问题 填空题

如图为某生态系统中食物网的一部分:

(1)该食物网中有______条食物链.

(2)该食物网中______是生产者.______、______、______、______是消费者.

(3)消费者与生产者之间的关系是______的关系

(4)假设有毒物质污染了草,长此以往这个食物网中体内积累有毒物质最多的生物是______,所以保护环境就是保护我们自己.

答案

(1)、食物链反映的是生产者与消费者之间吃与被吃这种关系的,所以食物链中不应该出现分解者.食物链的正确写法是:生产者→初级消费者→次级消费者…注意起始点是生产者.数食物链时,应从生产者开始,沿着箭头向上到最高级消费者.该食物网中有2条食物链分别为①草→昆虫→鸡→人,②草→牛→人;

(2)、生产者是指能进行光合作用,为植物自身、消费者、分解者提供有机物(食物)和氧气的绿色植物.因此,此生态系统的生产者是草;消费者是指不能进行光合作用,必需以现成的有机物为食的动物.不包括腐生动物;因此,昆虫、鸡、牛、人是消费者.

(3)、食物链反映的是生产者与消费者之间吃与被吃这种关系的,生产者被消费者吃,消费者吃生产者.因此,消费者与生产者之间的关系是吃与被吃的关系

(4)、我们知道有毒物质会在生物体内进行生物富集,所以生物的营养级别越高体内的有毒物质就越高.故体内有毒物质积累最多的生物是人.

故答案为:

(1)、2

(2)、草;昆虫;牛;人

(3)、吃与被吃

(4)、人

A conflict at work is common. If you can avoid conflict, it means you will win what you want regardless of what the other person wants. Since the potential issue has not been removed, it will simply reappear later. Let’s see what you can do.
★Be aware of the fact that some conflicts are unavoidable at work. On numerous occasions, conflict and disagreement are likely to happen. But when a conflict happens it's not the end of the world. On the contrary, it can be the beginning of an interesting learning process. Conflicts mean that people care enough to disagree strongly. The trick is not to allow the conflict to go on forever.
★ Deal with conflicts sooner rather than later. Solve a conflict when it starts, as it only gets worse with time going by. Conflicts at work arise not from something that was said, but from something that wasn't said! Everyone's waiting for the other to admit he's wrong and gets more unpleasant after the conflict has lasted a while. It's essential to interrupt the "waiting game" before it gets to that point.
★Ask nicely. If somebody has done something that made you angry, or if you don't understand their viewpoint or actions, simply asking nicely about it can make a world of difference.  Never assume that people do what they do to annoy or hurt you. Sometimes there's a good reason why that person does what he or she does, and a potential conflict disappear right there. Do remember to make an inquiry, not an accusation of any sort.
★ Appreciate. Praise the other part in the conflict. Tell them why it's worth it to you to solve the conflict. This can be difficult as few people find it easy to praise and appreciate a person they disagree strongly with, but it's a great way to move forward.
