|
|
|
10% rule
|
90% of energy is used for activities, keeping warm, moving, ect- stay alive and/or lost as heat. 10% is stored as biomass (body matter) for the next level to eat and break down and get energy out of
|
|
|
niche
|
an organism's role in it environment: who eats it, where it lives, its interrelationships, what eats it, and the effect it has on the ecosystem
|
|
|
Adaptations
|
Characteristics which organisms already have which allow them to survive
|
|
|
Diffusion
|
Molecules go from high to low concentration
|
|
|
Isotonic
|
Solute concentration outside is equal to the inside of the cell, nothing will happen
|
|
|
Hypertonic
|
Solute concentration outside is higher than the inside of the cell, the cell will shrink. Animal will crenate and die, Plant will plasmolyze and recover because of the cell wall
|
|
|
Hypotonic
|
Solute concentration outside is lower than the inside of the cell, the cell will swell. Animal will lysis (burst) and die, plant becomes turgid and recover.
|
|
|
Cell theory
|
1.Cell is the structural and functional unit of life.
2.All organisms are made up of cells or cell components. 3.Cells come from pre existing cells |
