only work well for the water bodies in the regions in which they were developed‚ and may give anomalous results in other types of water body. Biotic Indices The basis of any aquatic eco-system is water and the quality of the ecosystem may be determined by the quality of the water. Biotic indices can give an indication of the quality of the water. Biotic Indices‚ which are based on the presence or absence of particular indicator groups or species at the sampling point‚ are best suited for waters

Interaction Between Teenagers And Their Parents. In my opinion‚ there is not enough interaction between teenagers and their parents these days. I think it is true because of career of their parent‚ modern technology‚ and distance between them. The first reason is the career of their parent. The parents always hope their children were life in the best condition and were taken care in the best services. So they try to earn more money in order to pay for the fee of education of their children

What Shapes an Ecosystem? Ecosystems are made up of: * Biotic factors- all living parts of an ecosystem (plants‚ animals‚ bacteria) * Abiotic factors- all nonliving (but natural) parts of an ecosystem (soil‚ wind‚ water) These factors together (biotic and abiotic) determine which types of organisms can live in that particular ecosystem. A habitat- the place where an organism lives- includes both biotic and abiotic factors A niche includes both the habitat of an organism and its unique

A.Tenebrosa has a few abiotic factors that make them adapt to their situation and influence where they live and their distribution. Desiccation is the most important abiotic factor to consider because if they dry out and lose water they can die. Because A.Tenebrosa do not have a hard shell they find it much harder to store water‚ so they adapt themselves in a different way. Instead of storing water in their shell‚ the A.Tenebrosa fold their tentacles inside of their mouth and swallows the water to

of the individual than others‚ but all of them are hereditary. The geneticist is interested not only in the traits of man but in those of all other organisms as well. The study of inheritance depends on the differences as well as the similarities between parents and offspring over several generations. Heredity is very complex‚ and a geneticist cannot possibly analyze all the traits of an organism at once. Instead‚ he studies only a few traits at a time. Many other traits are present. As the geneticists

Mini Ecosystems Essay Ecology is the scientific study of all the interrelationships between organisms and their environment. An ecosystem is a biological community and all the non-living factors that affect it. Previously‚ in ---- biology class we created our own mini ecosystem terrariums. Lots of changes go on in ecosystems‚ and we got to record them. A terrarium is a self- contained terrestrial ecosystem that includes several species of plant‚ and sometimes animals too. What we had planned

Observing Ecosystems Ecosystems-The sums of all the organisms living within its boundaries and all the abiotic factors with which they interact. Chemical Elements such as carbon and Nitrogen are cycled among abiotic and biotic components of the ecosystem. Photosynthetic organisms assimilate these elements in inorganic form from the air‚ soil‚ and water and incorporate them into their biomass‚ some of which is consumed by animals. Both energy and matter are transformed in ecosystems throught
