North Carolina is the most ecologically unique state in the southeast because its borders contain sub-tropical, temperate, and boreal habitats. Although the state is at temperate latitudes, the Appalachian Mountains and the Gulf Stream influence climate and, hence, the vegetation (flora) and animals (fauna).
Chemoautotrophs can use inorganic energy sources such as hydrogen sulfide, elemental sulfur, ferrous iron, molecular hydrogen, and ammonia or organic sources to produce energy. Most chemoautotrophs are prokaryotic extremophiles , bacteria , or archaea that live in otherwise hostile environments (such as deep sea vents ) and are the primary ...
There are different ecological dimensions that can be mapped to create more complicated food webs, including: species composition (type of species), richness (number of species), biomass (the dry weight of plants and animals), productivity (rates of conversion of energy and nutrients into growth), and stability (food webs over time). A food web ...
Omnivores, which feed on both plants and animals, can be considered as being both primary and secondary consumers. Tertiary consumers, which are sometimes also known as apex predators, are hypercarnivorous or omnivorous animals usually at the top of food chains, capable of feeding on both secondary consumers and primary consumers. Tertiary ...
An autotroph is an organism that can convert abiotic sources of energy into energy stored in organic compounds, which can be used by other organisms. Autotrophs produce complex organic compounds (such as carbohydrates , fats , and proteins ) using carbon from simple substances such as carbon dioxide, [ 1 ] generally using energy from light or ...
