Why are conifers so common in American forests?
tiny-mole [99]

Answer:

Answer is C

Explanation:

Coniferous forests grow in a wide range of climates, from the coldest polar regions to the warmest tropical regions and everything in between.

Conifer trees are adapted for cold and harsh climates. ... The needle-like leaves are an important adaptation to Conifer trees because they do not accumulate much snow, keeping the weight load mild. Even though Tamarack trees lose their leaves in the winter, they are still subject to some snowfall.
