Hi there! I am Studyfin, your science tutor. Today, we will explore how amazing plants and animals survive in their homes!
Every living thing has structures that help it survive. In a plant, the roots, stems, leaves, flowers, and seeds each do a different job that helps the plant survive and reproduce in its own environment.
Let us compare two different plants. A desert cactus has thick stems to store water. A water lily has wide leaves that float on top of ponds to catch sunlight.
Animals also inherit structures and behaviors suited to where they live. These adaptations help them get food and water, avoid predators, and survive changes in their environment.
Compare a desert jackrabbit and a forest brown bear. How do their body parts help them stay at the right temperature?
- First, look at the jackrabbit. It lives in a very hot desert.
- Identify its key structure: it has huge, thin ears.
- Explain how this helps: warm blood flows through its ears, and the heat escapes into the air to cool the rabbit down.
- Next, look at the brown bear. It lives in cold forests.
- Identify its key structure: it has thick fur and a layer of fat.
- Explain how this helps: the thick fur traps heat close to its body to keep it warm.
- Finally, compare them: the rabbit uses thin ears to lose heat, while the bear uses thick fur to keep heat.
