袋鼠生活在澳大利亚，塔斯马尼亚和周围岛屿的各种栖息地，如森林，林地，平原和稀树草原。根据物种的不同，袋鼠在生态系统中占据不同的位置。袋鼠是食草动物，它们的饮食主要由各种植物组成，如草，灌木和花。有些物种也可能吃真菌和苔藓。袋鼠生活在被称为“暴徒”的群体中，也被称为部队或牧群。这些暴徒通常由该群体中的优势男性领导。与奶牛类似，袋鼠可能会将食物反刍，将其作为咀嚼物咀嚼，然后再次吞咽。这种行为在袋鼠中比在反刍动物中更罕见。袋鼠胃与奶牛和类似动物的胃不同;虽然袋鼠和奶牛都有胃，但各自胃里的发酵过程却不同。与奶牛不同，袋鼠的过程不会产生太多甲烷，因此袋鼠对全球甲烷排放的贡献不如奶牛。

Kangaroos live in Australia, Tasmania and the surrounding islands of various habitats such as forests, woodlands, plains and savannas. Depending on the species, kangaroos occupy different positions in the ecosystem. Kangaroos are herbivores whose diet consists mainly of various plants such as grasses, shrubs and flowers. Some species may also eat fungi and moss. Kangaroos live in groups known as “thugs,” also known as troops or herds. These thugs are usually led by dominant men in the group. Like cows, kangaroos may ruminate food, chew it as a chew, and swallow it again. This behavior is more rare in kangaroos than in ruminants. The kangaroo stomach is different from the stomach of cows and similar animals; although kangaroos and cows have stomachs, the fermentation process in their stomachs is different. Unlike cows, the kangaroo process does not produce too much methane, so kangaroos contribute less to global methane emissions than cows.
