...study reports that many types of plants tend to grow more quickly in a carbon dioxide-rich environment, but that these plants contain fewer nutrients than plants grown in a normal environment. Consequently, these nutrient deficient plants take longer to decompose, which in turn leaves fewer nutrients available in the ground for new plants in the spring...
...attempt to determine the effects of atmospheric carbon dioxide levels on the ecosystem, Bazzaz and Fajer also examined the reactions of various insect populations to such nutrient deficient plants...
They found that butterfly larvae, which were fed leaves from nutrient deficient plants, had a higher rate of mortality and a slower rate of growth. Since insects constitute an important link in the food chain, lower populations of insects may have a huge impact upon animals and humans, they said...
Couched in a halo of nutrient cells, an egg smaller than the dot on an i drifts slowly down a Fallopian tube, one of a pair of narrow passages that lead from a woman's ovaries to her womb. Like a beacon guiding ships at night, the egg sends forth a calling signal. A convoy of sperm -- the remnants of an armada that was once a couple of hundred million strong -- sails into view, their long tails thrashing vigorously. Lured by the chemical signal, several hundred of the most energetic swimmers close in on the egg, their narrow tips unleashing...
...listed on product packages. This phase will also address the tricks associated with serving size. Until the federal agency jumped into the fray, private physicians and nutritionists had been fighting a lonely rearguard action in this realm of superslim slivers and oversize wedges. A manufacturer wishing to boost the nutrient value of a cereal, for example, simply bases the label on an oversize portion. If low calories are the object, the portion becomes minuscule. Take, for example, Entenmann's fat-free Chocolate Loaf Cake, which boasts a scant 70 calories per 1-oz. serving. No one with a sweet tooth...
