Our planet is home to thousands of species of animals, both big and small. Though some may not be as cute and cuddly as the others, each animal plays an important role in keeping our earth's ecosystem healthy and balanced. Whether they are herbivores or carnivores, each animal's unique characteristics help to maintain the delicate balance of nature.
我们的星球是成千上万种大小不一的动物的家园。尽管有些动物可能没有其他动物那样可爱和招人喜欢，但每种动物在保持我们地球生态系统健康和平衡方面发挥着重要作用。无论它们是草食动物还是食肉动物，每种动物独特的特征都有助于维持自然的微妙平衡。
