Non-vascular plants can also play important roles in other biomes such as deserts, tundra and alpine regions. They have been shown to contribute to soil stabilization, nitrogen fixation, carbon assimilation etc. These are all crucial components in an ecosystem in which non-vascular plants play a pivotal role.

A coal mine in Wyoming, United States. Coal, produced over millions of years, is a finite and non-renewable resource on a human time scale.. A non-renewable resource (also called a finite resource) is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption. [1]
[29] [30] Although the uranium ore used to fuel nuclear fission plants is a non-renewable resource, enough exists to provide a supply for hundreds to thousands of years. [ 31 ] [ 32 ] However, uranium resources that can be accessed in an economically feasible manner, at the present state, are limited and uranium production could hardly keep up ...
Chloroplasts (green discs) and accumulated starch granules in cells of Bryum capillare. Botanically, mosses are non-vascular plants in the land plant division Bryophyta. They are usually small (a few centimeters tall) herbaceous (non-woody) plants that absorb water and nutrients mainly through their leaves and harvest carbon dioxide and sunlight to create food by photosynthesis.
Some non-renewable sources of energy, such as nuclear power, [contradictory] generate almost no emissions, while some renewable energy sources can be very carbon-intensive, such as the burning of biomass if it is not offset by planting new plants. [12] Renewable energy is also distinct from sustainable energy, a more abstract concept that seeks ...
Researchers have also suggested using biomass as a carbon source for fuel production. Adding hydrogen to the biomass would reduce its carbon to produce fuel. This method has the advantage of using plant matter to cheaply capture carbon dioxide. The plants also add some chemical energy to the fuel from biological molecules.
Vascular plants (from Latin vasculum 'duct'), also called tracheophytes (UK: / ˈ t r æ k iː ə ˌ f aɪ t s /, [5] US: / ˈ t r eɪ k iː ə ˌ f aɪ t s /) [6] or collectively tracheophyta (/ ˌ t r eɪ k iː ˈ ɒ f ɪ t ə /; [7] [8] [9] from Ancient Greek τραχεῖα ἀρτηρία (trakheîa artēría) 'windpipe' and φυτά (phutá) 'plants'), [9] are plants that have lignified ...
NUGs may be privately held facilities, corporations, cooperatives such as rural solar or wind energy producers, and non-energy industrial concerns capable of feeding excess energy into the system. [3] An independent water and power producer (IWPP) is similar to an IPP, but with a unified process to also output usable treated water. [4]
