A food pyramid's tip is the smallest part, so the fats and sweets in the top of the Food Pyramid should comprise the smallest percentage of the diet. The foods at the top of the food pyramid should be eaten sparingly because they provide calories, but not much in the way of nutrition.
[7] 100×10 15 grams of carbon/year fixed by photosynthetic organisms, which is equivalent to 4×10 18 kJ/yr = 4×10 21 J/yr of free energy. Cellular respiration is the reverse reaction, wherein energy of plants is taken in and carbon dioxide and water are given off. The carbon dioxide and water produced can be recycled back into plants.
A pyramid of energy or pyramid of productivity shows the production or turnover (the rate at which energy or mass is transferred from one trophic level to the next) of biomass at each trophic level. Instead of showing a single snapshot in time, productivity pyramids show the flow of energy through the food chain .

The Food Pyramid (Hebrew: פירמידת המזון) from Israel's Ministry of Health is divided into six levels. At the wide base is water; followed by starches, including pasta, bread, corn and yams; then fruits and vegetables; then meat, fish, eggs and dairy; then fats and oils; and finally sugary foods at the small apex.
Primary nutritional groups are groups of organisms, divided in relation to the nutrition mode according to the sources of energy and carbon, needed for living, growth and reproduction. The sources of energy can be light or chemical compounds; the sources of carbon can be of organic or inorganic origin. [1]
Carbon emissions from transport account for 11% of the total carbon emissions of food, of which the transportation from producer to consumer accounts for 4%. [45] However, "food miles" are a misleading measure; in many cases food imported from the other side of the world may have a lower carbon footprint than a locally produced equivalent, due ...
More than a decade after Agriculture Department officials ditched the pyramid, few Americans have heard of MyPlate, a dinner plate-shaped logo that emphasizes fruits and vegetables.
