The effect of this problem is that negative particles and positive particles contract to each other caused by electrical force.
One consequence of Newton's third law of motion is that all actions have equal and opposite reactions. <em>(C)</em>
In fact, that's pretty much what the law itself says in so many words.
Weeds are very important agronomically because they reduce the yield of crops in three ways: by competing with the crop for water, light and nutrients, by interfering with crop harvest, and by contaminating harvested products with weed seeds and toxins. Weeds can reduce yield up to 50% and are responsible for millions of dollars in crop losses each year.
It’s biotic factor would be competition as Competition can be defined as an interaction between organisms or species, in which the fitness of one is lowered by the presence of another.
