1. Find a picture of an animal with an adaptation and explain how the adaptation is going to help that organism survive in it's environment.
This animal's white fur lets it become invisible in a snowy environment.
2. List 2 ways humans have caused changes in populations of organisms. Humans who hunt for game Pollution can kill species in the environment 3. How have humans negatively affected various populations? Pollution and hunting have limited the amount of species in the environment 4. What would happen to other organisms in a marine food web if human impact negatively affected one type of organism? Organisms that depend on that organism can die from starvation or overpopulation 5. How has over harvesting or over fishing negatively affected the aquatic ecosystem? The acts against the aquatic ecosystem causes scarcity in populations of fish 6. What is bacteria's role in the ecosystem? How do they obtain nutrients? Bacteria has a wide range of environmental benefits. They obtain nutrients through minerals. 7. Describe a producer/consumer relationship in the food web below. Phytoplankton and zooplankton; the producer provides food for the consumer
8. Find a picture of a parasite/host relationship and explain which organism is the parasite and which one is the host. The mosquito is the parasite because it benefits from the human but the human is the host because we are harmed from it.
9. Describe a predator/prey relationship in the food web below. Owl/Mouse. The owl hunts the mouse and feeds on it 10. How many atoms are present in the molecule below? 24
11. How do you know by looking at a bohr model which elements are in the same group? Valence electrons 12. What information is given when we have the chemical formula for a substance? The elements and how many atoms are present
13. Describe evidence of a chemical reaction. There are bubbles occurring 14. Does the equation below follow the Law of Conservation of Mass? No because the amount of atoms are not balanced
15. How do valence electrons tell us how reactive an element is? The more valence electrons, the less reactive it will be because they almost have a full shell. 16. Describe examples of chemical and physical changes in the digestive system.
Chemical- stomach acid tearing your food apart. Physical- teeth chewing your food
