Pupils did not volunteer ideas that suggested that they appreciated the complexity of causes of rainforest destruction.

Answer 1

Pupils 是主语
did not volunteer 是谓语
ideas 是宾语 后面是定语从句
that 是关系代词 引导定从 并作定从中的主语
suggested是定从中的谓语 后面是定从中的宾语从句
that 是连接词 引导宾语从句 不作句子成分 可省略
they是宾语从句中的主语
appreciated是宾语从句中的 谓语
the complexity of causes of rainforest destruction是宾语从句中的宾语

本句 关键 是 能看出 定语从句中 包含了宾语从句 .
学生们不会主动地说出 表明他们认识到了造成热带雨林毁坏的原因的复杂性 的想法。

Answer 2

Pupils did not volunteer ideas （that suggested that）（ they appreciated the complexity of causes of rainforest destruction.)
等价于Pupils did not volunteer ideas（+A定语从句）(+B宾语从句)后面的that可以省略，
令（ they appreciated the complexity of causes of rainforest destruction.)=B
则有Pupils did not volunteer ideas （that suggested B.）这样能看懂了？
