When it comes to diatoms (that live in the ocean,new research suggests thatphotosynthesis(光合作用)is not the only strategy for accumulating carbon.Instead,thesesingle-celled are also building biomass by feeding directly on organic carbon in the ocean.These new findings could lead researchers to reduce their estimate of how much carbondioxide diatoms pull out of the air via photosynthesis,which in turn,could take a much closerlook at the understanding of the global carbon cycle,which is especially relevant given thechanging climate.The new findings were published in Science Advances on July 17,2024.The team showed that the diatom Cylindrotheca closterium,which is found in oceansaround the world,regularly performs a mix of both photosynthesis and direct eating of carbonfrom organic sources such as plankton(浮游生物).In more than 70%of the water samplesthe researchers analyzed from oceans around the world,the team found signs of simultaneousphotosynthesis and direct organic carbon consumption from Cylindrotheca closterium.Theteam also showed that this diatom species can grow much faster when consuming organic如carbon in addition to photosynthesis.Furthermore,the new research hinted at the possibilitythat specific species of bacteria are feeding organic carbon directly to a large percentage of創these diatoms living all across the global ocean.This work is based on a genome-scalemetabolic modeling approach that the team used to reveal the metabolism of the diatom长Cylindrotheca closterium.The team's new metabolic modeling data support recent lab experiments suggesting thatBsome diatoms may rely on strategies other than photosynthesis to intake the carbon they needto survive,thrive and build biomass.部The UC San Diego led team is in the process of expanding the scope of the project todetermine how widespread this non-photosynthetic activity is among other diatom species.新28.What's new according to the research?A.The way of the diatom's carbon accumulation.款B.The impact of climate on diverse sea plants.C.The procedure of exploring carbon.D.The system of building biomass.29.What do the new findings make researchers more focus on?A.The causes of climate change.B.The grasp of the carbon cycle.C.The bad effect of photosynthesis on diatoms.D.A rough estimate of the amount of carbon dioxide.30.What do we know from paragraph 3?A.A large number of diatoms may feed on bacteria.B.The diatom lives on plankton.C.Water samples are key factors for the research.D.Diatom species grow faster with sufficient sunlight.【高三英语第5页（共10页）】5/10CX
