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?)

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 |
