FOOD CHAIN   show
🗑
FOOD WEB   show
🗑
OMNIVORE   show
🗑
show Starts with chemical energy stored in organic debris or waste from other food webs; energy flows from debris directly to decomposers that break down organic matter, which becomes food & energy for larger consumers, & then to decomposers; "DETRI-" = WEAR AWAY.  
🗑
show Organisms that transform energy from the Sun & use carbon dioxide & water to make food.  
🗑
show Organisms that feed on other organisms in a food chain.  
🗑
show Animals that only eat plants or plant products; "HERB-" = PLANT.  
🗑
show Animals that eat other animals; "CARN-" = MEAT.  
🗑
PRIMARY CONSUMERS   show
🗑
SECONDARY CONSUMERS   show
🗑
TERTIARY CONSUMERS   show
🗑
show Organisms such as bacteria and fungi that break down the remains of dead plants & animals, without need for internal digestion.  
🗑
show Any class of organisms occupying the same position in a food chain, such as primary consumers or secondary consumers; "TROPH-" = NOURISH.  
🗑
show Shows how much energy transfers to the next trophic level in a food chain.  
🗑
show System consisting of all of the interactions that occur between the abiotic & biotic factors within an environment; "ECO-" = NATURE.  
🗑
ENERGY TRANSFORMATION   show
🗑
CHEMICAL ENERGY   show
🗑
DIGESTION   show
🗑
show Sum of the potential & kinetic energy of an object.  
🗑
show Total kinetic (motion) energy of tiny particles that make up matter - the faster the particles move, the warmer the matter becomes.  
🗑
show Energy transferred between 2 objects of different temperatures, moving continually in a predictable pattern from warmer site to cooler site until all sites have reached the same temperature.  
🗑


   

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.
