7·In other words, organic matter gets broken down and added into the soil more quickly in these gaps than in the surrounding forest.
换句话说，这些空地上的有机物分解并进入土壤的速度比周围森林中的更快。
8·The green iceberg did not contain large amounts of particles from these organisms, but the ice had accumulated dissolved organic matter from the seawater.

9·A third sources, the warming-enhanced decay of organic matter in forests and soils, especially in the middle and higher latitudes, is now being recognized as potentially significant.
第三个来源，特别是在中纬度和高纬度地区，森林和土壤中因气候变暖而加剧的有机物腐烂，现在被认为具有潜在的重大意义。
10·Most rainforest soils are thin and poor because they lack minerals and because the heat and heavy rainfall destroy most organic matter in the soils within four years of it reaching the forest floor.
大多数雨林土壤都很贫瘠，因为它们缺乏矿物质，而且高温和强降雨会在到达森林地面后的4年内破坏土壤中的大部分有机物。

2·It's very low in organic matter. And also the soil here, um, is very high in salt, being so close to the sea.
你可以看一下这篇土地，含沙量非常高，有机质含量非常低，而且盐分很高，和海水的含盐量差不多。
3·In nature, a bubble's lifetime depends on the level of dissolved organic matter and nanoparticles, without which small bubbles rapidly shrink and disappear.
在自然界中，一个气泡的寿命依赖于其所含可溶性有机质和纳米粒子的量，没有这些物质，气泡将迅速地缩减并消失。
