Question

The tundra is characterized by extremely low temperatures as well as little precipitation, a rocky landscape, and permafrost. Because of these physical features, what type of producers would we expect to find in the tundra?
A) lichens and low-growing moss
B) conifers, trees with needles and cones
C) leafy plants like ferns and deciduous trees
D) deciduous trees, that lose their leaves in the fall

Answer 1

Answer: A). lichens and low-growing moss

The tundra is characterized by extremely low temperatures as well as little precipitation, a rocky landscape, and permafrost. These physical features does not support a landscape with healthy vegetation. This will be a primitive landscape as it cannot support growth of large trees. Lichens and low-growing moss are organisms which can grow in these rocky permafrost substrates. Lichens will release acids which will make the ice melt and can cause withering of rocks into small particles of soil. The available soil on rock surface can facilitate the growth of small mosses.  

Answer 2

Because of these physical features, the type of producers that we would expect to find in the tundra are A. lichens and low-growing moss.
Because it is usually very cold in the tundra, and there isn't much rain, but there are a lot of rocks around with no grass, the plants that will grow in such a place have to be small plants because they don't have the appropriate conditions to grow and thrive.
