This creation of oxygen
by photosynthesis changed our planet's atmosphere and made our lives possible.
Not exact matches
Climate
change has generally proved beneficial to trees because warmer temperatures stimulate
photosynthesis and extend the growing season, and both rural and urban trees grew faster
by up to 17 % after 1960.
By comparing almost 400 grass species our research has led to unexpected discoveries that will now
change the way we think about C4
photosynthesis.»
«
Photosynthesis was such a powerful invention that it
changed Earth's atmosphere
by producing oxygen, allowing diverse and complex life forms — algae, plants, and animals — to evolve.»
In climate
change scenarios simulated
by the model GOTILWA + — within the Consolider - Ingenio project Montes and the research project Med - Forestream — , net primary productivity of Spanish forests (how much carbon dioxide plants take in during
photosynthesis minus how much carbon dioxide they release during respiration) will decrease from the second half of this century.
For example, carbon dioxide, the dominant form of carbon in the atmosphere and associated with climate
change, is used
by plants to generate energy via
photosynthesis.
Production may be directly affected
by changes in crop
photosynthesis and water use due to rising CO2 and
changes in regional temperature patterns.
By combining biocompatible light - capturing nanowire arrays with select bacterial populations, a potentially game -
changing new artificial
photosynthesis system offers a win / win situation for the environment: solar - powered green chemistry using sequestered carbon dioxide.
In the Amazon, Liu et al found that the
change resulted from a * decrease in
photosynthesis * (as revealed
by changes in chlorophyll fluorescence).
The observed
change in acidity due to human emissions of CO2 are ALREADY a threat to much of the life in the sea, and most of the oxygen produced
by photosynthesis comes from sea plants.
However, the carbon you exhale into the atmosphere was recently removed from the atmosphere
by plants during
photosynthesis, yielding a net
change of zero.
Choice 5: Does the fact that life on this planet has survived a billion years of climate
change caused
by orbital mechanics, asteroids, the evolution of
photosynthesis, plate tectonics, the variable star we call the sun, chaos, plagues, and possibly supernovae.
Furthermore in contrast to researchers arguing rising atmospheric CO2 will inhibit calcification, increased
photosynthesis not only increases calcification, paradoxically the process of calcification produces CO2 and drops pH to levels lower than predicted
by climate
change models.
A potentially game -
changing breakthrough in artificial
photosynthesis has been achieved with the development of a system that can capture carbon dioxide emissions before they are vented into the atmosphere and then, powered
by solar energy, convert that carbon dioxide into valuable chemical products, including biodegradable plastics, pharmaceutical drugs and even liquid fuels.
where Ea represents annual carbon emissions from anthropogenic sources (fossil fuel use and land use
change), En represents the carbon emissions from all natural sources (the oceans, soil respiration, volcanos etc.) and Un represent the uptake of carbon
by all natural carbon sinks (oceans,
photosynthesis, etc.).
Increased CO2 will aid
photosynthesis by phytoplankton and so
change ocean chemistry.
Is there any likelihood a bloom of plankton (from a freshwater pulse, or fallout of a dust cloud full of minerals, for example) would
change the temperature of the surface water (
change the reflectivity, I suppose, or
change how much is absorbed
by making more complicated molecules for
photosynthesis)-- sufficient to make the water mass density
change, affecting whether it sinks or not?
