|---|---|---|---|---|---|
| Give two names for organisms that make their own food in an ecosystem | show 🗑
|
||||
| show | autotrophs
🗑
|
||||
| show | one group does photosynthesis ( photoautotrophs).. they have chlorophyll that absorbs energy from light and convert carbon dioxide and water to glucose ( which provides food).. the other group of autotrophs are are chemoautotrophs(later)
🗑
|
||||
| Describe chemoautotrophs or autotrophs that do chemosynthesis ( how do they get energy and where do they live) | show 🗑
|
||||
| show | autotrophs ( photoautotrophs) autotrophs that do photosynthesis
🗑
|
||||
| show | autotrophs ( chemoautotrophs) autotrophs that do chemosynthesis
🗑
|
||||
| show | heterotrophs also called consumers
🗑
|
||||
| show | herbivores they are also primary consumers
🗑
|
||||
| cows, rabbits, or grasshoppers are called ? in a food chain | show 🗑
|
||||
| show | carnivores
🗑
|
||||
| A lynx consuming an arctic hare is a/an | show 🗑
|
||||
| show | omnivores
🗑
|
||||
| fungi that obtain food energy from a dead log recycle materials in dead organisms are are called | show 🗑
|
||||
| Name two very important types of decomposers | show 🗑
|
||||
| A human is A. a herbivore B. an omnivore C a carnivore or D a decomposer | show 🗑
|
||||
| show | detritivores
🗑
|
||||
| show | worms, aquatic insects ( a few that we know live in estuaries.. crabs, oysters, crayfish)
🗑
|
||||
| Which organisms BREAK DOWN DEAD ORGANISMS BY RELEASING DIGESTIVE ENZYMES... | show 🗑
|
||||
| show | decomposition , they break down its body into organic compounds... it is primarily the decompowers that make the nutrients available to producers for reuse..
🗑
|
||||
| Name two models of energy flow... | show 🗑
|
||||
| Each step of a food chain or food web is called a/an | show 🗑
|
||||
| What makes up the first trophic level in all ecosystems | show 🗑
|
||||
| How do organisms at the first trophic level get their energy | show 🗑
|
||||
| where do organisms at each trophic level( except the first) get their energy ? | show 🗑
|
||||
| what is a simplified model showing the transfer of energy from organism to organism | show 🗑
|
||||
| On a food chain, what represents the one- way energy flow that typically starts with an autotroph and moves to heterotrophs | show 🗑
|
||||
| show | each organism uses a portion of the energy for cellular processes ( building new cells etc).. the remaining energy is released into the surrounding environment and is not longer available ( lost as heat)..
🗑
|
||||
| show | food web. feeding relationships are more complex. most organisms feed on more than one species.
🗑
|
||||
| show | food web
🗑
|
||||
| What model of energy flowing through an ecosystem looks like a triangle ... it also looks like something in egypt | show 🗑
|
||||
| show | pyramid of energy, pyramid of biomass, and pyramid of numbers
🗑
|
||||
| ecological pyramids show ____ at each level ... they show the various ______ levels | show 🗑
|
||||
| what is the general trend in energy, biomass, and numbers going from autotrophs to 2nd level consumers... or 3rd level consumers | show 🗑
|
||||
| show | 90%... most of the energy contained in the organisms at each level is consumed by cellular processes or released into the environment as heat
🗑

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.
