---|---|---|---|---|---|
food chain | A single, linear path showing the flow of energy from the sun to producers and through different levels of consumers.
🗑
|

food web | Overlapping food chains with different pathways for the flow of food energy in the same ecosystem.
🗑
|
||||
trophic level | The position an organism occupies in the food web.
🗑
|
||||
producer | An organism that makes complex, energy-containing biomolecules from simple inorganic molecules using energy captured from light OR inorganic chemical compounds.
🗑
|
||||
consumer | An organism that must ingest other organisms for nutrients.
🗑
|
||||
herbivore | An organism that consumes only plants to get energy
🗑
|
||||
carnivore | An animal that eats other animals to get energy.
🗑
|
||||
omnivore | An organism that consumes both animals and plants to get energy.
🗑
|
||||
parasite | An organism that survives on a host organism and causes harm to the host.
🗑
|
||||
host | An organism upon or within which another organism lives.
🗑
|

freshwater ecosystem | An ecosystem found in streams, lakes, and rivers where the water has less than 1% salt content.
🗑
|
||||
autotroph | An organism that obtains its nutrition from simple, inorganic compounds.
🗑
|

heterotroph | An organism that must use other organisms for food, such as animals.
🗑
|
||||
energy pyramid | A diagram that shows the trophic levels of organisms in a food web.
🗑
|
||||
decomposer | An organism such as bacteria and fungi that breaks down the remains of dead organisms without need for internal digestion.
🗑
|
||||
scavenger | An organism that eats dead and decaying organisms and uses internal digestion to get the energy. (carnivores, many insects, some birds, many sea creatures)
🗑
|
||||
organic molecules | A large class of gaseous, liquid, or solid chemical compounds whose molecules contain carbon, and in addition to carbon: H, O, N, P, S
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
