Clean energy resources,however,are renewable.So we can make use of Theme 自然生 them as long as we want to. Thirdly,it helps to make a better environment.Clean energy works as a substitute for 态 traditional energy like oil,which brings problems to our environment.By using clean energy, we can reduce global warming and greenhouse gas emission. Much remains to be done to figure out more about clean energy and how to use them to their best advantage.And these are the mysteries for us to explore.

First you may think oxygen comes from forests.Well,a lot of oxygen comes from trees in the forests.The Amazon Rain Forest is the largest forest in the world.It gives us half of the oxygen we need.People often call the Amazon Rain Forest as the lungs of the Earth. But most oxygen is not produced by land plants,but from the ocean.Because ocean 自 area accounts for 70%of the Earth's surface area,and forests account for only a small number of land areas.The 90%oxygen on the Earth comes from the ocean.So the ocean is 生 the"production machine"of oxygen.And oxygen is mainly from blue-green algae in the ocean.Before green plants appeared,blue-green algae was the main source of oxygen on the Earth. On the land,we say that the more plants,the better breath.But in the sea,if blue-green algae grow too much,it will make oxygen less.So we need protect the ocean from growing more blue-green algae.

The food chains consist of producers,consumers and decomposers(分解者).Plants are producers..They absorb sunlight,water and other nutrient from the soil.Their leaves make food.Plants are the only living beings that create new energy for other living beings. Animals are consumers.This is because they don't produce energy.Animals that eat plants are called primary consumers or herbivores.Animals that eat other animals are called secondary consumers or carnivores.If a carnivore eats another carnivore,it is called a tertiary (consumer.Some animals eat both plants and animals,so they are called omnivores. Bacteria and fungi (are decomposers.They break plants and animals down and decompose them.When that happens,decomposers release nutrient and energy back into the soil.And then,the nutrient and energy will be used by the plants again. Humans are at the end of food chains.They eat both plants and animals to get energy.A food web is a natural interconnection of different food chains.There are so many food webs in our nature,for example,food webs in lakes,in mountains and on the grassland. 自然生 me ABC 生词积累 food chain食物链 survival/svav(a)l/n.幸存；存活 consist of包含；由…组成 nutrient/nju:triont/,n.养分；养料 herbivore/'h3brvo(r)/n.食草动物 carnivore/ka:nivo(r)/n.食肉动物 omnivore/pmnivo:(r)/n.杂食动物 bacteria/baek'tioria/n.细菌 提优训练 根据短文内容，判断下列句子正(T)误(F)。 ()1.The food chains consist of producers,consumers and decomposers.
