Because earth has natural cycles it goes through with ecosystems, and when we get involved with trying to help one spectrum of the natural world (rabbits for example) we hurt another (wolves, by over feeding, increasing the population, then exhausting the population of rabbits over a time.)
Hope this helps u!! If u have any questions just message me & more than welcome to help u on Brainly.com :)
Which coefficients balance this equation? _CH4 + _O2 -> _CO2 + _H2O A. 1, 1, 1, 1 B. 1, 1, 2, 1 C. 1, 2, 1, 2 D. 2, 1, 2, 1
ICE Princess25 [194]
C. 1,2,1,2
1 CH4+ 2 O2= 1 CO2+ 2 H20.
when balancing, you need to make sure that each side has the same number of each atom. The reason for this is to abide by the law of conservation of mass; essentially you can't have more or less than you put in the equation.
When you put the coefficients of C. into the equation you have a total of 2 carbon atoms on each side, 4 hydrogen atoms, and 4 oxygen atoms.
Answer: Fertilizers and pesticides contribute to runoff that goes into the water, causing habitat degradation.
Explanation:
Fertilizers and pesticides are the chemical formulations which are added to the agricultural field so as to enhance the growth of the crops and raising their yield. The runoff is the water erosion. In runoff water from any source such as rainwater, water from the snow melt and water from the river stream flows over the surface of soil. It remains unabsorbed within the soil. Such water flows with an appropriate speed and mixes with the water reservoir.
Thus according to the given situation, the fertilizers and pesticides along with the water runoff will be added to the water reservoir. As a result of this the increase in abundance of chemicals in the water source can make the water habitat unfit for the survival of aquatic animals due to contamination.
