A chromatid has something to do with chromosome
The alkali metals in group l of the periodic table all have a single electron in the outermost shell. These metals form covalent bonds with for example the halogens, which have 7 electrons in their outer shell.
When the alkali metal halide, such as KCl is dissolved in water, it dissociates into ions. The K atom loses the single electron, and therefore has a positive charge. In turn, the chloride atom gains the electron and becomes the negatively charged chloride ion.
The main reason causing average global temperature rise is increase in amount of green house gases like Carbodioxide, and since deforestation reduces a vast number of plants, so there is lack of plants absorbing CO2 causing this whole thing.
So, according to this the Correct choice is B
If there weren't secondary consumers, then the primary consumers population would increase. Also, plant life would be threatened, which would cause increased difficulty for primary consumers to survive after they overpopulate.So the population increases in producer (and probably producer diversity) and decreases in secondary, tertiary and higher order consumer populations.
