捕食生物的

There exist competition, predation mutualism and synergism among acidophilic microorganisms. The study on these interactions is very important to understand bioleaching process.

总结了嗜酸微生物群落间存在竞争、捕食、共生、合作等相互作用关系，这对理解矿物的生物浸出具有重要意义。

具体内容包罗万象：气候学和生物气象学；降雨和它的生物影响；沉积物的腐蚀和沉积；沙丘结构和形成；干旱地区的植物和动物群；寄生物和捕食动物；干旱地区的人类学和社会学；干旱地区的绿地建设；水控制和干旱地区的沙漠化的成因和控制等。

3The ecosystem biodiversity concept - A Venus flytrap can prey on and dissolve living creatures, so its role in nature is a consumer.

生态系多样性层面─认为捕蝇草会捕食及分解其他生物，所以在自然界的角色是消费者。

There are as well as density-dependent biological factors such as disease, predation, and intraspecific conpetition.

还有密度制约的生物因素，诸如病害、捕食和种内竞争等。

While purple-toed, keen-eyed hunters are just a made up example, a real animal that demonstrates this is the three-spined stickleback fish of western Canada. These fish moved into glacier-carved lakes thirteen thousand years ago. Over time, they evolved into two separate species.

紫色脚趾、厉眼的捕食者只是一个例子，而在加拿大西部海域有一种真实的生物名叫三椎棘鱼论证了这一进化历程。3000年前，这种鱼类迁徙到了布满冰川的河流，随着时间过去，他们演变成两种不同的生物种类。

"Also, try to find out any special inter-relationship between the living organisms, for example, competition, mutualism and parasitism."

另外，亦尝试寻找生物之间的相互关系----包括竞争、共生、捕食和寄生。

"Clearly this new fossil would have been part of the food-chain, both as predator and prey," said Bloch, who co-led the fossil-hunting expeditions to Cerrejon with Smithsonian paleobotanist Carlos Jaramillo.

显然，如果能活到现在的话，无论是从作为捕食者还是被捕食者的角度来看，这种生物肯定是食物链中的一环。

Simian3 and Shiyuan321 as control. It showed that both GK12 and SGK321 had no significant impacts on natural control efficacy of the biological and non-biological death factors of cotton aphids. Except for the factor of natural death and others, predation was the key factor affecting population dynamics of cotton aphid. Rain ranked the second, parasitism by insects and pathogens had weak control efficacy.

与常规棉相比，单，双价抗虫棉对天敌捕食和寄生，病原物，风雨等生物和非生物因素对棉蚜种群的自然控制作用均未产生显著影响；各因素中，除自然死亡及未知因素死亡外，天敌捕食对棉蚜自然种群的控制作用最强，风雨的作用次之，天敌寄生和病原物的作用则较弱。

These activities are dependent on environmental factors, including nutrient levels, the availability of alternative substrates, predation, population density, contaminant substrate concentration, pre-exposure, and bioavailability.

这些活动依赖于环境因素，包括营养水平，替代物，捕食，人口密度，底物浓度的污染物，暴露前可用性和生物利用度。

参考答案：这些活动依赖于环境因素，包括营养水平，替代物，捕食，人口密度，底物浓度的污染物，暴露前可用性和生物利用度。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
