Not exact matches

In this way they act as recyclers, ferrying nutrients that might otherwise be lost back up to the surface.

Its tall, gangly, inefficient architecture makes it an environmental laggard among plants, one that sucks up water and fertilizer while leaching out gobs of nutrients that run off in rainfall, polluting surface waters from the Midwest to the Gulf of Mexico.

In today's ocean, nutrients are brought up to the surface around Antarctica but then move north and eventually flow into the low latitudes, supporting the plankton and fish populations there, Moore said.

Whale poop is important because it transports nutrients from the deep ocean, up to the surface.

At dusk, many of these deep - water animals migrate up to the nutrient - abundant surface waters to feed, relying on the darkness to protect them from predators.

In addition, seamounts rising into the ocean create obstacles that shape ocean currents and direct deep, nutrient - rich waters up the sloping sides of seamounts to the surface.

Processed food is much easier to chew and digest and since chewing breaks up the food it means more surface area is available from which the gut can absorb nutrients, Organ said.

For example: 1) plants giving off net CO2 in hot conditions (r / t aborbing)-- see: http://www.climateark.org/articles/reader.asp?linkid=46488 2) plants dying out due to heat & drought & wild fires enhanced by GW (reducing or cutting short their uptake of CO2 & releasing CO2 in the process) 3) ocean methane clathrates melting, giving off methane 4) permafrost melting & giving off methane & CO2 5) ice & snow melting, uncovering dark surfaces that absorb more heat 6) the warming slowing the thermohaline ocean conveyor & its up - churning of nutrients — reducing marine plant life & that carbon sink.

Phytoplankton, which live close enough to the water's surface to perform photosynthesis — critical to maintaining oxygen in Earth's atmosphere — form the base of the marine food web.4 Although phytoplankton are microscopic, they can be seen from satellites when they grow in a concentrated area (bloom) on the ocean's surface.5 Zooplankton, which feed on phytoplankton, and bacterioplankton, which recycle nutrients in the water, make up the next levels of the web.4

These are needed by the phytoplankton to replace the nutrients that they use up in the surface water.

Your second comment: Yes, the cold water is finite, but there is an awful lot of it down there and our pumping rate of one million cubic meters per second is quite feeble, so it will last long enough for us to figure out some other way to cool the surface and bring up nutrients so we can feed ourselves.
