The correct answer is - 2. There's an increase in the number of snakes and insects, and the storks face increased competition for food.

The significant decrease in the number of eagles, because of the human activity, and of the rabbits, because of a virus, has been of great use for the populations of the snakes to increase, as well as the populations of the insects. That has happened because the snakes lost their predator, and the insects lost a competition for a food source, so their numbers rose.

On the other hand, because of the increase of the number of snakes, the storks had started to face increased competition, as both have the same food source, the frogs.

Adam can clean a room in 3 hours. If his sister Maria helps, they can clean it in 225 hours. How long will it take Maria to do the job alone?
2 2 = 12 Together time, 2 2 , needs to be converted to fraction 555
Adan:3,Maria:x,Total: 5 Clearlystatetimesforeachandtotal,usingxforMaria 12
1+1= 5 Usingreciprocals,addtheindividualtimesgivestotal 3 x 12
1

1(12x) + 1(12x) = 5(12x) 3 x 12
4x+12=5x −4x −4x 12=x It takes Maria 12 hours
Multiply each term by LCD of 12x
Reduce each fraction
Move variables to one side, subtracting 4x Our solution for x
