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.


Prairie- big bluestem/ goldenrod/ quails/ indian grass/ mice/ etc


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


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


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


Closed circulatory system

3 chamber heart


Kidneys make the pee

Ureters connect to the kidneys

Bladder holds the pee

Cloaca is where pee, poop, eggs, and sperm come out


Lungs store the oxygen

Glottis leads to the lungs


Hear through the tympanum, eustacian tube leads to the tympanum

Compare the organ systems.


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


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


Frogs and humans have lungs/ crayfish have gills

Humans have nostrils/ frogs have a glottis


Crayfish have green glands and an anus/ frogs have a cloaca/ humans have a urethra and an anus


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)


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
