Primary Productivity
2.1: Arctic foxes are commonly found within the Tundra and are a key consumer in the chain.

Primary productivity in an ecosystem refers to how much, and how quickly its producers are able to convert chemical energy from stored solar energy. As the Arctic Tundra is a cold atmosphere, it's rate of primary productivity is different to those situated near swamps and marshes due to their conditions.
According to world-builders.org and Pearson's textbook, the Tundra received an approximate 600 kilocalories/square meters per year. This compared, to the desert is a heavy increase, this is due to the lack of water provided for vegetation. In Tundra, the frozen layer of permafrost makes it very hard for producers to grow as they would often freeze. In biomes such as Tropical Rainforest's and Estuary, the NPP is at a much higher rate. Their conditions with sunlight and water make it easily possible for plants to photosynthesise, When contrasted to the Tundra, their rainfall was much more significant. Therefore, consequently, the NPP in marshlands were much higher. |
