Explanation:
In the given question, the graph and table have not been provided either they are found anywhere, therefore, the question has been answered on previous knowledge.
The species of Earth can adapt to their environment but adaptation in organisms can take a long time that is thousands to Lakh of years. But the rise in temperature is observed constantly past 200 years.
The species living in the tropics, equator and Poles are already adjusted for their thermal limit. If the average temperature of the planet will increase by 1°C then the number of individuals in the population will decrease. As the number of individuals will decrease, the number of population of species will decrease.
Due to this declination, the number of species can become extinct and therefore the process of increase in temperature and number of species that become extinct can be co-related.
