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
