El plancton y las redes tróficas marinas
El plancton, a pesar de su diminuto tamaño, es crucial para el funcionamiento de las redes tróficas marinas, en las que no solo un organismo se come a otro, sino que, cuando lo hace, ayuda a que los nutrientes acumulados en la misma materia viva se liberen de nuevo y vuelvan a estar disponibles para las algas. El plancton está presente en aguas continentales y en todos los mares y océanos del planeta. Además, es el responsable de que haya vida en la Tierra y nos ha proporcionado (a escalas geológicas) una buena parte del oxígeno que respiramos. Solo en una pequeña cuchara de agua de mar ya podemos encontrar unos cincuenta millones de virus, cinco millones de bacterias, cientos de miles de pequeños flagelados unicelulares, miles de algas microscópicas, aproximadamente cinco ciliados o dinoflagelados heterótrofos y, con mucha suerte, algún pequeño crustáceo, como los copépodos. Este libro intenta dar una visión clara y amena sobre este conjunto de microorganismos y las diversas funciones que realiza en el mar.
