To know if a reaction is well balanced between the reactants and the products, you have to calculate the number of atoms of each element on both sides of the reaction and to check if they are equal.
*For carbon, on both sides, there are 8 carbon atoms.
*For hydrogen, on both sides there are 20 hydrogen atoms.
*For oxygen, there are 20 oxygen atoms in the reagents and 26 in the products, so it is necessary to increase the number of oxygen in the reactants (without touching the others). For this we put 13 O2 in the reactants instead of 10, to have 26 oxygen atoms on each side.
One reason why a species may go extinct is due to environmental changes. For example, if a environment undergoes deforestation / wild fires it’s environment will no longer be grassy green and would not allow for an animal like the Japanese rat snake to use its green coloring to camouflage from predators
