To help readers better understand harmful algal blooms, which organizational pattern has the author used?

Cause and effect pattern is used.

Explanation:

Climate change pressures will influence marine planktonic systems globally, and it is conceivable that harmful algal blooms may increase in frequency and severity.

These pressures will be manifest as alterations in temperature, stratification, light, ocean acidification, precipitation-induced nutrient inputs, and grazing, but absence of fundamental knowledge of the mechanisms driving harmful algal blooms frustrates most hope of forecasting their future prevalence.

There is expectation that harmful algal bloom (HAB) geographical domains should expand in some cases, as will seasonal windows of opportunity for harmful algal blooms at higher latitudes.

1.   in sonnet 18, the speaker wants to describe the beauty of his love, but can’t find the words to do so. the speaker says “then in mid-utterance the lay was lost” when he tries to think of the words to describe his love’s beauty.   through his defeat of finding words to describe his love, he shows his love for her.

2.   instead of describing how perfect his love is or comparing her to other beautiful things, he says she is average and there is nothing special about her.   at the last 2 lines of the poem, the volta changes the poem by saying that even though his love is average in beauty, his love for her is special and unique. so instead of praising her throughout the whole poem, he contrasts her average characteristics with his special love for her.

3.   the beloved asked the speaker to describe how he feels about her. she begins to describe what she feels but "drop the torch" and says that she can't do it because the words "hid in me out of reach." the the speaker says "nay, let the silence of my womanhood command my woman-love to thy belief" and that her silence will have to be the answer to his question.
