食草动物

Consequently, changes in diversity at higher trophic levels can significantly alter ecosystem function in natural systems.

这一作用使得生态系统能够缓冲食草动物和植物丰度的较大变化，从而保持食物链的稳定。

This was the first suggestion of algal defenses against grazing.

这是最早有关水藻抵御食草动物的吞噬所作出的暗示。

Gested,but did not prove, that the grazers had removed most of the algae.

在存在大量食草动物的同时却只有少量的水藻花粉囊，这暗示出——但没能证明——食草

If woman had a free hand in the world'S marketing,the race would become graminivorous.

如果说女人在世界的交易场中能够自由自在的话，那么她们就会变成温顺的食草动物。

Most herbivores feed in secondary forests because pioneer species in secondary forests do have little or no mechanical or chemical protection against herbivores and many early and late seral tree species in secondary forests produce edible fruits in large quantities. Environment and fire have some effects on secondary forest succession. In early succession, relatively more biomass is allocated to resource acquiring tissues and in later stages more is allocated towards structural materials.

大多数食草动物喜欢在次生林中取食，因为次生林中的先锋树种很少或没有机械和化学保护和林内许多树种产生大量可食用的果实；环境和火对次生林演替有一定影响；在早期的演替过程中，更多的生物量分配到资源需求旺盛的组织，在演替晚期阶段，更多的生物量则分配到结构组织中。

Almost all life in the savanna depends on the grass; and carnivores lurk in it stalking herbivores, who eat it.

几乎所有的生命都要依赖热带草原的草丛活命，而食肉动物潜伏在草丛中，准备猎杀吃掉食草动物。

They -- they can provide greasing grazing animals with shame shade from the sun .

树还有其他的作用，可以为放牧的食草动物遮荫。

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。
