오염원으로부터의 거리에 따라 식물체내의 중금속 함량에 뚜렷한 차이가 나타나는 이유는? | , 1979; Berg and McClaugherty, 2003). 식물은 뿌리를 통해서 뿐만 아니라 대기로부터 중금속을 흡수한다. 따라서 오염원으로부터의 거리에 따라 식물체내의 중금속 함량에 뚜렷한 차이가 나타난다(Berg et al. | |
중금속이 자연환경 내에 널리 퍼져있는 이유는? | 최근 급속히 발전하는 산업 활동으로 인해 중금속은 자연 환경 내에 널리 퍼져있다(Laskowski and Berg, 1993). 중금속은 일반적으로 유기물의 분해에 중요한 역활을 하는 토양내 미생물을 포함한 생물군에 광범위하게 독성을 나타내는 것으로 알려져 있다(Zwolinski, 1994). | |
낙엽 분해의 과정은 생태계 내에서 무엇을 통해 안정성을 제공하는가? | 낙엽 분해의 과정은 생태계 내에서 필수 원소의 순환에 가장 중요한 과정으로 식물의 생장과 분해의 균형을 통해 안정성을 제공한다(Swift et al., 1979; Berg and McClaugherty, 2003). |
