The global biomass broken down by kingdom and into taxonomic groups for animals. [1] The estimates for bacteria and archaea have been updated to 30 billion tonnes C combined since this figure was made. [20] Most of the global biomass is found on land, with only 5 to 10 billion tonnes C found in the oceans. [24]
A bio-based material is a material intentionally made, either wholly or partially, from substances derived from living (or once-living) organisms, [1] such as plants, animals, enzymes, and microorganisms, including bacteria, fungi and yeast. [2] [3]
Biomass is a term used in several contexts: in the context of ecology it means living organisms, [1] and in the context of bioenergy it means matter from recently living (but now dead) organisms. In the latter context, there are variations in how biomass is defined, e.g., only from plants, [ 2 ] from plants and algae, [ 3 ] from plants and ...
As a consequence of the quantitative magnitude of microbial life (calculated as 5.0 × 10 30 cells, [11] [12]) microbes, by virtue of their biomass alone, constitute a significant carbon sink. [13] Microbial interactions with their environment have industrial application such as wastewater treatment and bioremediation [ 14 ] [ 15 ]
[4] [5] Plate tectonics are needed for life over a long time span, and carbon-based life is important in the plate tectonics process. [6] Iron- and sulfur-based Anoxygenic photosynthesis life forms that lived from 3.80 to 3.85 billion years ago on Earth produced an abundance of black shale deposits. These shale deposits increase heat flow and ...
Access to the previously invisible world opened the eyes and the minds of the researchers of the seventeenth century. Antonie van Leeuwenhoek investigated diverse bacteria of various shapes, fungi, and protozoa, which he called animalcules, mainly from water, mud, and dental plaque samples, and discovered biofilms as a first indication of microorganisms interacting within complex communities.
Types of biomass commonly used for bioenergy include wood, food crops such as corn, energy crops and waste from forests, yards, or farms. [3] Bioenergy can help with climate change mitigation but in some cases the required biomass production can increase greenhouse gas emissions or lead to local biodiversity loss. The environmental impacts of ...
Bacteria. In the microbial food web, bacteria play a crucial role in breaking down organic materials and recycling nutrients. They transform DOC into bacterial biomass so that protists and other higher trophic levels can consume it. Additionally, bacteria take part in the nitrogen and carbon cycles, among other biogeochemical cycles. [4] Algae
