2. The function of ecosystem is related to the flow of energy and the cycling of materials through the structural components of the ecosystem
3. The major functional unit of the ecosystem is the population
4. The ecosystem has historical aspects: the present is related to the past, and the future is related to the present
An ecosystem is joined by thousands of species, if a problem occurs causing a species to become extinct, it may not affect the proper functioning of the ecosystem initially, but as more and more species are removed, the ecosystem becomes dangerously weak over a period of time.

The driving force for sintering a compact consisting of spherical particles of radius R1 is ΔG1. If the particle size is reduced to R2 = 0.1 R1, the corresponding driving force ΔG2 = αΔG1, where α is
The relation among various mass transfer co-efficients (M.T.C) for ideal gases is given by (where, Kc & Km are M.T.C. for equimolar counter diffusion with concentration & mole fraction respectively as the driving force. and, Kp = M.T.C. for diffusion of a gas through a stagnant inert gas with pressure as driving force.)
A entrusted his car to B for plying it as a taxi. B employed C as a cleaner. B gave the taxi to C for taking a driving test and to obtain a driving licence. C while giving the driving test seriously injured D. D filed a case against A, the owner of the vehicle.
Which of the following is the driving force of an ecosystem?
S1:A force of exists between everybody in the universe.
P :Normally it is very small but when the one of the bodies is a planet, like earth, the force is considerable.
Q :It has been investigated by many scientists including Galileo and Newton.
R :Everything on or near the surface of the earth is attracted by the mass of earth.
S :This gravitational force depends on the mass of the bodies involved.
S6:The greater the mass, the greater is the earth's force of attraction on it. We can call this force of attraction gravity.
