Inte­rac­tions in an Ecosys­tem

MUTUALISM
Mutualism is when both species benifit
Symbiosis
Shark + Remoras
PREDAT­ATION
Predat­ation is when one organism eats another
 
Owls + Mice
PARASITISM
Parasitism is one organism benifits and the other is harmed
Symbiosis
Covid + Humans
COMPET­ITION
Compet­ition is when one organism fights with another over something
 
Male birds fighting over a female
COMMEN­SALISM
Commen­salism is when one organism is benifits and the other is neither helped or harmed
Symbiosis
Birds + Trees
To earn even a bigger brain memorize which of these are symbiosis, define symbiosis and give and example of different organisms that fo through each of this things (You know what I mean don't you?)

SCIENCE 7 || UNIT 2

ADAP­TAT­IONS

BEHAVIORAL ADAPTA­TIONS
STRUCTUAL ADAPTA­TIONS
include activities / behaviors that help an animal survive
involves some physical charac­ter­istic (struc­ture) of an animal's body.
EXAMPLES
EXAMPLES
Migration (birds fly south in the winter), Hibern­ation (This is deep sleep in which animal’s body temp drops, body activities are slowed to conserve energy)
Mimicry (allows one animal to look, sound, act like another animal to fool predators into thinking it is poisonous or danger­ous.), Camoflauge (lets an animal blend in with it's enviro­ment)
Adapta­tions are inherited charac­ter­istic that helps an organism survive and reproduce in its enviro­nment

ECOL­OGICAL FOOTPR­INT

Everyday humans consume energy, materials & use land. The way you use the Earth leaves an impres­sion, like a footprint, of where you have been
Ecological footprint is the impact you have on the enviro­ment, the smaller your ecological footprint is, the better. Your ecological footprint is measured in Global Hectares (2 1/2 acres)
THE 4 R'S
Reduce
Cut down on/ limit the amount of garbage you use/shower (the bills??)
Reuse
Use again
Recycle
Turn something into a new thing
Recover
Waste being converted to energy
ITS IN THIS SPECIFIC ORDER: REDUCE, REUSE, RECYCLE, RECOVER

Food Web & Food Chains

FOOD CHAINS
FOOD WEBS
A pathway of energy flow from one living thing to another in an ecosystem
Link up of the many/ all of the possib­ilities of food chains in an ecosystem
Food chains always: start with the sun, show who eats who, energy flow moves in 1 direction, energy flows from the producer to the consumer
Food chains are not realistic as many organisms will eat more than one type of food and each organism will have more than one predator.
Food chains end with a decomposer who always return the nutrients back to the soil
There are producers and consumers in a food web

EXOSYSTEM VOCABULARY

Biotic Living or once living
Abiotic Never has lived
Symbiosis A relati­onship between 2 species that live closely together over a period of time
Ecosystem The intera­ctions between biotic and abiotic factors in an ares
Ecology The study of nature
Community Different groups of species live and interact with each other
Enviro­nment A place or location with abiotic factors
Population A group of induvi­duals of the same species living in an area
Niches The roles (jobs) of an organism
Producers Make their own food
Consumers Eat either consumers or producers
Carnivores Only eat meat (consu­mers)
Herbivores Eat producers only (plants)
Omnivore Eats both producers and consumers
Scavengers Eat dead and decaying plant and animal matter
Decomp­osers Break down dead organisms and return nutrients back to soil
Use these words in a sentence if you think your so smart
To help memorize, write the word and definition 10 times on a blank paper without looking at the previous sentences. Ex. Ecosystem are the intera­ctions between biotic and abiotic factors in an ares

The 4 basic needs of living things

Gas exchange - the plant take carbon dioxide and give us oxegyn that we turn into carbon dioxide that the plants turn into oxegyn...
Water
Energy
Suitable Habitat

Succesion

DEFINITION
EXAMPLE
SUCCESSION: A slow process where one species replaces another in an ecosystem
--
PIONEER SPECIES: The first species to occupy a lifeless piece of land
Lichen & Moss
PRIMARY SUCCESION: The gradual growth of a species in an area which nothing has lived there before
--
SECONDARY SUCCESION: Gradual growth of organisms in an area that used to be home to many species
--
BIOINV­ASION: Species are introduced to a location they have never been to before
A ship of fruit carries spiders with it that get sent to a new area
LIMITING FACTOR: Makes a population decrease in size
temper­ature, water availa­bility, oxygen, salinity, light, food and nutrients
THREATENED: The amount of a specific species is decreasing
Mountain Gorilla
ENDANGERED: Organism is in risk of being extinct
Spotted Owl
EXTIRPATED Organism is only lost in a large region
(Taylor) Swift Fox
EXTINCTION: Species is lost in the whole world
Wooly Mammoth

Toxins

Bioacc­umu­lation - the process in which toxins enter the food webs by building up in induvidual organisms
Toxins usually come via water
Biomag­nif­ication - rise or increase in contam­inated substances
Tuna, anyone?
