I Review According to the biogeochemical cycle shown below, which of the following processos can move carbon from the abiotic reservoir to the biotic reservoir? Geological processes contribute to the abicceservous. For example, erosion may transfermiers from rock to sol Abiotic reservers are non living components of an ecosystem where chemicals accumulate. For example, carbon cumulates in the atmosphere as Col while wygen accumulates when it is dissolved in seawater Preducers incorporate inorganic chemicals from an abiotic reservoir Into organic compounds For example, a plant uses Co, from the air to make glucose via photosynthesis When consumers feed, they incorporate the chemicals of food into their own bodies. For example, a deer munching on grass incorporates some of the nutrients from that grass into sing tissue. BIOTIC COMPONENTS Decomposers break down the organic molecules in wastes and dead organism. The sample compounds they release become part of the abiotic reservoir.

notch is a receptor protein displayed on the surface of certain cells in developing fruit fly embryos. notchs ligand is a membrane-bound protein called delta that is displayed on the surface of adjacent cells. when notch is activated by its ligand, the intracellular tail of the notch protein becomes separated from the rest of the protein. this allows the intracellular tail to move to the cells nucleus and alter the expression of specific genes.T/F
