What is eco system? |
|
Answer» An ecosystem is the combination of biotic components comprising living organism and abiotic components comprising physical factors like temperature, rainfall, wind, soil and minerals An\xa0ecosystem\xa0is a community of living organisms in conjunction with the non living components\xa0of their environment, interacting as a system.\xa0These biotic\xa0and abiotic components\xa0are linked together through nutrient cycles and energy flows.Energy enters the system through photosynthesis\xa0and is incorporated into plant tissue. By feeding on plants and on one-another, animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial biomass\xa0present. By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling\xa0by converting nutrients stored in dead biomass back to a form that can be readily used by plants and other microbes. The interrelation and interdependence of living organisms on each other for nutrition and other activities The interaction b/w living and non living things forms an ecosystem |

Explain use of Fleming right hand rule acc. to chapter? |
|
Answer» Direction of indused current Fleming\'s right-hand rule (for generators) shows the direction of induced current when a conductor moves in a magnetic field. It can be used to determine the direction of current in a generator\'s windings.When a conductor such as a wire attached to a circuit moves through a magnetic field, an electric current is induced in the wire due to Faraday\'s law of induction. The current in the wire can have two possible directions. Fleming\'s right-hand rule gives which direction the current flows. |
