#6 how are the TEETH different of a herbivore vs. a carnivore?can they decide one day to change their diet? why?
herbivore teeth: flat,wide,broad teeth made for chewing plants carnivore teeth: sharp,pointy,teeth made for ripping up their meat could they change their diet? why?-- NO--because they can't change their teeth

describe the function/purpose of each plant part: seed,flower,leaf,stem,roots.
seed:to produce more flowers/plants flower:to make the seeds through pollination leaf:makes food for the plant through photosynthesis stem:to carry water,nutrients,air,and sunlight up to the flower to make the food root:suck up nutrients and water from the soil/holds the plant in place

a lizard lives in a desert-describe 3 adaptations (1 adaptation must help it survive in its climate)
LIZARD 1:camouflage -protect its self/hide from predators 2:scaly skin-to survive in the heat 3:sharp little claws-to burrow underground and keep cool

#7 put the following food chains in the correct order down below
#1: Seal,seaweed,polar,bear,sun #2: Hawk,sun,rabbit,grass,vulture

do all plants need the same amount of sunlight,water,and nutrients in the soil? EXPLAIN WITH EXAMPLES.
NO-they have adapted to different environments. ex. cacti=desert has a lot of sunlight (clear)-not much water VS. ex. pine tree=cold mountains-cold and not much sunlight(clear)

describe how a cactus adapts and its niches in its environment
cactus' adaptations: needles are sharp to harm anything that trys to get its water. cactus' niches (jobs): water for animals and homes/food for birds

list 4 different possibilities that would happen if the rabbit in chain #2:, died
#2: 1:the grass would over populate 2:there would be less hawks 3:the vultures would just feed on the dead animals 4:the mice population will lighten because the hawk will only have that to eat

list the 3 ways SEEDS mainly travel.
1: wind 2:animals 3:water

describe a deciduous forest biome, include plants,animals,amount of sunlight,spacing,etc…...
plants-lots of different types of plants all go through seasons animals-herbivores-squirells,white tailed deer, chipmunks,bluejays,and chickadees-omnivores-racoon,possum,black bear-carnivores-foxes,coyotes,bobcats,wolves,snakes amount of sunlight-has a little more in the summer spacing-big with lots of trees extra info- soil is very rich in nutrients FOUR DISTINCT SEASONS EACH YEAR! In north america it often occurs from southeastern canada through the mountains of northern Georgia and west to the Mississippi River.
400
list 4+ possibilities how a plant population would decrease.
plants in an ecosystem could decrease if……….. 1:the carnivores died 2:there were only herbivores and they ate all of the plants 3:there was no sun 4:there was no carbon dioxide

describe a tundra biome & the organisms in it. include plant and animal adaptations for survival.
animals: arctic fox-has white fur to blend in and hide from their predator timber wolves- have fur that blends in with its surroundings plants: shrubs-tiny leaves- to retain moisture mosses-tiny rootlets instead of roots due to permafrost
