01 Why is tree growth generally limited in tundra climate?
Answer and explanation
Correct answer: B. Low temperatures and a very short growing season
Explanation: Tundra regions remain very cold for most of the year, and the brief summer provides only a short growing season. Frozen ground or permafrost can also restrict deep root development and drainage. These conditions allow mosses, lichens, grasses, and low shrubs, but usually not tall trees. Extreme heat, industry, and trade are not the general climatic reasons for the lack of trees. Hence B is correct.
