Life science Review Homework

Water cycle1. Draw and label a diagram of the water cycle. Be sure to have the following label: Evaporation,

condensation, precipitation,

runoff, transpiration, and

accumulation

Water cycle

Condensation2. What happens during condensation? Does Earth only experience condensation in 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.

Carbon-dioxide/oxygen cycle3.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-dioxide in the air.

Inherited traits vs. learned behavior4. 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.1) Color of eyes2) Color of skin3) Color of hair4) Size 5) If an animal has spotsLearned behavior are taught to you6) To jump 7) To walk8) To write 9) To drive 10) To cook

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 animalsConsumer: 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 fungiHerbivore: plant eater ex: rabbits and white tailed deerOmnivores: eats both plants and animals ex: humans and black bearScavengers: animals that eat of all ready dead animals ex: vulture and HyenasNiche: a role a organism plays in its ecosystem.ex: horse fly: Decompose organic matterHoney bee: Pollinate flowering plants

Herbivore vs. carnivore6. 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.

food chain7. sun->seaweed->seal -> polar bear#1.

#2.

Sun->grass->rabbit->hawk->vulture

Food chain4. List 4 different possibilities that would happen if one of the in the food chain died

Go to question 7

1) If the seals died the polar bears would too

2) If there was no sun the seaweed would die so would the seals and the polar bears

3) If there were no polar bears than the seals would over populate

4) If the seals die than the seaweed would over populate.

On another sheet of paper

Plant parts1. Seed- helps the flower reproduce

2. Flower- the color can worn predators3. Leaf- makes the food and gets sun light

4. Stem- water and nutrients go up and back down the steam

5. Roots- absorb the water and get nutrients from the ground

Question 10.

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.

How do they travel?I. Fly- they can disperse

better(pro). They can also fly and plant next

to each other(con).II. Carried- from a animal.

Can be carried to a new habitat(con). They can be carried and drop in

the right habitat.III. Eaten- animals can eat

them. Might not plant (con). Animals might

not eat them.

Plant population13. Plant population can decrease by…..i. Pollutionii. No wateriii. No sun lightiv. No room to growv. Wrong habitat

lizard14. Adaptations Scales Can climb Tall that can regrow

if it is cut off. Can blend in with

the sand to hide from predators.

cactus15.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.

Deciduous forest biome16.Plants- has oak and hickory trees that absorb more water. In addition there are American Beech plantsAnimals- 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

Tundra17. Organisms-Herbivorous mammals like: lemmings, voles, caribou, arctic hares and squirrelsCarnivorous mammals like: arctic foxes, wolves, and polar bearsAdaptations of the animals are that they ether have fat or have thick fur to keep warm.
