 Life science review By: Sydney George

1. Draw and label a diagram of the water cycle. Be sure to include its source of energy.

2. What happens during condensation? Does Earth only experience condensation in the clouds? Why or why not?  Condensation happens when: The air gets cooler, and then water vapor changes to tiny droplets of liquid water.  Condensation DOESNT only happen in the clouds. I know this because, One day I was drinking coffee and when I was done, there was tiny water droplets on top of my cup lid.

3. Draw and label a diagram of the carbon dioxide and oxygen cycle.

4.Describe the differences in inherited vs. learned behaviors. Give 5+ examples of each.  Inherited traits: Its what you get from your parents. Ex: Brown hair, blue eyes, freckles, double jointed, skin color. Learned behaviors: What you learned, not what is related. Ex: Dog fetching bone, swimming, learning a new game, learning new sport, learn things in school.

5. Define the following and give at least 2 examples for each.  Producer: Something that makes its own food. Ex: plant  Consumer: An organism that gets energy by eating other organisms. Ex: Racoon  Decomposer: Living things that get energy from dead plants and animals. Ex: Bacteria  Herbivore: A consumer that only eats plants. Ex: Giraffe  Omnivores: A consumer that eats plants and animals. Ex: Black bear.

 Scavengers: Animals that get energy by eating dead animals instead of hunting. Ex: Vulture  Niche: A special job of an animal in the web of life. Ex: A spider because it takes care of the pest patrol.

6. How are the teeth different of a herbivore vs. a carnivore? Can they decide one day to change their diet? Why?  Herbivore teeth: Great teeth for grinding up leaves.  Carnivore teeth: Sharp for tearing prey.  Could they change their diet? Why?: No, they cant change their diet because, their teeth was made for the food they eat, not any other food.

7. Put the following food chains in the correct order and identify the following organisms as producer, consumer, predator, prey, or scavenger.  #1: Sun, seaweed (producer), seal (consumer, predator, prey), polar bear (consumer, predator).  #2: Sun, grass (producer), rabbit (consumer, prey), hawk (consumer, predator, prey), vulture (consumer, predator, scavenger).

8. List 4 different possibilities that would happen if one of the organisms in your food chains from #7 died  1. If we lose the sun, there wont be any living things anymore.  2. If we lose grass, we then lose rabbits, then hawks, then vultures.  3. If we lose seals, seaweed population will over populate and polar bears will die.  4. No polar bears, then we’ll have a over population of seals.

9. Define and list the similarities and differences in complete and incomplete metamorphosis. Complete Incomplete Has pupa No pupa No nympth Has nympth Both have adult Both egg Egg Larva Pupa Adult Egg Nympth Adult

10. Describe the function/purpose of each plant part: seed, flower, leaf, stem, root.  Seed: Holds part of the plant. Aka: The baby plant.  Flower: Produces seeds through pollination to make more plants.  Leaf: Makes food through photosynthesis.  Stem: Carries water and nutrients from the roots to the rest of the plant.  Root: To suck up water and nutrients from soil and anchors plant down to ground.

11. Do all plants need the same amount of sunlight, water, and nutrients in the soil? Explain with examples.  No, because cacti can survive without water for a long time and spends most of its days in the sun. While elephant ear plants in the jungle don’t get a lot of sunlight and get a lot of water. So not all plants need the same amount of sunlight, water, and nutrients.

12. List the 3 ways seeds mainly travel. Include pros and cons for seeds being able to travel.  1: Wind; Pros: Very fast. Cons: It isn’t always windy.  2. Water; Pros: Seeds travel fast. Cons: Can be drunken by animals.  3. Animals; Pros: Can travel farther distance. Cons: Can be brushed off.

13. List 4+ possibilities how a plant population would decrease.  1. They were in a too much hot climate and the plant may not like heat.  2. Disease  3. Over populated animals, eat the plants.  4. A drought.

14. Choose an animal that lives in a desert and describe 3 adaptations (1 adaptation must help it survive in its climate).  My animal I choose is a camel.  1. Stores water inside humps on back.  2. Spits saliva at predators.  3. Hooved feet great for walking in desert.

15. Describe how a cactus adapts and its niches in its environment.  Cactus’ adaptations: Stores water inside its body. Its roots don’t go deep into the ground but stay near the top of the surface to collect more water.  Cactus’ niches: Some have fruits, which animals eat. Creates shelter for some animals. Keeps animals out of danger.

16. Describe a deciduous forest biome in detail with pictures. Include plants, animals, amount of sunlight, spacing, etc.  Plants: Lichen, moss, broad leaf trees  Animals: Raccoons, deer’s, foxes.  Amount of sunlight: Warm and humid.  Spacing: Lots of space.  Extra info: Soil is rich, 6 month growing season.

17. Describe a tundra biome and the organisms in it. Include plant and animal adaptations for survival.  Tundra biome…….. Organisms that live there and their adaptations to survive: Coniferous trees. Cone shaped promotes shedding of snow and the “leaves” never shed, which means all year round photosynthesis. Artic foxes fur blends in with the snow so prey doesn’t see it coming. Artic hare does the same thing except that it hides from predators.
