Image: NASA SEAWIFS Research shows global photosynthesis on the rise «Virtually all life on our planet
depends on photosynthesis,» said UC Merced Professor Elliott Campbell, who led the research.
You can get about 50 times the energy out of solar cells covering the same area as a bio-reactor tank that
depends on photosynthesis, so I don't think the idea that fertilizing bio-fuels with the CO2 from coal combustion makes sense.
A distinction is made between phytoplankton, which
depend on photosynthesis for their energy supply, and zooplankton, which feed on phytoplankton.
Not exact matches
And so, yeah, if we look at the
photosynthesis, we are using like 30 percent to 50 percent of it
depending on what numbers you look at.
Its discovery upended one of biology's core tenets: That all life essentially
depends on the energy of the sun, either by using sunlight for
photosynthesis or by munching photosynthesizing organisms.
«Although tiny, these organisms are a vital part of the Earth's life support system, providing half of the oxygen generated each year
on Earth by
photosynthesis and lying at the base of marine food chains
on which all other life in the ocean
depends.»
Over the years, her team has shown that it's responsible for 5 % of global
photosynthesis and
depends on an estimated 80,000 genes distributed among hundreds of strains to thrive in nutrient - poor waters ranging from the sea surface to 200 meters down.
Both corals and algae
depend on sunlight to drive
photosynthesis, and the study attributed the existence of many of the deep reef habitats to exceptionally clear water.
Within the context of artificial
photosynthesis, membranes are desired that facilitate the ion transport necessary to feed the electrochemical reactions while meeting various additional selectivity and permeability demands
depending on the CO2 reduction products.
You have of course solar energy, which we know today, but also through
photosynthesis all of the fossil fuels
depend on the power of the sun being trapped in these plants.
However, this in itself is not enough to define what level of warming is «dangerous,» especially since the projections of actual impacts for any level of warming are highly uncertain, and
depend on further factors such as how quickly these levels are reached (so how long ecosystems and society have had to respond), and what other changes are associated with them (eg: carbon dioxide concentration, since this affects plant
photosynthesis and water use efficiency, and ocean acidification).
Secular Animist: «I'd point out that humanity has always
depended on what you call a «low quality» energy source for all of our food — which is solar energy transformed into chemical energy by
photosynthesis.»
I'd point out that humanity has always
depended on what you call a «low quality» energy source for all of our food — which is solar energy transformed into chemical energy by
photosynthesis.
Human civilization has
depended on our ability to «gather» solar energy through
photosynthesis for millennia — this is called «agriculture» — and today's solar thermal and photovoltaic technologies make it VERY easy to gather solar energy for electricity, water and space heating, etc..
They are limited by
photosynthesis efficiency (which does not
depend on CO2 concentration).
Of course, we do know that the rate of
photosynthesis (the rate - limiting step in the growth of most plants)
depends on temperature.
