Document Summary
Which will further lead to inc. probability of mortality. * of global population with low iodine availability. Can dictate presence/absence of species in a region. Limiting nutrients: some nutrients are going to be found in such small amounts in the environment that they can actually regulate or limit population growth. There is going to be change in population size. Impacts of enrichment on richness (# of species present in an given area) and diversity (# of species and relative abundance of each species. ) There will be a paradox of enrichment. Addition of nutrients will increase productivity to a certain level but will impact richness and diversity. Nutrient cycle: it is a cycle between biotic and abiotic worlds.
