A9litre jug is full of water. i have three cups which can hold 7litres, 2litres and 4litres respectively. find a way to pour water from the jug between the cups so that i end up with exactly 3 litres in three of the vessels

Here's a solution in 8 pours. The list here has the form ...

from vessel ⇒ to vessel; (vessel contents for vessels 9, 7, 4, 2)

The starting state is (9, 0, 0, 0).

Steps 6 and 8 can be swapped, as the order in which vessels 9 and 4 are filled to the 3 level doesn't matter.

step-by-step explanation:

see if this :

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
