Note AMAZING ECOSYSTEM Author Rachel E. Oronia om eh Sunlight, soil, waves, temperature, nutrients, & salinity Are abiotic factors affecting organisms' survival in estuarine ecology Sunlight helps them grow, it aids plants' photosynthesis It secures animal growth and plants' food-malding process Nutrients and minerals from soil keep plants healthy Organisma keep up with temperature changes though oceans are wavy Salinity in estuaries is also a great need For organisms to survive and feed. EX 22 BIOTIC ABIOTIC What is it What are the biotic and abiotic components in estuaries? An estuary is a place where the freshwater from the river mixes with the salt-water from the sea. Biotic factors are the living components in an ecosystem. These include all the plants, animals, and microorganisms found in estuaries such as mangrove trees, migratory birds, and small fishes. Abiotic factors, on the other hand, are non-living components in the ecosystem. These are the factors that affect organisms in estuaries. These include waves, salinity, temperature, amount of sunlight, and type of soil. Biotic and Abiotic Factors in an Estuary Figure 2 Oana Abiotic factors -Sanity © Waves refer to the movement of the surface of the water. These are strong forces that organisms must earn to live with. An example of these organisms is the kelp, a kind of algae, which has root-like structures hat attach themselves to rocks to keep it from being carried away by the waves.​
