungle. Thier characteristic is that they tend to be very humid and rich in rainfall, and their vegetation tends to be very dense.
2. Tundra: Coldest biome with scarce vegetation. This biome is known because there is very little tree, or even plant, growth due to the very low temperatures in it. Also, the growing seasons in this biome are very short.
3. Grassland: Open spaces with grass, but few trees. Grassland is described exactly as a vast expanse of land where the predominant feature is an abundand amount of grass, but very little other vegetation.
4. Taiga: Largest biome with abundant rainfall and snow. The taiga is known as the largest biome, and it can usually be found in regions such as North America. It is also known as the boreal forest. It is characterized by the types of trees found there, like conifers, and the amount of frigid water, and snow, that falls on it.
