Answer:
Cyanobacteria were photosynthetic and slowly changed the earth's atmosphere from CO2 rich to O2 rich. Photosynthetic cyanobacteria evolved by 3.5 billion years ago and greatly modified earth's atmosphere.
The right answer is climate change.
Amphibians do not have the possibility of producing heat. Their activity depends on the environmental temperature and its fluctuations. For example, an average temperature increase of 1 ° C is likely to increase the metabolic expenditure of ectotherms by at least 10 to 30%. Global warming has or will have a significant impact on populations and their ability to adapt according to the evolutionary history of species.
