On land, the biomass of animals (zoomass) is many times less than the biomass of plants (phytomass). In the World Ocean, the opposite is true: the zoomass is about 20 times more than the phytomass. How can this be explained?
Since the rate of reproduction and growth is higher, the lifespan is longer in plants. In addition, due to photosynthesis, plants accumulate biomass (producers) more intensively than animals (consumers). In terrestrial biogeocenoses, the total mass of products is higher for producers, i.e. in plants.
In the oceans, the total mass of phytoplankton is less than that of zooplankton and their consumers (fish, molluscs). Planktonic phytoorganisms grow faster, but they die at the same rate, therefore, they cannot increase the biomass of a large amount.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
