The energy level at which an organism isfeeding at in a food chain
Only 10% of energy gets passed to thenext level
<--energy gets lost through

A food web is many interconnected foodchains
needs to stay in balance to staysustainable. invasive species can putpressure on that
habitat
Carrying capacity maximum populationsize that can sustain indefinitely in anenvironment. Given the food, habitat andwater
Ecological niche
Bioaccumilation &biomagnification
Bioaccumilation
The ingestion of toxins within an organismat a rate faster than they are eliminated
Biomagnification
Concentration of a toxin magnifies as itgoes through the food chain
Biotic & Abiotic
Abiotic: non-living physical and chemicalcomponents of ecosystem
Biotic: the living components of an ecosystem including relationships and products
Biotic relationships
Symbiosis
Mutualism
Commensalism
Parasitism
Predation
Population
Community
Competition
Abiotic
Invasive Species
Any organism that is not native to anecosystem and causes harm to thatecosystem
Some examples in Ontario includethe purple loosestrife, garlicmustard, buckthorns, emerald ashborer, zebra mussels, dogstrangling vine and reed canarygrass
food webwhen invasive species enter aforeign food chain they can have a seriousimpact. since the species has no naturalpredators they will become overpopulatedan start to eat and over-consume thewildlife of the food chain causing a trickledown effect that could completely destroythe web
Photosythesis andcellular respiration
They are opposite operations
Photosynthesis
a process in which the plant turnssolar energy to chemical energy
the product of photosynthesis is what isused for cellular respiration
Chloroplast cell organelle. contains...
chlorophyll green pigment
only in daytime due to sun
Cellular respiration
a process which releases energy fromcarbohydrates in the form of oxygen
mitochondria the powerhouse of the cell,where energy is produced (respiration)
day and night because cellular respirationdoes not rely on the sun
the product of cellular respiration is what isused in photosynthesis
