Organisms that can capture energy from sunlight or chemicals and use that energy to produce food are called autotrophs, or primary producers. The process in which autotrophs capture light energy and use it to convert carbon dioxide and water into oxygen and sugars is called photosynthesis.rganisms that can capture energy from sunlight or chemicals and use that energy to produce food are called autotrophs, or primary producers.

What to Expect With Rituxan. How Rituxan is given. RituxanÂ® (rituximab) is given as an intravenous (IV) infusion once weekly for 4 weeks.
