Introduction: Specific gravity or relative density is the ratio of the density of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water. Temperature and pressure must be specified for both the sample and the reference. The following formula is used- Specific gravity= density of sample/density of same volume of water. Specific gravity is commonly used as a simple means of obtaining information about the concentration of solutions

Unit 4 Ecosystems Background Introduction The abundance of a species and species diversity affect how natural resources are processed within an ecosystem. This pattern of processing contributes to functional and compositional characteristics of an ecosystem. But many ecosystems around the world are currently experiencing significant changes in species composition‚ abundance‚ and diversity due to the influence of human activity. These changes have‚ more often than not‚ led to a reduction in species
