Question

The taiga is a forest region in the northernmost part of the world. This region is very cold, and winters are long. Most of the trees there are conifers, and many keep their green needles all year-round. Why do you think the needles are important for the trees’ survival?

Answer 1

The Taiga is one of the three main forest biomes. The other two are the temperate forest and the tropical rainforest. The taiga is the driest and coldest of the three. The taiga is sometimes called the boreal forest or the coniferous forest. It is the largest of all the land biomes.

What makes a forest a taiga forest?

The taiga has several characteristics that distinguish it from the other forest biomes: Evergreen trees - This forest is covered with evergreen, or coniferous, trees. These are trees that don't drop their leaves, or needles, in the winter. They keep their leaves so they can soak up as much sunlight for as long as possible. The dark green color of their leaves also helps them to soak up more sun and gain more energy through photosynthesis.

1. Cold weather - The taiga has the coldest weather of the forest biomes. Winters can get as cold as -60 degrees F. Winter can last for six months with the temperature averaging below freezing. Summers are warmer, but very short.
2. Dry - The precipitation is only slightly more than the desert or the tundra. Average precipitation is between 12 and 30 inches per year. It falls as rain in the summer and snow in the winter. Thin layer of soil - Because the leaves don't fall from the trees, like in the temperate forest, the layer of good soil is thin. Also, the cold weather causes a slow rate of decay taking it longer for nutrients to get back into the soil.
3. Short growing season - With a long winter and short summer, plants don't have a lot of time to grow in the taiga. The growing season only lasts for around three months. This compares to at least six months in the temperate forest and a year round growing season in the rainforest.

Answer 2

Answer:

since needle don't shed each fall they can capture sunlight for the entire year.needles can survive ice and snow.needles have lower wind resistance and not like falt usual leaves such that tree will not fall during wind. insects can't eat needles.
