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。

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。

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。

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。

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。

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。

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。

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。

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。

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”。

Remember the arrows in a food web always point from food to feeder.

请记住，食物网中的箭头总是从食物指向喂食器。

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。

The phytoplankton form the basis of a food web which supports larger organisms such as krill, fish, seabirds and marine mammals.

浮游植物是含有叶绿素的类似植物的微生物。浮游植物构成了食物网的基础，食物网支持较大的生物，比如磷虾、鱼类、海鸟和海洋哺乳动物。

48. What will happen if the populations of top predators in a food web greatly decline?

48. 如果食物网中顶级捕食者的数量大幅减少，会发生什么情况？

It is just where they are going to find their place in that -- in the ecosystem and in the food web.

问题是他们要在生态系统和食物网中找到自己的位置。

This concept is known as a food web, illustrating the multiple feeding connections between different species in an ecosystem.

这个概念被称为食物网，说明了生态系统中不同物种之间的多种进食联系。

We really need to start at the bottom and build up a really strong base on which to build up this food web.

我们真的需要从底层开始，建立一个非常牢固的基础，在此基础上建立这个食物网。

Higher up the food web, there's just less biomass - the mass of all the organisms that occupy that level.

在食物网的更高层，生物量更少——占据该层的所有生物体的质量。
