WebEstimating and interpreting ecosystem metabolism remains an important challenge in stream ecology. Here, we propose a novel approach to model, estimate, and predict multiseasonal patterns of stream metabolism (gross primary production [GPP] and ecosystem respiration [ER]) at the reach scale leveraging on increasingly available … Webtrophic levels. There are a number of factors that regulate and limit primary production in aquatic ecosystems, being the most important solar radiation and nutrients. Particularly, solar radiation—quantity and quality—strongly affects the photosynthetic process. Solar radiation attenuates with depth (as a function of particulate and dissolved

Marine primary production - Wikipedia
WebJan 18, 2024 · Algae, phytoplankton, and rooted macrophytes represent the base of many aquatic food webs and are known as primary producers. Through photosynthesis, these organisms convert sunlight energy into chemical energy (i.e., carbon) that in turn fuels the growth of animals such as macroinvertebrates and fish. This project uses high frequency … WebThe open ocean and tropical rain forests contribute the most to Earth’s net primary production because a. both have high rates of net primary production. b. both cover huge surface areas of Earth. c. nutrients cycle fastest in these two ecosystems. d. the ocean covers a huge surface area and the tropical rain forest has a high rate of production. WebGiven the world’s expanding human population, it is important to evaluate the net primary production of different ecosystems that can provide food.
