生物基礎の(2)について質問です。 アは④が細菌だから間違えであってますか? またウとエはなぜダメなのか教えて欲しいです🙇 回答よろしくお願いします☀️ 返信は昼過ぎ位になります。すみません!

基本例題18 自然浄化 図は, 汚水が河川に流入したときにみら れる水中に含まれる物質の濃度の変化と生 物相の変化を示したものである。 (1) 図中の①~③ に当てはまる物質を,次 のa~c から選べ。 a. NH4+ b. 汚濁物質 c. 酸素 (2) 次のア~エの文のうち,正しいものを 1つ選べ。 濃度 個体数 汚水流入 4 上流 ア. ⑤は細菌で, ④ は清水性動物である。 イ. ①の一時的な減少は, 有機物の分解 で消費されたためである。 ウ.図中の▲の藻類の増加は,捕食者の 減少によるものである。 図中の△より下流での藻類の減少は、水の透明度の低下によるものである。 (3) 図のように生物などの働きによって汚濁物質が減少していく作用を何というか。 A 基本問題 105 考え方 (12) 汚水には, 有機物が多く含まれている。 その有機物を分解する細菌が増 殖すると酸素が消費される。 有機物は分解されるとNHを生じる。 NH』は,栄養塩類 として生産者に吸収され, アミノ酸などをつくる材料になる。 栄養塩類が増加すると, 生 産者である藻類が増殖するため酸素が増加する。 栄養塩類が減少すると藻類も減少する。 藻類 下流 解答 Ⅰ (1)①c ②a 3b (2) 1 (3) 自然浄化

共通テストのリーディングの問題で時系列的な問題があるのですが、何回やっても正解できません、 誰か教えて欲しいです。

B You found the following message on a personal blog written by an exchange student at your school. Save Our Park! Wednesday, April 21, 2021 Vera Sherman First, thank you for visiting my blog. Today I'm writing about something very close to my heart. I hope everyone in town has had a chance to spend some time at Kaneko Park. It is a lovely place, and it's easy to walk to from our school. As it is springtime, the park is currently full of blooming trees, singing birds, and people enjoying the outdoors. Some creative students even built little squirrel houses for the animals to live in. Unfortunately, however, we need to do more to help clean up our wonderful local park. One month ago, I was taking pictures of the flowers near the pond. When I looked at the pictures at home, I noticed some garbage in the background. I spoke to Mr. Tanaka, the city official who is in charge of the park. He told me that sometimes students eat fast food and leave packaging on the ground. He said that in the past he had asked students to clean up after themselves but very few students had actually done as he asked. Because students were a big part of the problem, I felt I should take some responsibility in trying to sort out this problem. I put up flyers explaining the situation and asking for students to help after school. A small group came out, but we were not well prepared. We didn't have enough trash bags, and we did not have a clear plan for cleaning up. I went back to Mr. Tanaka, and he promised me that next time we went to the park, the city would provide trash bags and maps of locations to clean. Now we are ready to make a difference. Maybe it doesn't seem fun to spend your time picking up trash, but please consider helping. We will be meeting outside the front gate of the park at 10 a.m. this Saturday. Please try to arrive by 10 a.m. as we will be starting the litter pick straight away. Let's all help clean up our beautiful park!
