Explanation / Answer
BY 2090, the terrestrial flora population is decreasing.
Carbon level in soil in 2090 is 2089GT. These results are when net deforestation rate is 1 GT. If we change the deforestation rate, corresponding carbon levels will also change.
Carbon level increase leads to global warming. It also effects other biogeochemical cycles like, hydrogen cycle, oxygen cycle etc. Rate of photosynthesis is greatly affected by this. This will lead to overall change in flora of any area. Plant species may either become extinct due to increase in the temperature, or they wil develop certain resistance in their bodies to combat this overall climate change. This resistance effect may be phenotypic and genotypic.
