WebThe many nested cycles of carbon associated with ocean productivity are revealed by the following definitions (Bender et al. 1987) (Figure 1). "Gross primary production" (GPP) ... WebClimate and the Carbon Cycle Through photosynthesis, phytoplankton consume carbon dioxide on a scale equivalent to forests and other land plants. Some of this carbon is carried to the deep ocean when phytoplankton die, and some is transferred to different layers of the ocean as phytoplankton are eaten by other creatures, which themselves reproduce, …

WebMay 20, 2024 · More importantly, decomposers make vital nutrients available to an ecosystem ’s primary producers —usually plants and algae. Decomposers break apart complex organic materials into more elementary substances: water and carbon dioxide, plus simple compounds containing nitrogen, phosphorus, and calcium. WebRecent projections of climatic change have focused a great deal of scientific and public attention on patterns of carbon (C) cycling as well as its controls, particularly the factors that determine whether an ecosystem is a net source or sink of atmospheric carbon dioxide (CO2). Net ecosystem production (NEP), a central concept in C-cycling research, has been … WebMar 25, 2024 · Harnessing the power of artificial intelligence, satellites and field observations, Duke researchers have produced new estimates of how much photosynthesis and primary production – key components in the global carbon cycle – are occurring in Earth’s oceans, and how these processes may be changing in response to a changing … the hyning estate
