Question
Answer
Carrying Capacity   The limit of organisms that an ecosystem can support.  
🗑
Cellular Respiration   The process that uses energy from sugars to create ATP (energy used by cells)  
🗑
Chemical Equations   A symbolic representation of a chemical reaction  
🗑
Climax Community   The apex stage of succession  
🗑
Commensalism   A relationship between organisms that benefits one and doesn't harm or benefit the other  
🗑
Consumer   An organism that cannot produce its own food and therefore eats other organisms  
🗑
Cyclic Growth   Growth occurs when there is a low amount of population, food is very high, so the population explodes.  
🗑
Decomposer   An organism that feeds and gains energy by breaking down dead matter  
🗑
Density dependant Factors   Biotic factors that affects population according to population density  
🗑
Density independent Factors   Abiotic factors that affect population regardless of population density  
🗑
Ecological Succession   Gradual replacement of communities over time  
🗑
Energy Flow   How energy transfers through a food web or chain  
🗑
Exponential Growth   Growth of a population that increases in a similar way to compound interest  
🗑
Logistic Growth   The point where a population reaches the carrying capacity of the ecosystem  
🗑
Mutualism   A relationship between two organisms that benefits both  
🗑
Parasitism   A relationship between two organism that benefits one and harms the other  
🗑
Photosynthesis   The process that plants use to convert light energy, carbon dioxide and water to make sugars and oxygen  
🗑
Pioneer Species   The first organisms in primary succession to settle in an ecosystem  
🗑
Population   A group of a single species in a ecosystem  
🗑
Producer   An organism capable of making its own food and energy  
🗑
Products   A substance that forms after a reaction  
🗑
Pyramid of Energy   A model used to describe the way energy is lost as heat when a creature gains energy  
🗑
Reactants   Substances used to make a reaction  
🗑
Steady State   An equilibrium of populations  
🗑
Symbiosis   Relationships had between organisms  
🗑


   

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.
