4. Exceeding the necessary quantity of food. Biblical example: One of the sins of Sodom was "fullness of bread." [14] 5. Taking food with too much eagerness, even when eating the proper amount, and even if the food is not luxurious. Biblical example: Esau selling his birthright for ordinary food of bread and pottage of lentils. His punishment ...
The term photosynthesis is derived from the Greek phōs (φῶς, gleam) and sýnthesis (σύνθεσις, arranging together), [97] [98] [99] while another word that he designated was photosyntax, from sýntaxis (σύνταξις, configuration). Over time, the term photosynthesis came into common usage. Later discovery of anoxygenic ...
Cereal grain is a staple food that provides more food energy worldwide than any other type of crop. [19] Corn (maize), wheat, and rice account for 87% of all grain production worldwide. [20] [21] [22] Just over half of the world's crops are used to feed humans (55 percent), with 36 percent grown as animal feed and 9 percent for biofuels. [23]
Metabolism (/ m ə ˈ t æ b ə l ɪ z ə m /, from Greek: μεταβολή metabolē, "change") is the set of life-sustaining chemical reactions in organisms.The three main functions of metabolism are: the conversion of the energy in food to energy available to run cellular processes; the conversion of food to building blocks of proteins, lipids, nucleic acids, and some carbohydrates; and the ...
One strategy to get the needed nutrition is used by ruminants (e.g., cows). They chew the cud in order to process their food a second time to extract more nutrients. [26] [20] Another strategy (e.g., used by horses) is to have a very long colon to aid in digestion and absorption. [17] Both of these strategies add substantial bulk to the animal.
Amandines de Provence, poster by Leonetto Cappiello, 1900, which shows a woman eating almond cookies. Eating (also known as consuming) is the ingestion of food.In biology, this is typically done to provide a heterotrophic organism with energy and nutrients and to allow for growth.
For an overall efficiency of 20%, one watt of mechanical power is equivalent to 18 kJ/h (4.3 kcal/h). For example, a manufacturer of rowing equipment shows calories released from "burning" food as four times the actual mechanical work, plus 1,300 kJ (300 kcal) per hour, [16] which amounts to about 20% efficiency at 250 watts of mechanical output.
Water plays an important role in the world economy. Approximately 70% of the fresh water used by humans goes to agriculture. [26] Fishing in salt and fresh water bodies has been, and continues to be, a major source of food for many parts of the world, providing 6.5% of global protein. [27]
