calculate the amount of energy that will be available to big fish in the following food chain, if 10,000 j of energy is available to small algae from the sun:small algae zooplankton fish big fish
food chain= small algae—zooplankton—fish—big fishthe algae receive 10,000j of energy out of which it absorbs only 1% i.e. 100j. 10% of 100j i.e. 10j is transferred to zooplankton. fish receives 10% of this 10j= 1j. out of 1j energy available to the fish, 10% is transferred to the next trophic level i.e. big fish. 10% of 1j is 0.1j. hence, 0.1j of energy will be available to big fish if 10,000j of energy is available to small algae from the sun.
no. it is not true.

the sun is already a gigantic hydrogen bomb.
it converts about 620,000,000 tons of hydrogen into energy every second
adding another kilogram or two would make no difference.

as well, the sun's core is the only place where the nuclear reactionnis self sustaining. in the sun's atmosphere, the temperature (and pressure) are not high enough. i think the fish you are describing is "tropheus". they are a very pretty & aggressive smaller fish. small don't count your betta before they are hatched ;) ! getting the fish to breed is the easiest part, survival of the fry is more difficult.

expect 0 to 500 fry to survive! (they can lay up to about 600 eggs in a spawn). so you might get none, and if everything is perfect you might have 500 so better plan on how to house them. i would not expect anything close to 500 on your fish's and your first try, maybe 100 if you are lucky but there is always the possibly of more. experienced breeders often have surviving clutches of 400 or more!

as the sun gets older, it will continue to fuse hydrogen in its core, scientists estimate that there is enough hydrogen fuel to continue this process for another 4 billion years or so, then the fun starts….

once the majority of the sun’s hydrogen is turned into helium, it stops fusing hydrogen and loses its ability to combat gravity, the sun will begin to compress under its own weight. the higher pressures and temperatures at the sun’s core will cause helium to begin to fuse into carbon in a similar process to the hydrogen fusion, this too balances out the gravity and the sun will continue to shine, but the process of fusing helium gives off more energy than the fusing of hydrogen. this additional energy streaming out of the core radiates through the “envelope”, the layers outside the core. this very high energy into the envelope heats up the envelope causing the envelope expand greatly to hundreds of times its original size. 

the part that can be seen (the envelope) is much cooler than the young sun was and it is red in color, the sun has become a red giant star. 

even though the red envelope is cooler than the young sun it is still very hot, about 5000° fahrenheit! unfortunately, for any life on planets in the inner solar system, the red giant sun's envelope will expand to engulf all the way out past earth and mars. all the oceans will be evaporated away and in fact the earth's atmosphere will be blown into space. the engulfed planets will, obivously, be uninhabitable. sadly many fish have been killed while following the misinformation printed on the bottle of bottled bacteria. it can't make a tank instantly safe for fish. for some it has sped up the cycling process but it doesn't instantly cycle a tank.

if you choose to try again i would do a total tank clean out and start over. you are early enough in the cycling process to do this. if you choose to do a fish in cycle i will recommend you purchase an api master freshwater test kit. with it you can know exactly what is going on in this tank. it tests for ph (both high and low), ammonia, nitrites and nitrates. i will also recommend you get a bottle of seachem prime. it is first and foremost a water conditioner but goes one step farther and detoxed low levels of ammonia.

once you have these 2 things and have cleaned the tank out i will recommend you use your tap water with the proper dose of prime added to it to remove chlorine/chloramines. if the minerals hadn't been added back into the ro water you added, that too could have added to the death of your fish.

once all these things have been done get one fish. bettas are about the only fish i can recommend for a tank this size. once the fish is in there it will start producing ammonia. it will take a few days before you start seeing ammonia in the tank. don't ever let the ammonia get any higher than .5 even lower is better but with prime your fish should be fine at this level.

water changes as the ammonia starts rising is going to protect you new water pet. at some point you are going to start seeing nitrites. when that happens you don't want the total amount of ammonia plus nitrites to get above 1.0 keep them down with water changes. be sure to add prime with every water change. no matter what the test say never go longer than a week between water changes. with a tank this small things can go bad quickly so keep a close eye on the numbers. heat lost by the vessel and water= [150 x 4.2 x (30 - 5) j + 100 x 0.4 x (30-5)] j = (150 x 4.2 x 25 + 100 x 0.4 x 25) j = (15,750 + 1000) j= 16,750 j heat gained by ice to change into water at 0 °c = m x specific latent heat of fusion of ice = {m x 336} heat gained by water to come to final temperature (5 °c) = m x specific heat capacity of water x final temperature = (m x 4.2 x 5) = 21m if there is no loss of heat to the surroundings, according to the principle of calorimetry: heat gained by ice to melt and come to final temperature = heat lost by vessel and water or 336m + 21m= 16,750 or 357m = 16,750 or m = 16750/357 = 46.92 your cubic meter box contains about 1.2 kg of air. the specific heat of air is about 1 kilojoule per kilogram per degree centigrade.

so 1.2 kilojoules per degree centigrade. to get from 20c to 1000c you need 980 * 1.2 = 1176 kilojoules = 327 watt-hours. you can get 1440 watts from a us 15a hous… centripetal force:f=mv2rr is equal to l in this question.1. f = (100)(1602)/2500 = 1024 n2. f = (300)(802)/10000 = 192 n3. f = (400)(802)/2500 = 1024 n[readmore]4. f = (200)(1602)/5000 = 1024 n5. f = (800)(402)/10000 = 128 n6. f = (200)(1202)/5000 = 576 n1 = 3 = 4 > 6 > 2 > 5the order of forces acting on the satelites from the largest to the smallest is 1 = 3 = 4 > 6 > 2 > 5
