At every trophic level a large amount of energy is lost in form of heat for maintaining metabolic activities and lost as heat. The amount of heat lost is generally 90 percent and the amount of energy retained is available from the previous trophic level to the next. The decline in energy level leads to :
i Lesser number of organisms in each trophic level.
ii Limited number of trophic level in food chains

- Greenhouse effect is the process by which radiations from the sun are absorbed by the greenhouse gases and not reflected back into space. This insulates the surface of the earth and prevents it from freezing.
- Acid Rain as the name suggests can be said to be the precipitation of acid in the form of rain in the simplest manner. When atmospheric pollutants like oxides of nitrogen and sulphur react with rainwater and come down with the rain, then this results in Acid Rain.
- Global warming is a gradual increase in the earth's temperature generally due to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.

The story 'Ranga's Marriage' is set in a village Hosahalli, which was in the erstwhile Mysore state. In those days, there were very few people in Hosahalli who knew English. Like today, even during those days, English occupied a very prominent place in the hearts and the minds of people. The village accountant mustered enough courage to send his son, Ranga, to Bengaluru for higher studies. When Ranga returned home, it became almost a festive occassion for the entire village. People had a lot of respect for Ranga because he knew English, which was a very precious commodity, but very few people in the village knew English. Even a simple word in English like 'change' was not heard of. When Rama Rao's son uses this word, even the narrator could not understand. He had to ask Ranga the meaning of the word. The author, in his narration, shows that he has a positive attitude towards English, but he also asserts that learning a foreign’ language or .knowing it need not affect our tradition and culture. This is evident by the emphasis on Ranga wearing the sacred thread and doing 'namaskars' to the elders.

Bohr’s Model of Atom
- According to Neil’s Bohr the electrons could revolve around the nucleus in only certain orbits known as discrete orbits of electrons, each orbit having different radii.
- When an electron is revolving in a particular orbit around the nucleus the electron does not radiate energy.
- Bohr’s model of an atom can be described as follows:-
- An atom is made up of three sub-atomic particles – protons, electrons, neutrons.
- The protons and neutrons are located in a small nucleus in the centre of the atom.
- The electrons revolve around the nucleus rapidly in fixed circular paths called energy levels or shells.
- There is limit in the number of electrons that each shell can hold. It is given by the formula 2n2, where n = orbit number or energy level index.
- Each energy level is associated with a fixed amount of energy.
- There is no change in the energy of the electrons as long as they keep revolving in the same energy level, and the atom remains stable.

In Δ ABC, B is at right angle.
Given, AB=24cm
BC=7cm
using Pythagoras theorem
AB2+BC2=AC2
⇒(24)2+(7)2=AC2
⇒AC=(242)+(7)2=576+49=625
⇒AC=25CM
sin A=BC/AC
= 7/25
