Across
- 4. brings oxygen to the blood and remove carbon dioxide
- 7. storage of urine until full and then you urinate.
- 8. breaks down food even more and then it absorbs all the nutrients back into the blood
- 9. first level of the food chain because they can produce/make their own food from the sun.
- 10. anchor the plant and takes in water and nutrients from the soil
- 11. the type of metamorphosis with four stages in an insects life cycle in which it undergoes a complete physical change.
- 12. control center of body that carries information back and forth between brain and organs.
- 14. take in carbon dioxide from the air and absorb sun light from sun to make food through photosynthesis
- 15. second level of the food chain because they eat plants.
- 16. surrounds the egg and provides nutrients. It will develop into fruit.
- 17. surround the reproductive organs and attract pollinators.
- 20. animal group with moist smooth skin, eggs, gills and lungs, cold blooded
- 21. third level of the food chain because they eat plants and animals.
- 22. cleans the blood coming from the digestive organs and changes food into forms that can be stored. Bile neutralizes stomach acid.
- 23. parts of the plant when fertilized with pollen develop into a seed
- 25. helps the plant reproduce. Has the male and female part of the plant.
- 26. animal group with feathers, lay eggs, lungs, warm blooded
- 28. does not have a backbone but sometimes have a hard outer covering called an exoskeleton.
- 29. animal group with hair/fur, live birth, lungs, warm blooded
- 31. fourth level of the food chain because they eat only animals.
Down
- 1. Pumps and keeps blood flowing through the body.
- 2. filters harmful things out of your blood, regulate the amount of water in your body and then sends waste (urine) to bladder
- 3. the type of metamorphosis with three stages in its life cycle in which the animals and insects look like smaller versions of an adult.
- 5. provide support and allow water and nutrients and food to travel through the plant.
- 6. animal group with hard scales, eggs, lungs, cold blooded
- 8. an adaptation that is a part of the body that help an organism to survive and reproduce.
- 13. organisms that eat to gain energy.
- 14. absorbs water back into the blood.
- 17. releases chemicals that break down food into the small intestines and it releases insulin that is used to break down sugar.
- 18. fertilized egg that grows into a new plant.
- 19. animal group with scales, eggs, gills, cold blooded
- 24. have a backbone
- 27. an adaptation that are behaviors (how an organism acts) that help it survive and reproduce.
- 30. crushes the food and then release stomach acid to further break down food.
