|
living |
biotic, has at least one cell (basic unit of life) |
|
|
dead |
once living, now not living |
|
|
nonliving |
abiotic, never living |
|
|
6 characteristics |
organization, growth and development, reproduction, adaptation, response to a stimuli, energy |
|
|
organization |
allows for multitasking. all living things have structures that perform specific functions (divide and conquer) Ex cells and their organelles |
|
|
growth and development |
increase of size, complexity, and matter as cells produce/divide (mitosis). necessary for independence, survival, and reproduction |
|
|
reproduction |
sexual or asexual, for survival of species, formation of offspring, not important for individual survival (not everyone needs to reproduce) |
|
|
species |
a group of organisms that can interbreed and have fertile offspring |
|
|
fertile |
offspring can have offspring |
|
|
sterile |
cannot reproduce |
|
|
adatation |
any characteristic in DNA that increases the survival of an organism in its environment |
|
|
variation |
natural differences of a trait in a group of organisms eg hair color, skin color, size |
|
|
response to stimulus |
ability to respond to a stimulus quickly and appropriately to survive |
|
|
stimulus |
changes in external or internal environmen |
|
|
homeostasis |
maintain a constant stable internal environment |
|
|
positive feedback loop |
response to change strengthens until tipping point eg blood clot, childbirth graph is a straight line |
|
|
negative feedback loop |
response counteracts change in condition graph is a full loop eg sweating, shivering |
|
|
energy |
all living things require energy because it fuels all other characteristics |
|
|
animals |
heterotrophs/consumers eat food |
|
|
plants |
autotrophs/producers get energy by producing nutrients aka photosynthesis |
|
|
fungi |
heterotrophs/decomposers get energy from decomposing dead matter |
|
|
protists/bacteria |
depending on organism, they can eat, produce, or decompose to gain energy |
