Review Questions

• How do kangaroos contribute to the ecosystem in Australia?
  • Kangaroos are significant grazers in the Australian ecosystem, feeding on grasses and helping to manage plant growth. By consuming vegetation, they promote new growth and maintain healthy grasslands. Their grazing habits also influence the composition of plant communities, which can affect other species that share their habitat. This role is essential for maintaining biodiversity in the ecosystems where they live.
• Discuss the adaptations of kangaroos that allow them to thrive in the Australian environment.
  • Kangaroos have several adaptations that enable them to thrive in Australia's diverse environments. Their powerful hind legs allow them to travel long distances efficiently while conserving energy, which is crucial in arid regions. Their ability to obtain moisture from the food they eat helps them survive with limited water sources. Additionally, their fur reflects sunlight, keeping them cool during hot weather, while their social behavior allows them to live in mobs for safety against predators.
