Question

Rank the biomes in terms of how much you expect plant growth to increase as a function of increased co2 in the atmosphere.

Answer 1

The following are the expected ranks of biomes  based on increased oxygen for plant growth and they are

1. Desert,

2. Grassland

3.  Temperate Forest

4. Tropical Rain Forest

The desert biome is formed owing to very limited annual rainfall and it covers approximately 20% of the Earth.  The Grassland is predominantly dominated by grasses while the temperature in the temperate forest is around 10 degree celcius. The plants and trees in this biomes develop special adaptations for their survival. However, the rain forest is characterized with all year round rain hence the biome is moist. The biome is known for vegetations with dense canopies.
