|---|---|---|---|---|---|
| Carrying Capacity | The maximum population size that an environment can hold, without being affected by degradation of the habitat.
🗑
|
||||
| Cellular Respiration | A chemical process which allows an organism to utilize the energy stored in sugars to create ATP. It is performed by both animals and plants.
🗑
|
||||
| Chemical Equations | A symbolic representation of the process of converting energy into chemical energy. Can represent photosynthesis or cellular respiration.
🗑
|
||||
| Climax community | The final stage of ecological succession. It generally consists of organism populations finding relative stability with their environment.
🗑
|
||||
| commensalism | A relationship between two organisms, where at least one benefits from the relationship. The other is largely unaffected, or
🗑
|
||||
| consumer | An organism that obtains its energy by feeding on organic material, or other animals.
🗑
|
||||
| cyclic growth | The rise and fall of organism populations, based on interactions with other organisms. Easiest representation includes predator-prey relationships.
🗑
|
||||
| decomposer | Consumer of dead tissue matter. Include fungi, detritivores, and saprophytes.
🗑
|
||||
| Density dependent factors | Factors that limit the growth of populations. Density dependent are based on biotic factors. This includes competition, predation, and disease.
🗑
|
||||
| Density independent factors | Factors that limit the growth of populations. Density independent are based on abiotic factors, such as natural disasters.
🗑
|
||||
| ecological succession | A process where organisms begin to reinhabit an ecosystem, after a natural disturbance such as fire, or volcanic eruption.
🗑
|
||||
| energy flow | The distribution of energy in an ecosystem, whether by biotic or abiotic means.
🗑
|
||||
| exponential growth | A growth chart that steadily becomes larger every year. The human population is an example of exponential growth.
🗑
|
||||
| logistic growth | An S shaped growth chart, that grows slowly with less organisms, much faster with the more organisms, and slows down again once it hits the carrying capacity
🗑
|
||||
| mutualism | A relationship between two different types of organisms that generally benefit both parties.
🗑
|
||||
| parasitism | A non mutual relationship, where one organism benefits at the expense of the other.
🗑
|
||||
| photosynthesis | A process of converting solar energy into chemical energy. Only utilized by plants, or other organisms with chloroplasts.
🗑
|
||||
| pioneer species | The first organisms to inhabit a previously disrupted or damaged environment. This segways into ecological succession.
🗑
|
||||
| population | A group of one species that interbreed and live in the same area at the same time.
🗑
|
||||
| producer | An autotrophic organism that is capable of converting solar energy into organic compounds through photosynthesis.
🗑
|
||||
| products | A substance that is a result of a chemical equation.
🗑
|
||||
| pyramid of energy | A graphical representation to show the amount of biomass at each trophic level.
🗑
|
||||
| reactants | A substance that takes part in a chemical equation.
🗑
|
||||
| steady state | A dynamic equilibrium
🗑
|
||||
| symbiosis | A relationship between two organisms that are very interdependent. Can generally be beneficial for both 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.
