The world produces about 3.9 billion tons of food every year. of that amount, approximately 2.6 billion tons is consumed each year. the rest is wasted. what percentage of food is wasted every year? choose the closest answer.
1. 30%
2.33.33%
3. 60%
4.66.66%

2)  33.33%

Explanation:

Given :

Food produced each year = 3.9 billion

Food consumed each year = 2.6 billion

Food waster every year = Food produced each year -Food consumed each year = 3.9 billion- 2.6 billion = 1.3 billion

Percentage of food wasted each year =

Putting in the values we get:

Percentage of food wasted each year =

Thus the correct option is 33.33%.

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."    

phaneritic textures in which phaner means visible so phaneritic textures are standard of impertinent volcanic rocks. these rocks crystallized gradually under the surface of earth. when the magma cools deliberately then the ores have chance to develop and produce long crystals.
