  1. The word "ecosystem" is short for ecological (生态的) system. An ecosystem is whereliving creatures expand within a given area. You can say that an ecosystem is the naturalenvironment where biological organisms (生物) such as plants, animals and humans co-existin this world. So naturally that includes you and me. Yes, we are all members of anecosystem !

  2. There are different kinds of ecosystems depending on the type of surface or environment.Most are naturally made such as the ocean or lake and the desert or rainforest. Some areman-made or artificial to encourage co-habitation (合居) between living and non-livingthings in a monitored environment, such as a zoo or garden.

  3. Plants make up the biggest group of biological creatures within an ecosystem, and that'sbecause they are the natural food producers for everyone. Plants raised in the earth need airand collect sunlight to help them grow. When they grow, the plants and its fruits or flowerseventually become a source of food to animals, microorganisms (微生物 ) and evenhumans, of course. Food is then converted to energy for the rest of us to function, and thishappens in a never-ending cycle until the living creatures die and break up back in the earth.

  4. Ecosystems are the basis of survival for all living things. We depend on plants and animalsfor food. In order for us to exist, we need to grow and care about other organisms. We alsoneed to care for the non-living things within our environment like our air and water so we cancontinue living as a population. Since plants, animals and humans are all of various species(物种), we all play a role in maintaining the ecosystem.

  5. To preserve our ecosystems, we should stop using too much energy, which happens when weconsume more than our share of resources. Humans should not disturb the natural habitat ( 栖息地) of plants and animals, and allow them to grow. healthily for the cycle to continue.Too many people in a habitat can mean displacement (搬迁): imagine being thrown out ofyour home because there is no more space for everyone. Worse, overpopulation can also ruinthe environment and cause destruction of existing plants and animals.
