Across
- 5. The specific place where an organism lives within an ecosystem, characterized by its physical and biological features.
- 6. An organism that obtains its food by consuming other organisms, either as herbivores (eating plants), carnivores (eating animals), or omnivores (eating both plants and animals).
- 8. The body system that allows us to breathe and take in oxygen, while also getting rid of waste gases like carbon dioxide.
- 11. The amount of space an object occupies, measured in units such as liters or cubic centimeters.
- 12. A trait or characteristic that helps an organism survive and thrive in its environment, such as camouflage, sharp teeth, or strong wings.
- 15. The body system that helps break down food into smaller parts so that the body can absorb the nutrients it needs for energy and growth.
- 17. The body system that controls and coordinates all the activities of the body, including our ability to think, move, and feel.
- 19. An organism, such as fungi or bacteria, that breaks down dead plants and animals into simpler substances, recycling nutrients back into the ecosystem.
- 20. An animal that is hunted, killed, and eaten by a predator.
- 22. An animal that hunts, kills, and eats other animals.
- 23. The body system that provides structure and support to our bodies, including our bones, joints, and connective tissues.
- 24. A state of matter with a definite volume but no fixed shape, where particles are loosely packed and can flow.
Down
- 1. An organism, usually a plant, that is capable of making its own food through photosynthesis.
- 2. A community of living organisms, including plants, animals, and microorganisms, interacting with each other and their environment.
- 3. The body system that helps protect our bodies from harmful germs and diseases by recognizing and fighting off invaders.
- 4. The body system responsible for pumping blood and delivering oxygen and nutrients to all parts of the body through a network of blood vessels.
- 7. The amount of matter in an object, measured in units such as grams or kilograms.
- 9. Anything that has mass and takes up space, including solids, liquids, and gases.
- 10. chain: The sequence of organisms, from producers to consumers to decomposers, through which energy and nutrients flow in an ecosystem.
- 13. The body system responsible for movement and allowing us to perform activities like walking, running, and lifting objects.
- 14. The measure of how much mass is packed into a given volume, calculated by dividing mass by volume.
- 16. The variety of life within an ecosystem, including the number of different species and their abundance.
- 18. A state of matter with a fixed shape and volume, where particles are tightly packed and vibrate in place.
- 21. A state of matter with no definite shape or volume, where particles are widely spaced and move freely.
