A hunter-gatherer is a human living in a society in which most or all food is obtained by foraging (collecting wild plants and pursuing wild animals). Hunter-gatherers who did not change have been displaced or conquered by farming or pastoralist groups in most parts of the world. A major reason for this focus has been the widely held belief that knowledge of hunter-gatherer societies could open a window into understanding early human cultures. After all, it is argued, for the vast stretch of human history, people lived by foraging for wild plants and animals.

Dionysius Exiguus was known to use nulla alongside Roman numerals in 525. Because Roman Numerals System was developed for mostly knowing the price of goods, and to trade. So, there was no need for a symbol to represent zero. Instead of the number zero, the word “nulla” (the Latin word meaning "none") was used by the Romans.

Plants are called producers. This is because they produce their own food! They do this by using light energy from the Sun, carbon dioxide from the air and water from the soil to produce food - in the form of glucouse/sugar. The process is called photosynthesis. Green plants are called photoautotrophs. Green plants are called by this name because they use sunlight to produce their own food. Also, green plants are breath in carbon dioxide and emit out oxygen into the atmosphere.

Scurvy happens when there is a lack of vitamin C, or ascorbic acid. The deficiency leads to symptoms of weakness, anemia, gum disease, and skin problems. This is because vitamin C is needed for making collagen, an important component in connective tissues. Scurvy can be prevented by a diet that includes vitamin C-rich foods such as amla, bell peppers (sweet peppers), blackcurrants, broccoli, chili peppers, guava, kiwifruit, and parsley. Other sources rich in vitamin C are fruits such as lemons, limes, oranges, papaya, and strawberries.

Milk, meat and eggs are the food products we get from animals. Animal products are rich in vitamins and proteins. Though pulses, whole wheat, corn, and so on, also give us proteins, proteins derived from animals are considered to be better than those from plant sources. There are 4 (four) basic food energy sources: fats, proteins, carbohydrates and alchol. Humans are omnivorous animals that can consume both plant and animal products. The main sources of our food are Plants and Animals. Plants are the sources of food ingredients like grains, cereals, vegetables and fruits. Animals are the another source which provide us with milk, meat products and eggs.

The Jallianwala Bagh massacre, also known as the Amritsar massacre, took place on 13 April 1919, when Acting Brigadier-General Reginald Dyer ordered troops of the British Indian Army to fire their rifles into a crowd of unarmed Indian civilians in Jallianwala Bagh, Amritsar, Punjab, killing at least 379 people and injuring over 1,000 other people. The Amritsar massacre fundamentally changed how the Indians saw the Raj (the era of British rule, which ran from 1757 to 1947). It led Mahatma Gandhi, who during the first world war had forsaken his pacifism to help recruit soldiers to preserve the empire, to see British rule as satanic.

There are many food items we get from animals. For example: fish, eggs, meat, milk, butter, and other milk products. Thus, food that we get from animals is called food of animal source. Other foods come from plants, including rice, wheat, fruit, beans and vegetables. We also eat food that animals make. For example, chickens produce eggs and cows give milk.
