hello, es biju domājis, ka tu par planktonu gan zini, ja reiz it kā interesējies par tēmu.

visu drīkst. vienkārši pie tā ieinteresētības un pārliecinātības līmeņa, ar kādu tu raksti par lietām, biju domājis, ka esi nedaudz tēmā.

esmu daudz tēmā, naivi un intereses pēc gribēju, lai "speciālists" izskaidro saviem vārdiem.

un es biju gaidījis vairāk šādu atbildi:
Plankton are microscopic organisms that represent the base of the ocean food chain. More important for us, plankton function as part of a biological pump. As atmospheric CO2 is absorbed by the ocean, the phytoplankton use the CO2 and sunlight to photosynthesize. In the process, they produce oxygen and help to remove about one-third of the atmospheric CO2. The CO2 is absorbed into the phytoplankton shells, and ultimately sinks to the bottom of the sea as the plankton die off. The planet's health depends on regular plankton "blooms," in which enormous aggregations of plankton spread for miles over the world's oceans. The NASA satellite image here is a fragment of a plankton bloom off the New Zealand coast. Scientists are trying to understand the complex physical, chemical and biological mechanisms that trigger the plankton blooms. Dr. Mahadevan and her colleagues recently discovered a critical trigger: ocean eddies provide the necessary turbulence to rotate the warm surface water to the depths where temperatures are colder. In this discussion, Dr. Mahadevan explains the role of the phytoplankton in the absorption of CO2 and how ocean eddies cause the necessary circulation of the phytoplankton from surface to deep ocean.
