Differences between the ecosystems. |
Wetland- sunny and wet soil Forest- shady with out a lot of ground level plants. Infertile soil that isn't very wet or dry Prairie- very hot and dry with fertile soil |
|
|
Abiotic factors |
Wetland- wet soil/ rocks Forest- Shady/ infertile soil Prairie- fires/ fertile soil |
|
|
Biotic factors/ invasive species |
Wetland- cattails/ crayfiah/ dragonflies/ pickerel frogs/ etc. Purple loosestrife Forest- bur oak/ red bellied woodpecker/ squirrels/ moss/ etc. Earthworms Prairie- big bluestem/ goldenrod/ quails/ indian grass/ mice/ etc Buckthorn |

Food chain vs. Energy pyramid |
Both show what eats what Energy pyramid shows how energy is transferred from one level to the next Food chain just shows the organisms that depend on eachother for an energy source |

Plant organ systems and functions |
Shoot system- Organs: stems, leaves, phloem, xylem Functions: capture sunlight, do photosynthesis, support the plant, water and minerals move through the xylem, sugars move through the phloem Root system- Organs: roots (tap or fibrous) Functions: anchor and support the plant, take in water and minerals Reproductive system- Organs: pistil; ovary, style, stigma/ stamen; anther, filament Functions: makes seeds for new plants to grow, 1) pollen is made in anther. 2) Stigma captures pollen. 3) A seed is formed. |

Plant adaptations |
Big bluestem- Shoots: narrow and fuzzy leaves to conserve water, herbaceous stems grow back fast after fires Roots: tap root to reach deep into the soil for water Flowers: small flowers= short germination oeriod to grow back fast after fires, wind pollenates them over large areas Oak tree- Shoots: big leaves to capture the most sunlight, woody stems to support the tree so it can grow tall up to the sun Roots: wide roots to anchor the tree when it gets windy high up, fibrous roots don't go deep because soil isn't dry Flowers: male= catkins, female= acorns, bloom in spring to capture the most sun, lots of pollen for the wind to blow around Cattails- Shoots: woodyish stems hold them up out of the water, aerenchyma let them take in air through their stems Roots: fibrous to anchor them in the wet soil, have rhizomes so they can spread through their roots too Flowers: seeds are too small to be eaten, spread by wind over large areas, flower in summer |

Human organ systems |
Digestive system (mouth, allimentary canal, esophagus, stomach, small intestine/ large intestine, anus [pancreas, liver, gall bladder])- Take in nutrients, break down nutrients, get nutrients into blood, gets rid of food waste Circulatory/ respiratory systems (heart, lungs, arteries, veins)- Take oxygen in and release carbon dioxide, move nutrients and waste around to and from cells Excretory system (kidneys, ureters, urethra, bladder)- Clean the blood of nitrogen or protwin waste Reproductive system (testes, ovaries) Make sperm and eggs, move those cells to the other organism Nervous/ muscular/ skeletal/ integumentary system (brain, sense organs, muscles, bones, skin)- Allow the organism to sense the environment and respond to it |

|
Crayfish organ systems |
Digestive system- Mouth: takes in food Esophagus: brings food to the stomach Two chambered stomach with teeth: grinds/ tears up food Digestive glands: absorb nutrients Intestine: remove waste from body
Circulatory system- Ostia: holes in the heart where the blood enters Open circulatory system: blood isn't always in the vessels
Excretory- Green glands: clean the blood of waste material Anus: where feces comes out
Nervous system- Brain: interpret the signals that come in and sends out the response signals Nerve cord: to carry messages from the brain Compound eye on stalks: to see Antennules: to taste, smell, touch, and balance Antennae: to taste, smell, and touch
Reproductive system- Testes and ovaries External fertilization: eggs go on the female's stomach and sperm is transferred to the eggs through the first swimmeret
Repiratory system- Gills: attached to the walking legs, allow crayfish to get oxygen from the water |
|
|
Frog organ systems |
Digestive system- Gullet leads to the stomach One chambered stomach breaks up the food Large and small intestine lead to the cloaca Helper organs produce chemicals that help break down the food; liver, gall bladder, and pancreas Circulatory- Closed circulatory system 3 chamber heart Excretory- Kidneys make the pee Ureters connect to the kidneys Bladder holds the pee Cloaca is where pee, poop, eggs, and sperm come out Respiratory- Lungs store the oxygen Glottis leads to the lungs Other Hear through the tympanum, eustacian tube leads to the tympanum |

Compare the organ systems. |
Digestive- Crayfish= 2 chambered stomach with teeth/ human and frog= 1 chambered stomach Frog= gullet leading to stomach/ crayfish and human= esophagus leading to stomach Crayfish have digestive glands Frogs and humans have large and small intestine/ crayfoah has one Circulatory- Frogs and humans= closed circulatory system/ crayfish= open circulatory system Frogs= 3 chamber heart/ humans= 4 chamber heart/ crayfish= 1 chamber heart Crayfish have ostia Respiratory- Frogs and humans have lungs/ crayfish have gills Humans have nostrils/ frogs have a glottis Excretory- Crayfish have green glands and an anus/ frogs have a cloaca/ humans have a urethra and an anus Reproductive- All have testes and ovaries Sperm comes out of swimmerets in crayfish Eggs and sperm come out of cloaca (same opening as urine and feces)
Nervous- Crayfish and humans have a spinal/ nervous cord All have brain Frogs have a nictitating membrane on their eye/ crayfish have compound eyes on stalks/ humans have eyes in their head Crayfish have antennae and antennules |
