During the Carboniferous Earth's atmosphere was more abundant in oxygen, which in turn resulted in very large insects, and the reason for the abundance of oxygen were the proportionally high numbers of producers compared to consumers.
Explanation:
The Carboniferous is a period that often is portrayed as being warm, wet, with Earth being covered with thick forests. That is partially true though, as that only describes one part of this period. Other things that are specific for the Carboniferous are the higher levels of oxygen in the atmosphere, as well as the huge insects, centipedes, millipedes, and arachnids.
The unusually high levels of oxygen in the atmosphere were a result of the abundance of producers, from cyanobacteria to trees, but not enough consumers. That led to constant pumping out of oxygen into the atmosphere, as well as extraction of carbon dioxide. One effect of the abundance of oxygen has been that the insects and their relatives achieved greater sizes, as the higher amount of oxygen enabled their growth and reaching the maximum size for animals that have exoskeletons. Another effect was that the oxygen cooled off the global climate with time, so the warm and wet climate was replaced by a long and harsh ice age.
Thins that occurred during the Carboniferous were:
- amniote egg
- enormous organic deposits that later turned into coal
- collision of Laurasia to Gondwana
- collision of Siberia to Eastern Europe
