This one too. Sorry if i am pestering................
(a) The terminals are always connected to the Y-Plates of the oscilloscope

(b) If we apply a voltage on the Y-Plates (the spot will move up and down ) (Imagine this as the y and x-axis like in geometry, the y-axis being the path of movement of the Y-plates ...)

(c) The time base is the other name for the X - Plates. It causes the spot to move sideways. In this case, since the spot is moving up and down only, it is presumably off

Explain why there is an increased efficiency
in supplying green plants as human food and
that there is a relative inefficiency, in terms of
energy loss, in feeding crop plants to animals ??

Mai(M4!)
okay i will tell u the ans but not 100% sure

see, when humans consume green plants as there food they are acting as primary consumer while
when animals are fed on the crop plants then we consume the animals then we are secondary consumer
so it is more efficient to be at primary consumer level as we will have more energy gained due to less number of trophic levels and when animals consume the plants first they lose alot of energy in respiration, movement and excretion even fighting diseases so eating plants directly gives more energy so more efficient due to less energy loss by animals because as the trophic level increases the energy available decreases .

Hope this was the right answer :D (y)(y);)
