An example of data being processed may be a unique identifier stored in a cookie. TSS includes settleable solids, and is the direct measurement of the total solids present in a water body. Orcas have sleek black-and-white skin which helps them camouflage when hunting prey in both deep water depths and near shorelines where light reflects off the water surface differently.The black coloring on an orcas back extends down its sides into a saddle area just behind its dorsal fin while its belly remains white; this coloration is thought help orcas blend in with both shadowed areas created by their own bodies when swimming at depth , as well making it difficult for prey species looking upwards from below to distinguish between an approaching orcas dark back against the bright sky above . Some abiotic factors that affect the killer whale are water, air and soil. In lakes the amount of sunlight that reaches underwater plants depends on the clearness of the water or water clarity. What emotions and thoughts does it evoke in you? There is a strong relationship between water clarity and orca survival. The Secchi disc is lowered into the water until it disappears, then pulled up until it can just barely be seen. With this knowledge, you will determine how abiotic factors like water temperature, water clarity, carbon dioxide, and oxygen affect the kelp since they form the base of food pyramids as producers. The most direct way is ingesting contaminated water, which can lead to health problems and even death. Resident orcas live in matriarchal pods and eat fish such as salmon. Surface water clarity is widely recorded using satellite-based remote sensing. Note the following about Water Clarity and how it affects aquatic life: Water clarity refers to the measure of how deep light can penetrate through water. They're belly's are white, so if a predator is looking up the whale will blend into its surroundings. As a result, the entire food chain is affected, with fewer fish surviving to adulthood.
