What are the different methods of ingestion of food in different animals |
| Answer» Ingestion: The intake of food is called ingestion. Method of ingestion, i.e. taking of food, varies from one animal to another.Different organism takes food in different ways.\tA humming bird sucks nectar of plants.\tHuman beings use their hands to put food into their mouth and swallow the food after chewing.\tInfants of human and many other animals feed upon their mother’s milk by sucking them.\tA snake swallows the animals they prey upon without chewing them.\tA frog captures prey with its sticky tongue.\tAn earthworm uses its muscular pharynx to swallow its food.\tSpiders weave sticky web in which small insects get stuck.\tSome aquatic animals filter tiny particles floating nearby and feed upon them.\tAmoeba, a unicellular animal, engulfs tiny particles of food by using pseudopodia. Amoeba surrounds the food by pseudopodia and then makes a food vacuole to engulf the food.\tIn multicellular organisms; like hydra there are numerous tentacles around their mouth. Hydra uses tentacles to surround its prey and kill them with its stinging cells. Then the food is pushed inside the body cavity. | |

Elements and atomic number |
| Answer» Element: \xa0An element is made up of 3 particles, protons, neutrons and electrons. In the centre of an element there is a nucleus which contains protons and neutrons. Around an element are shells, also known as orbits which contain the electrons in an element. Protons have a positive charge and electrons have a negative charge, although neutrons have no charge at all.Atomic number: \xa0The total number of protons in the nucleus of an atom gives us the atomic number of that atom. It is represented with the letter ‘Z.’ All the atoms of a particular element have the same number of protons, and hence the same atomic number. | |
