Biomass is often referred to as a measure of the living matter in a particular area. They absorb their nutrients and moisture directly through their leaves. Adaptations are natures way of helping animal and plant populations survive in a particular biome. Warming temperatures could disrupt the cold tundra biome and the life in it, as well as thaw its underlying permafrost, releasing greenhouse gases that would further accelerate global warming. An even bigger problem is that carbon is released when the permafrost melts.

The hairy flower stalks of cottongrass (Eriophorum), lousewort (Pedicularis), and willows retain warm air, raising the temperature near the stalks by 39 C (515 F); this ability is an important adaptation for flowering in areas where air temperatures may approach the freezing point. arctic willow has adopted to the tundra conditions very well.

Like other mosses, arctic moss has tiny rootlets instead of traditional roots, only they have found interesting ways to adapt to their exceptionally cold climate. The larger and taller they grow, the more they can influence soil temperatures and thaw the permafrost layer, or even change the soils nutrient cycle and carbon levels (affecting decomposition and the amount of CO2 released into the atmosphere). They are adapted to climbing up other plants to reach sunlight in the rainforest canopy. 2023 Leaf Group Ltd. / Leaf Group Media, All Rights Reserved. The plants living in the tundra are hardy plants. Dr. Mary Dowd studied biology in college where she worked as a lab assistant and tutored grateful students who didn't share her love of science.
