ecosystems Flashcards
ecological niche
the role a species fulfils in an ecosystem
describe the three oxygen groups yk
aerobes (need oxygen)
anaerobes (survive without oxygen)
facultative anaerobes (can do both)
describe the ranges ig
optiumum is muy perfecto
stress is shit
intolerance es imposible
ingestion
provides the organism with the raw materials crucial for growth
digestion
changes the food into what acc can be like it breaks it down
absorption
allows the body to extract nutrients from the digested food and transport them to the cells for energy and shit
assimilation
like when the food becomes a part of the cell growth development and all
elimination
removing useless waste for the body to beable to funvtion properly
mixotrophs
both produce their own food and make their own ig depending on availability
like the plant that eats flies (venus flytrap)
facultative mixotroph
can switch between heterotroph and autotroph modes depending on the conditions and environment
obligate mixotroph
they need both autotrophic and heterotrophic modes to survive
what does a saprotroph do
they get energy by breaking down or oxidising chemical compounds
adaptations
changes in the body to fit a location
describe the saprotrops: bacteria
secrete enzymes that break down organic matter, breaking them down into small molecules which they later eat
describe the saprotroph: mold
produce enzymes that typically break down complex organic molecules
