2. What Animals Need: Food Water Shelter Air

3. Animals that live on land, such as giraffes, have lungs that get oxygen from the air. Insects get oxygen from the air through tiny holes in their bodies. Water animals, such as fish, get their oxygen from water. However, other water animals, such as whales, must come to the surface and breathe air to get oxygen.

4. Bodies of animals contain water. When an animal pants or sweats, it loses some water from its body. Animals must replace lost water in order to stay alive. How animals replace lost water: Drinking – puddles, streams, rivers, ponds or lakes From water in the foods they eat

5. Food gives animals what they need to grow and stay healthy. Animals get energy from food. Animals can’t make their own food: Food from eating plants Food from eating other animals Food from eating both plants and animals Animal use their body parts to get their foods. Trunks Claws Tongue

13. 1. Young frogs hatch from eggs begin life in water 2. Breathe with gills (body part that takes in oxygen from the water) 3. Young frogs change and in time they form lungs. At this time their gills begin to disappear. They also develop other body parts that will help them live on land. 4. Once lungs work and gills and tail disappear, the adult frog is now ready to live on land.

14. Fish Traits Live whole lives in water Breathe with gills Scales (small thin flat plates protect fish Eat plants and other animals trout grouper shark Stingray swordfish

15. Scales: help fish glide thru water Body shape: allows them to move easily thru water Gills: take in oxygen from water Tail fin: allows fish move side to side Fins: allow fish to move forward and backward or turn in other directions

16. Some fish carry their eggs inside their bodies until eggs hatch. Most fish lay eggs in water Some fish care for eggs by guarding them Most fish leave their eggs alone after their laid Young fish are very small when they are hatched and must find their food and avoid enemies without help from parents
