Bacteria of species a and species b are kept in a single environment, where they are fed two nutrients. each day the environment is supplied with 10,540 units of the first nutrient and 19,510 units of the second nutrient. each bacterium of species a requires 2 units of the first nutrient and 3 units of the second, and each bacterium of species b requires 1 unit of the first nutrient and 4 units of the second. what populations of each species can coexist in the environment so that all the nutrients are consumed each day?
