Answer:the environmental factor that influences the amount of sunlight that reaches the underwater plants and animals are abiotic factors. Aquatic biomes are influenced by a series of abiotic factors. However, these factors differ since water has different physical and chemical properties than does air. Even if the water in a pond or other body of water is perfectly clear (there are no suspended particles), water, on its own, absorbs light. As one descends into a deep body of water, there will eventually be a depth which the sunlight cannot reach. While there are some abiotic and biotic factors in a terrestrial ecosystem that might obscure light (such as fog, dust, or insect swarms), usually these are not permanent features of the environment.
The chemical make-up of a rock refers to its composition. Your answer is correct. This is because geologists determine the amount of occurring inorganic solids and chemical composition in minerals the make-up a particular kind of rock. The variety of arrangements of chemical elements in a rock determine its basic or complex composition.
