| | Ecology |
 | | Ecology is the branch of biological sciences dealing with the interactions between organisms and their environment (chemical and physical factors). |
 | | Ecology makes use of Physics because all biotic processes has to do with the transference of energy, as from producers, which take advantage of light energy for producing complex organic compounds, to bacteria, which obtain chemical energy by the disintegration of the molecular structures of other organisms. |
 | | Mathematics is crucial for Ecology, for example for the calculus, statistics, projections and extrapolations when Ecologists deal with specific information about the number and distribution of species, the evaluation of biomass, population growth, extension of communities and biodiversity, and to quantify the environmental pressures at a given biome. |
