Answer:

One major side effect of DDT was the extreme damage to bird populations. DDT caused the shells of bird eggs to become extremely thin, which made them prone to breaking from minor disturbances and failing to thrive due to temperature regulation issues. It also slowly poisoned animals, especially birds that fed on insects that were poisoned by DDT. A notable bird species that was affected by DDT is the bald eagle. At one point in the 1960s, bald eagles nearly went extinct due to various effects of DDT. The threat of one of the most recognizable animals in America going extinct led to lawmakers trying to ban DDT.

never [62]

Answer:

Herbicide essentially replaces sugar with itself during uptake by plants.

Explanation:

Noting that the pH is decreased around the plant cells indicate that there is an acidic environment that exists, It also indicates that the cell wall  had been perforated and the contents are being expelled or at the very least leaking.

The ability for the plant to break down and use sugar is vital for its survival. Most herbicides are in the form of glycophosphates and it moves along with the sugar in the plant that have been treated with herbicides through the transport vesicles, the xylem and phloem.

This causes an imbalance in the available sugars that are able to be taken up by the plant since much of it is replaced by the herbicide.
