Herbivores and carnivores are examples of organisms that obtain carbon and electrons or hydrogen from living organic matter. Chemoorganotrophs are organisms which use the chemical energy in organic compounds as their energy source and obtain electrons or hydrogen from the organic compounds, including sugars (i.e. glucose), fats and proteins.

[51] [52] Proteins are vital parts of living organisms, as they are the main components of the physiological metabolic pathways of cells. The proteome is the entire set of proteins, [53] produced or modified by an organism or system. This varies with time and distinct requirements, or stresses, that a cell or organism undergoes.
[12] 2000–2009 saw approximately 17,000 species described per year. [12] The total number of undescribed organisms is unknown, but marine microbial species alone could number 20,000,000. [ 12 ] For this reason, the number of quantified species will always lag behind the number of described species, and species contained in these lists tend to ...
A primary law of population ecology is the Malthusian growth model [50] which states, "a population will grow (or decline) exponentially as long as the environment experienced by all individuals in the population remains constant."
Population ecology – study of dynamics of species populations and how these populations interact with the environment; Urban ecology – study of the relationships between living organisms with each other and their urban environment. Biogeography – study of the distribution of species spatially and temporally.
Population: Groups of organisms of the same species: Guild: Interspecific groups of organisms carrying the same ecological function (i.e. herbivores). Community (or biocoenosis) Guilds from all biological domains, and their interactions in a specific location. Ecosystem: Groups of organisms in conjunction with the physical environment. Biome
Microbiology (from Ancient Greek μῑκρος (mīkros) 'small' βίος (bíos) 'life' and -λογία () 'study of') is the scientific study of microorganisms, those being of unicellular (single-celled), multicellular (consisting of complex cells), or acellular (lacking cells).
A bear with a salmon. Interspecific interactions such as predation are a key aspect of community ecology.. In ecology, a community is a group or association of populations of two or more different species occupying the same geographical area at the same time, also known as a biocoenosis, biotic community, biological community, ecological community, or life assemblage.
