Question

the tundra region is a cold, dry region, where the soil is permanently frozen throughout the year. this layer of frozen soil is called permafrost. the tundra grasses that provide food for herbivores like caribou and musk oxen. due to an increase in global temperatures, the permafrost is melting. it is predicted that tundra will increase by 2 to 4°f by 2100. how will the vegetation throughout the tundra be affected if no changes are made to slow the process of global warming? the vegetation will be replaced by marine plants that grow in ocean waters. the vegetation will be replaced by coniferous trees that typically grow in warmer climates. the vegetation will be replaced by desert plants that require less water to survive. the vegetation will be replaced by trees that typically grow in rainforests.

Explanation:

As global warming melts the permafrost in tundra, the soil conditions and climate will change to be warmer. Coniferous trees, which can thrive in warmer - than - tundra climates, are likely to replace the existing tundra vegetation. Marine plants grow in water, desert plants are adapted to arid non - tundra conditions, and rainforest trees need a very different and more humid environment than what tundra will become.

Answer:

B. The vegetation will be replaced by coniferous trees that typically grow in warmer climates.
