2. Water cycle Water cycle 1. Draw and label a diagram of the water cycle. Be sure to have the following label:Evaporation, condensation, precipitation, runoff, transpiration, and accumulation

3. Condensation 2. What happens during condensation? Does Earth only experience condensationin the clouds? Why or why not? Condensation happens when water vapor turns to liquid water in the clouds. Condensation can only happen in the clouds because when the water vapor turns from liquid water the cloud gets heavy so than it starts to rain, sleet, hail, or snow.

4. Carbon-dioxide/oxygen cycle 3.If we had too many plants, then we would have too much oxygen in the air if we had too may animals or pollution, then we would have too much carbon-dioxidein the air.

5. Inherited traits vs.learned behavior 4. Describe the difference in inherited traits vs. learned behavior. Give 5+ examples of each Inherited traits are traits that are passed down from your parents. • Color of eyes • Color of skin • Color of hair • Size • If an animal has spots Learned behavior are taught to you • To jump • To walk • To write • To drive • To cook

6. food web and food chain 5.Define the following & give at least 2 examples of each. Producer: an organism that makes its own food. ex: plant and animals Consumer: an organism that cant make their own food and so eat plant or animals. ex: people, foxes, and rabbits Decomposer: dead plant or animal that gives off nutrients ex:plants and fungi Herbivore: plant eater ex:rabbits and white tailed deer Omnivores: eats both plants and animals ex:humans and black bear Scavengers: animals that eat of all ready dead animals ex: vulture and Hyenas Niche: a role a organism plays in its ecosystem. ex: horse fly: Decompose organic matter Honey bee: Pollinate flowering plants

7. Herbivore vs. carnivore 6. Herbivores teeth are flat so the can rip the plants. Carnivores teeth are sharp so they can rip the meat If they try to change their diet it could hurt them. Like for instance if a herbivore ate meat it could hurt it and its teeth could not rip the meat. If a carnivore ate plants it wouldn’t digest good.

8. food chain 7. sun->seaweed->seal -> polar bear #1. #2. Sun->grass->rabbit->hawk ->vulture

9. Food chain 4. List 4 different possibilities that would happen if one of the in the food chain died Go to question 7 • If the seals died the polar bears would too • If there was no sun the seaweed would die so would the seals and the polar bears • If there were no polar bears than the seals would over populate • If the seals die than the seaweed would over populate.

10. On another sheet of paper

11. Plant parts • Seed- helps the flower reproduce • Flower- the color can worn predators • Leaf- makes the food and gets sun light • Stem- water and nutrients go up and back down the steam • Roots- absorb the water and get nutrients from the ground Question 10.

12. Do they need it? 11. Some plant like flowers need a lot of sun light but trees need more sun light because they are bigger. Some plants need different soil like vegetables need soil that don’t harm the vegetable. They all need the same amount of nutrients trees might need a little more because they need it for photosynthesis.

13. How do they travel? • Fly- they can disperse better(pro). They can also fly and plant next to each other(con). • Carried- from a animal. Can be carried to a new habitat(con). They can be carried and drop in the right habitat. • Eaten- animals can eat them. Might not plant (con). Animals might not eat them.

14. Plant population 13. Plant population can decrease by….. • Pollution • No water • No sun light • No room to grow • Wrong habitat

15. lizard 14. Adaptations • Scales • Can climb • Tall that can regrow if it is cut off. • Can blend in with the sand to hide from predators.

16. cactus 15. Cactus’ adaptations: Spines to protect it self from predators. And can hold water Cactus’ niche: Is to store water for the camels and to protect other animals.

17. Deciduous forest biome 16. Plants- has oak and hickory trees that absorb more water. In addition there are American Beech plants Animals- the white tailed deer, American Bald Eagle, etc.. Amount of sun light- varying amount of sun light. Spacing- a far amount of space. • Extras- Temperature • -30°C to 30°C, yearly average is 10°C, hot summers, cold winters • Precipitation • 750 to 1,500 mm of rain per year

18. Tundra 17. Organisms-Herbivorous mammals like: lemmings, voles, caribou, arctic hares and squirrels Carnivorous mammals like: arctic foxes, wolves, and polar bears Adaptations of the animals are that they ether have fat or have thick fur to keep warm.
