- some と others の後ろにingが来ている理由がわからないです
以下の英文があります。意味はわかるのですが、文法構造が一部わからないところがあります。 Billions of liters of liquid waste pollutants are dumped into the world’s waterways every day. The pollutants take a range of forms, form raw sewage to invisible toxic chemicals. Many of them are organic, some breaking down into harmless elements, but others thriving so well that they multiply rapidly and consume all of the oxygen in the water, killing the fish. 3パラグラフ目に、 「some breaking down into harmless elements」「others thriving so well that they multiply・・・」とありますが、someとothersの後ろにing形がなぜ来ているのかがわかりません。 お教え頂けると幸いです。 よろしくお願いします。

microorganisms play a major role in degrading organic chemicals, often using these chemicals as a carbon source in their metabolism. この場合、often using は何にかかっているのですか？また、動名詞？分詞、どちらでしょうか？ 後もう一つ、 Phytoremediation is the use of plants and plant processes to remove, degrade, or render harmless hazardous materials present in the soil or groundwater. Phytoremediation＝植物で汚染土壌を改善する技術 soil＝土壌 degrade＝分解する render＝かえる、返還する plants and plant processes がANDで結ばれているのですが、PLANTには名詞しか意味がありません。PLANT PROCESSESで一つの名詞と思いつくしか方法はありませんか？PLANTが主語だと考え、PROCESSESが動詞だと考えてしまいました。

European imperialist and colonialist powers had apprehensions about Jihad before 1914; Clemenceau had predicted it in 1912, if war broke out between the Great Powers. In August 1914, Charles Lutaud, the Governor of Algeria expected a rebellion and on 5 November, tried to forestall the Ottoman call to arms, by presenting the Ottomans as German puppets. The French were assisted by Royal Navy code breaking, to anticipate landings from German U-boats and negate the intriguing of the Central Powers. French prestige after the Moroccan Crises, reduced the likelihood of attempts to overthrow the colonial regime and German prisoners of war, were used as forced labour in Morocco and Algeria, to display French military prowess. Most of the French regular troops were sent to France in 1914 and replaced by Territorial troops in Morocco but on the frontier of Algeria and Libya, Senussi operations against the Italian army led the French to allow the garrisons of Ghadames and Ghat to retreat into Algeria and then be rearmed to re-capture Ghadames in January 1915, as part of the French policy of drawing Italy into the war.
