旁白：现在在生物课上听一节关于这个话题的讲座。

Narrator: Now listen to part of a lecture on this topic in a Biology class.

教授：好的，蚂蚁中有一个很好的例子。

Professor: OK, so here's a good example of this among ants.

蚂蚁居住在一些大的巢穴中。一类特殊的蚂蚁，

Ants live together in these large nests, and certain ants,

如觅食蚂蚁，有一份特殊的工作要做。

the forager ants, have a particular job to do.

They go out each day to look for food items,

树叶，种子，水果，诸如此类的东西。

然后这些蚂蚁把它们带回到蚁巢，这样所有的蚂蚁都可以吃。

And then these ants bring them back to the nest so all the other ants can eat them.

觅食蚂蚁不只是把它们能找到的任何食物带回来，

Now the forager ants don't just bring back whatever they may happen to find,

成年蚂蚁通常喜欢吃富含糖分的食物，因为它们需要能量来在巢中进行其他活动。

adult ants normally like to eat things that are rich in sugar because they need energy to carry on other activities in the nest.

所以，当蚁群主要是由成年蚂蚁组成的时候，

So, at a time when the colony is composed mostly of adult ants,

觅食蚂蚁寻找水果和其他含糖的食物。

the forager ants look for pieces of fruit and other sugar-rich items.

它们把这些带回蚁巢，让成年蚂蚁吃东西来获得所需的能量。

They bring these back to the nest for the adult ants to eat to get the energy they need.

但是一年中有一段小蚂蚁出生的时间，

But there is a time of the year when baby ants are born,

这些小蚂蚁需要一种不同的食物。

now the baby ants need a different kind of food.

它们需要食物来帮助它们成长为成年蚂蚁，

They need food that will help them grow into adults,

所以它们的食物需要富含蛋白质。

so their food needs to be rich in protein.

所以现在觅食蚂蚁做了一些不同的事情。

So now the forager ants do something different.

它们开始收集更多富含蛋白质的食物，

They start to gather more food items that are rich in protein,

like certain types of leaves or mushrooms.

通过这种方式，年轻的蚂蚁获得了帮助它们生长所需的蛋白质。

This way, the young ants get the protein they need to help them grow.

Communal Nutrition &nbsp;
Some kinds of social insects live in large groups or colonies in which different members of the colony have different tasks to keep the colony running smoothly. Some members of the colony are responsible for providing appropriate food for the entire colony. These insects typically practice communal nutrition. They gather different kinds of food and bring it to the nest to be shared by all members of the colony. They instinctively adjust and regulate the food they provide to meet the particular nutritional needs of the different members of the colony at any given time.&nbsp;

 Using the example of ants, explain the concept of communal nutrition.
