  2. Ecosystem respiration - Wikipedia

    en.wikipedia.org/wiki/Ecosystem_respiration

    Ecosystem respiration is the sum of all respiration occurring by the living organisms in a specific ecosystem. [1] The two main processes that contribute to ecosystem respiration are photosynthesis and cellular respiration. Photosynthesis uses carbon-dioxide and water, in the presence of sunlight to produce glucose and oxygen whereas cellular ...

  3. Crassulacean acid metabolism - Wikipedia

    en.wikipedia.org/wiki/Crassulacean_acid_metabolism

    However, the reason for CAM in aquatic plants is not due to a lack of available water, but a limited supply of CO 2. [15] CO 2 is limited due to slow diffusion in water, 10000x slower than in air. The problem is especially acute under acid pH, where the only inorganic carbon species present is CO 2 , with no available bicarbonate or carbonate ...

  4. Soil respiration - Wikipedia

    en.wikipedia.org/wiki/Soil_respiration

    The respiration of plant structures releases not only CO 2 but also other nutrients in those structures, such as nitrogen. Soil respiration is also associated with positive feedback with global climate change. Positive feedback is when a change in a system produces response in the same direction of the change.

  5. Net ecosystem production - Wikipedia

    en.wikipedia.org/wiki/Net_ecosystem_production

    Net ecosystem production (NEP) in ecology, limnology, and oceanography, is the difference between gross primary production (GPP) and net ecosystem respiration. [1] Net ecosystem production represents all the carbon produced by plants in water through photosynthesis that does not get respired by animals, other heterotrophs, or the plants themselves.

  6. CO2 fertilization effect - Wikipedia

    en.wikipedia.org/wiki/CO2_fertilization_effect

    Through photosynthesis, plants use CO 2 from the atmosphere, water from the ground, and energy from the sun to create sugars used for growth and fuel. [22] While using these sugars as fuel releases carbon back into the atmosphere (photorespiration), growth stores carbon in the physical structures of the plant (i.e. leaves, wood, or non-woody stems). [23]

  7. Aerobic organism - Wikipedia

    en.wikipedia.org/wiki/Aerobic_organism

    3: Facultative anaerobes can grow with or without oxygen because they can metabolise energy aerobically or anaerobically. They gather mostly at the top because aerobic respiration generates more ATP than either fermentation or anaerobic respiration. 4: Microaerophiles need oxygen because they cannot ferment or respire anaerobically. However ...

    The plants require a cool climate at high altitude but due to increasing global temperatures, species are moving to higher ground with drooping saxifrage now found 50 metres from the top of Ben ...

  9. Effects of climate change on biomes - Wikipedia

    en.wikipedia.org/wiki/Effects_of_climate_change...

    Furthermore, climate change may disrupt the ecology among interacting species, via changes on behaviour and phenology, or via climate niche mismatch. [9] The disruption of species-species associations is a potential consequence of climate-driven movements of each individual species in opposite directions.
