Chlorophyll is the green light trapping pigment essential as an electron donor in photosynthesis. A colloidal state represent properties that are intermediate between those of an ordinary suspension and those of a true solution. Colorimetric determination is the process by which a specific compound is analyzed on the basis of its ability to react with another chemical and change color. The color is then measured on an instrument using a controlled light source which can distinguish small differences in color. A compound is a pure substance that can be broken down by chemical means into two or more simpler substances.
Condensation is the process of water vapor in the air turning into liquid water.
Water drops on the outside of a cold glass of water are condensed water. Condensation is the opposite process of evaporation. Top D Decomposers include organisms such as bacteria and fungi that break down plant and animal remains into forms once again usable by producers. Denitrification is the process by which nitrates are converted to ammonia and molecular nitrogen as by denitrifying bacteria. Disinfection is the process by which chemicals are added to water to reduce bacterial contamination.
