| Question | Answer |
|---|---|
| the ultimate source of energy for life on earth | sun |
| aka producer ; make their own food | autotroph |
| aka consumer ; must eat their food | heterotroph |
| consumer that eats both plants and meat | omnivore |
| consumer that eats only meat | carnivore |
| consumer that eats only plants | herbivore |
| organism that breaks down dead organic matter ex. bacteria | decomposer |
| consumer that eats dead material ex. vulture | scavenger |
| says that only 10% of available energy goes to the next higher trophic level | Rule of 10 |
| says that pollution and toxins INCREASE as you move up an ecological pyramid | biomagnification |
| any living thing | organism |
| means living tissue | biomass |
| planet Earth ; where life exists | biosphere |
| many members of the same species in the same area | population |
| a diagram of one way feeding pattern | food chain |
| a complex diagram of many feeding patterns in an ecosystem | food web |
| plants converting sunlight energy into usable chemical energy | photosynthesis |
| plants converting chemical energy into useable chemical energy | chemosynthesis |
| this happens to 90% of energy at each trophic level | used for growth and lost as heat |
| both cause population to increase | births and immigration |
| both cause population to decrease | deaths and emigration |
| density factors that affect all populations the same | density-independent factors |
| density factors that affect larger populations | density-dependent factors |
