2. Ecological efficiency - Wikipedia

   en.wikipedia.org/wiki/Ecological_efficiency

   Ecological efficiency is a combination of several related efficiencies that describe resource utilization and the extent to which resources are converted into biomass. [ 1 ] Exploitation efficiency is the amount of food ingested divided by the amount of prey production ( I n / P n − 1 {\displaystyle I_{n}/P_{n-1}} )

3. Biological carbon fixation - Wikipedia

   en.wikipedia.org/wiki/Biological_carbon_fixation

   Cyanobacteria such as these carry out photosynthesis.Their emergence foreshadowed the evolution of many photosynthetic plants and oxygenated Earth's atmosphere.. Biological carbon fixation, or сarbon assimilation, is the process by which living organisms convert inorganic carbon (particularly carbon dioxide, CO 2) to organic compounds.

4. Ecological stoichiometry - Wikipedia

   en.wikipedia.org/wiki/Ecological_stoichiometry

   The difference, or mismatch, between the elemental demands of organisms and the elemental composition of resources leads to an elemental imbalance. Consider termites, which have a tissue carbon:nitrogen ratio (C:N) of about 5 yet consume wood with a C:N ratio of 300–1000. Ecological stoichiometry primarily asks:

5. Transient climate response to cumulative carbon emissions

   en.wikipedia.org/wiki/Transient_climate_response...

   [6] [14] The IPCC Sixth Assessment Report, which is the most thorough estimate as of 2021, [3] suggests a likely TCRE of 1.4 °C–2.2 °C per Tt C (or 1000 Pg C), a narrowing of the 0.8° to 2.5 °C per Tt C range estimated by the IPCC in 2013.

6. Fractionation of carbon isotopes in oxygenic photosynthesis

   en.wikipedia.org/wiki/Fractionation_of_carbon...

   δ 13 C sample is the delta-value of the organism for 13 C composition; δ 13 C atm is the delta-value of atmospheric CO 2, which is = -7.8‰ the discrimination due to diffusion a = 4.4‰ the carboxylation discrimination b = 30‰ c a is the partial pressure of CO 2 in the external atmosphere, and; c i is the partial pressure of CO 2 in the ...

7. Water-use efficiency - Wikipedia

   en.wikipedia.org/wiki/Water-use_efficiency

   Water-use efficiency is also a much studied trait in Plant ecology, where it has been used already in the early 20th century to study the ecological requirements of Herbaceous plants [12] or forest trees, [13] and is still used today, for example related to a drought-induced limitation of tree growth [14]
