food chain科普介绍 A food chain shows how plants and animals get their energy.
食物链显示了动植物是如何获取能量的。
Facts about Food Chains will inform [inˈfɔːm] you about living things that play a role as producers [prəˈdjuːsə] , consumers [kənˈsjuːmə] , and decomposers [ˌdiːkəmˈpəuzə] .
关于食物链的事实会告诉你生物作为生产者、消费者和分解者所扮演的角色。
Energy is needed by living things to grow and healthy.
生物成长和健康需要能量。
That is why they transfer their energy through the food chain.
这就是它们通过食物链传递能量的原因。
Besides, they are related [riˈleitid] and eat to each other such as grass (producer), zebra (primary consumer), and lion (secondary consumer).
此外，它们之间还相关，如草(生产者)、斑马(初级消费者)、狮子(次级消费者)。
Here are ten facts about food chains.
1、Facts about Food Chains 1: Producers
Plants make their own food by using energy of sunlight, carbon [ˈkɑːbən] dioxide [daiˈɔksaid] , and water.
植物利用阳光、二氧化碳和水的能量来生产自己的食物。
The process of it is called photosynthesis [ˌfəutəˈsinθisis].
这个过程叫做光合作用。
That is why they called as producers.
这就是为什么他们叫我生产者。
2、Facts about Food Chains 2: Consumers
Animals cannot make their own food such as plants, but they eat other animals or plants.
动物不能自己制造食物，比如植物，但它们吃其他动物或植物。
That is why they called consumers.
这就是为什么他们叫消费者。
There are three types of consumers, including primary [ˈpraiməri] consumers or herbivores (eat only plants), secondary [ˈsekəndəri] consumers or carnivores (eat others animals), tertiary [ˈtəːʃəri] consumer (carnivores eat other carnivores), and omnivores (eat animals and plants).

Animals are consumers
3、Facts about Food Chains 3: Decomposers
Bacteria, fungi, and worm belong to decomposers [ˌdiːkəmˈpəuzə].
细菌、真菌和蠕虫属于分解者
They eat dead plants and animals or decaying [diˈkei] matter.
它们以死去的动植物或腐烂的物质为食。
（The ground was scattered with decaying leaves地上散落着腐烂的叶子）
Decaying：v.腐蚀；衰退；消失 [物理]衰变；毁坏 n.腐烂；衰退 [物理]放射性蜕变；衰弱
Besides, they also returned back the nutrient [ˈnjuːtriənt] into soil which can be used by plants again.
此外，它们还将养分返还到土壤中，可供植物再利用。
4、Facts about Food Chains 4: Food chain
Food chain is started by plants and ended by animals.
食物链由植物开始，由动物结束。
Plants (grass) is eaten by primary consumers.
主要消费者以植物(草)为食。
The primary consumers (rabbit) is eaten by secondary consumers (fox).
第一消费者(兔子)被第二消费者(狐狸)吃掉。
For example, grass –> rabbit –>　　fox.

5、Facts about Food Chains 5: Trophic Levels营养级
Each level or position in the food chain is described by trophic [ˈtrɔfik] level.
食物链中的每个级别或位置都是由营养级别来描述的。
The first level is plants or producers.
第一层是植物或者生产者。
The second level is herbivores or primary consumers.
第二层是食草动物或主要消费者。
The third level is carnivores or secondary consumers.
第三层是食肉动物或第二消费者。
The fourth level is tertiary consumers.
第四层是三级消费者。
The fifth level is predators.
第五层是掠食者。
6、Facts about Food Chains 6: Food Web食物网
Food web is also called as food cycle.
食物网也被称为食物循环。
It is the end up of the all food chains of what eats what of chains.
它是所有食物链的终结，什么食物链吃什么食物链。

Facts about Food Chains 7: The concept of food chains
The concept of food chains is introduced by Al-Jahiz (African-Arab). He is a scientist and philosopher.
Facts about Food Chains 8: The importance of each link
Each link of food chains is very important.
食物链的每一环节都非常重要。
Because if we loss only one link, it will make the species become extinct [iksˈtiŋkt] . (We'll never see this creature again)
因为如果我们只失去一个环节，那么这个物种就会灭绝。

Energy loss along food chain
Facts about Food Chains 9: The populations of food chain食物链中的种群
The population of food chain depends on another population.
食物链的种群依赖于另一种种群。
It means that the population is affected by another one.
这意味着人口会受到另一个的影响。
For example, when there are more zebras than grass, the zebras will die.
例如，当斑马比草多时，斑马就会死。
Whereas the grass will grow properly, if there are fewer zebras.
然而，如果斑马数量减少，草就能正常生长。
The lion also will be die, if the zebra is rare [reə] .
如果斑马很稀少，狮子也会死。
Besides, the lion will increase [inˈkriːs] when there are fewer lions.
而且，狮子越少，狮子就越多。
Facts about Food Chains 10: The energy of food chain
Producers (plants) are the source of energy and another link just uses the energy.
生产者(植物)是能源的来源，另一个环节只是使用能源。
That is why the available [əˈveiləbl] energy is less through the move of food chain.
这就是为什么通过食物链的移动，可用能量较少的原因。

Plant is the source [sɔːs] of energy of food chain
　　植物是食物链的能量来源

很烧脑的一首食物链的儿歌！

The simple food chain

A food chain shows how each living things get food, and how nutrients and energy are passed from creature to creature. Food chain begins with plant-life, and end with animal-life.

Some animals eat plants, while others eat animals.

A simply food chain could start with grass, which is eaten by rabbits, then the rabbits are eaten by foxes.

GRASS--RABBITS--FOXES

At each link in the chain, energy is being transferred from one animal to another.

Food chains make a full circle, and energy is passed from plant to animal, animal to decomposer, and back to plant.

食物链游戏

At the bottom of the ocean food chain is phytoplankton, very tiny plants that float through the ocean. They get their energy from the sun. In the process, they produce half of the air we breathe. Thanks, phytoplankton!

Phytoplankton is eaten by zooplankton, very tiny animals that float through the ocean. They come in all different shapes; some look like tiny shrimp.

Zooplankton is eaten by small animals like seahorses and jellyfish.

They are both eaten by medium-sized animals like sea turtles and octopus.

And both of them are eaten by big animals like sharks. A shark is too big and fierce to be eaten by anything, so it’s called a top predator: it’s at the top of the food chain.

But an important thing to remember is that the creatures at the top could not live without the creatures at the bottom.

Even though the blue whale is the biggest animal of all, it doesn’t eat sharks. Instead, blue whales eat huge amounts of a very tiny creature: a type of zooplankton called krill.

GO FOR A WALK IN NATURE AND LOOK AT THE ANIMALS YOU SEE.

What do they eat?

What eats them?

You can even make nesting dolls for them, too.

What kinds of animals and plants do you eat?
