Distinguish between hetrotrophs and auto trophs |
|
Answer» \tAutotrophsHeterotrophsAutotrophs are organisms that prepare their own food.Heterotrophs depend upon other organisms for nutrition.These are known as the producers and include green plants, algae and a few photosynthetic bacteria.These are the consumers and include cows, buffaloes, tigers, horses, etc.These can be classified as photoautotrophs and chemoautotrophs.These can be classified as photoheterotrophs and chemoheterotrophs.The chloroplast helps in preparing food.They do not contain chloroplast so cannot prepare food.They obtain energy from inorganic sources by converting light energy into chemical energy.They obtain energy directly or indirectly from other organisms.Autotrophs can store light energy and chemical energy.Heterotrophs cannot store energy.They are placed at the primary level in the food chain.These are placed in secondary or tertiary level in the food chain.These can move from one place to another in search of food and shelter.They cannot move from their place.\t Heterotrops are the species whoch depends on other species for food and many other things. |

How does use of a fuse wire protect electrical appliance? |
|
Answer» A fuse is a circuit connection that will be destroyed by excessive current flow, creating an open circuit, to protect electrical appliances from receiving too high current. It is designed to be the weakest link in the circuit, which fall before the other components are damaged. The simplest fuses contain thin wire strips that melts when heated by excessive current flow. A fuse wire consists of low melting point and high resistivity and it is always connected in livewire. Cubic bunk itch fun xxxiiऐ It gets heated when excess current is drawn through it and melted due to its low resistance and low melting point. Hence the circuit get breakdown and save other appliances Fuse wire melts and breaks supply when current exceeds its limit |

why do silver,gold and platinum not corrode in moist air? |
|
Answer» Platinum and gold are some of the elements that are found on the bottom of the reactivity series. This means that the two elements do not easily react with other elements. These metals are part of the group of the noble metals that have the character of least reactivity among the metals.This decrease in reactivity is due to the high ionization energies.This is therefore why gold and platinum do not corrode in moist air as they would not react with the water or air. Good bye diksha Because they are chemically unreactive |
