structures of ecoysystems |
| Answer» Ecosystem is defined as the structural, functional and self-sustaining unit of biosphere, which consists of biotic and abiotic components.Biotic components of ecosystem: Producers are the green plants which can prepare food themselves. Green plants can prepare their own food due to the presence of chlorophyll. For e.g.: Sunflower, mango plant.Consumers are the heterotrophs that depend on green plants directly or indirectly for their food. For e.g.: Dog, Lion etc.Decomposers are the saprophytic organisms that feed on dead and decaying organic matters and decompose them into simpler forms. For eg: Bacteria, Fungi etcAbiotic components are the non-living chemical and physical factors in the environment that affect ecosystems. Abiotic components play a crucial role in all of biology. Abiotic factors are broadly grouped into physiographic, edaphic and climactic factors and atmospheric gases. | |

What is appendix in our digestive system and its function |
| Answer» The appendix or vermiform appendix is a muscular structure attached to the large intestine in the human body. The diameter of the appendix usually ranges from 7 to 8 mm and its length ranges between 2 and 20 cm, with an average length of 9 cm. The appendix is usually located at the lower right side of the abdomen. The appendix is made of inner mucosa layer just like the rest of the digestive tract and is also known as the vermix or the cecal appendix.The function of the vermiform appendix in the human body is not fully established yet. Scientists believe that it is a vestigial remnant, that is, it was once useful to humans in the digestion of food, but as we have evolved, it has lost its function and become redundant. Some research studies show that the appendix is rich in lymphoid cells, which help the body fight infections, and hence it could have a role in the body’s immune functions. | |

What is the the persentage of water in human bones ? |
| Answer» On average, the body of an adult human being contains 60% water. Most of the water in the human body is contained inside our cells.The total amount of water in our body is found in three main locations: within our cells (two-thirds of the water), in the space between our cells and in our blood (one-third of the water).The body of a newborn is composed of more water (75%) than that of an elderly person (50%).All our vital organs contain different amounts of water: the brain, the lungs, the heart, the liver and the kidneys contain a large quantity of water – between 65 to 85% depending on the organ , while bones contain less water (but still 31%). | |
