Creating a complex food web inside us.

这就在我们的体内创造了一个复杂的食物网。

Basically, they are part of the food web.

基本上，它们是食物网的一部分。

Phytoplankton serve as the base of ocean food webs.

浮游植物是海洋食物网的基础。

A network of interconnected food chains is called a food web.

食物链之间相互交错、互相影响，构成生物网。

But all this biodiversity makes these environments vital to regional food webs.

然而，正是这种生物多样性使得环境对区域食物网的稳定性发挥着至关重要的作用。

This could have irreversible global-scale impacts on marine life and food webs.

这可能会对全球范围的 海洋生物和食物网造成不可逆的影响。

So let's take the food web of a woodland environment as an example.

让我们以林地环境中的食物网为例。

Well, to figure it out, we have to look at the whole food web.

为了弄清楚，我们必须研究整个食物网。

We're talking about the loss of everything that depends on pollination in the food web.

我们谈论的是食物网中所有依赖授粉的生物的消失。

This means that when a food web is altered, it has different effects from different populations.

这意味着当食物网被改变时，不同的种群会产生不同的影响。

So altering one link in the food web has big consequences for the whole system.

因此，改变食物网中的一个环节会对整个系统产生重大影响。

Now, plants are producers, meaning they form the base of nearly all the food webs on Earth.

现在，植物是生产者，这意味着它们构成了地球上几乎所有食物网的基础。

These food relationships between the different members of the community are known as food chains or food webs.

生物群落里不同物种间的食物关系称为食物链或食物网。

Without them, we would have no flowering plants, which would harm the food web that supports important animals.

如果没有它们，我们就不会有开花的植物，这将会损害支持重要动物的食物网。

Nor is it obvious what impacts these changes might have on broader ecological communities, and on the food web.

而这些变化可能对更广泛生态社区和食物网络产生的影响也不明朗。

Experts say coral reefs create homes for millions of species encourage healthy marine food webs and protect coastlines.

专家说，珊瑚礁为数百万物种创造了家园，鼓励健康的海洋食物网，并保护海岸线。

So they likely play more of a stabilizing role in food web dynamics. They're not a top apex predator.

“所以，它们可能在食物网动态中发挥着更为稳定的作用。它们并不是顶端掠食者。

The impact of a predator down through the food web all the way to plants is called a trophic cascade.

捕食者沿食物链往下一路直达植物的影响被称为“营养级联”。

The more diverse our biomes are, the more security they have against species extinction and threats to their food webs.

我们的生物群落越多样化，它们就越能抵御物种灭绝和食物网受到的威胁。

This shift matters, Hammerschlag says, because tiger sharks are apex predators, and where they go influences the food web beneath them.

哈默施拉格表示，这种转变很重要，因为虎鲨是食物链顶端的掠食者，它们的去向会影响它们下面的食物网。
