    Importance of Animal Behavior
    ::动物行为的重要性

    Why do animals behave the way they do? The answer to this question depends on what the behavior is. A cat chases a mouse to catch it. A mother dog nurses her puppies to feed them. All of these behaviors have the same purpose: getting or providing food. All animals need food for energy . They need energy to move around. In fact, they need energy just to stay alive. Energy allows all the processes inside cells to occur. Baby animals also need energy to grow and develop.
    ::为什么动物的行为方式? 这个问题的答案取决于行为是什么。 一只猫追逐一只老鼠来捕捉它。 一只母狗喂养小狗喂养小狗。 所有这些行为的目的都是一样的: 获取或提供食物。 所有动物都需要食物作为能源。 它们需要能量来移动。 事实上, 它们需要能量来生存。 能量可以让细胞内的所有过程发生。 婴儿也需要能量来生长和发展。

    Birds and wasps build nests to have a safe place to store their eggs and raise their young. Many other animals build nests for the same reason. Animals protect their young in other ways, as well. For example, a mother dog not only nurses her puppies. She also washes them with her tongue and protects them from strange people or other animals. All of these behaviors help the young survive and grow up to be adults.
    ::鸟类 和 黄蜂 建立 巢穴 、 以 安全 的 地方 储存 卵 、 养育 幼鸟 。 许多其他 动物 也 以 相同 的 理由 建立 巢穴 。 动物 也 以 其它 方式 保护 幼鸟 。 例如 , 母狗 不仅 保护 小狗 、 也 用 舌头 洗 、 保护 其 不受 陌生 人 或其他 动物 的 伤害 。 所有这些 行为 都 帮助 年轻人 存活 、 长大成人 。

    Rabbits run away from foxes and other predators to stay alive. Their speed is their best defense. Lizards sun themselves on rocks to get warm because they cannot produce their own body heat. When they are warmer, they can move faster and be more alert. This helps them escape from predators and also find food.
    ::兔子逃离狐狸和其他捕食者而求生存。它们的速度是它们最好的防御手段。蜥蜴在岩石上晒太阳以取暖,因为它们不能产生自己的体温。当它们变暖时,它们可以更快地移动,更加警觉。这有助于它们逃离捕食者,找到食物。

    All of these animal behaviors are important. They help the animals get food for energy, make sure their young survive, or ensure that they, themselves, survive. Behaviors that help animals or their young survive, increase the animals’ fitness . Animals with higher fitness have a better chance of passing their genes on to the next generation. If genes control behaviors that increase fitness, the behaviors become more common in the species . This occurs through the process of evolution by .
    ::所有这些动物行为都很重要。 它们帮助动物获得食物以获取能量,确保它们的幼年生存,或确保它们自己生存。 帮助动物或幼年生存的行为会增加动物的体质。 健康程度较高的动物更有可能将其基因传给下一代。 如果基因控制着提高健康程度的行为,它们的行为就会在物种中变得更为常见。 这通过进化过程发生 。

    Summary
