Primary and secondary production of mixed forest?

Primary products are those that are produced by autotrophs (plants) for a certain unit of time. It can be gross, if it is all the substance that was formed in the process of photosynthesis and pure – what remains after plant nutrition (goes to the growth of deciduous and coniferous trees and grass), to the life processes of consumers (herbivorous heterotrophs and predators) and decomposers ( bacteria and fungi). And secondary production is an increase in the mass of consumers for a certain time. The mixed forest is home to a wide variety of plants and many animals.
