WebApr 13, 2024 · Abstract. The surface of intertidal estuarine sediments is typically covered with a photosynthetic biofilm. A large fraction of the carbon that is fixed is in the form of exopolymeric substances (EPS), providing the biofilm matrix. The consumption of organic carbon within the sediment column by heterotrophs bacteria is stratified according to the … WebOct 26, 2024 · Reactivity is the ability of matter to combine chemically with other substances. For example, iron is highly reactive with oxygen. When it combines with oxygen, it forms the reddish powder called rust (see Figure below). Rust is not iron but an entirely different substance that consists of both iron and oxygen.
