Two alien species compete for resources on a planet far far away. Their initial populations are 100 and 1000 and their specific growth rate is 0.02263/year and 0.02/year and their yield coefficient is 0.95 and 0.85 respectively. When the first species begins to consume more than 50% of the resources the other population will be inevitably be annihilated. How many years does it take for this to occur?
