READY-MADE CLASSROOM REVIEW
Ecosystems Review
Biology · Grades 6-8 · about 20 minutes. Project the board, share one room code, and keep the class on the same review.
Review before you host
Check the clues and answers for your group. Answers stay hidden during live play until the host reveals them.
Who Eats What?
$200An organism that makes its own food and begins most food chains has this role.
$400A rabbit that eats grasses belongs to this consumer group.
$600A hawk that eats mice belongs to this consumer group.
$800A bear that eats berries and fish belongs to this feeding group.
$1000A fungus fills this role by breaking down dead matter and returning nutrients to the environment.
Ecology Levels
$200One individual wolf represents this smallest ecological level.
$400All gray wolves living in Yellowstone at the same time form this group.
$600All the living populations interacting in one area form this ecological level.
$800A pond's organisms plus its water, soil, light, and temperature form this system.
$1000A large region defined by climate and characteristic life, such as tundra or desert, has this name.
Energy Pathways
$200This star supplies the energy that begins most food chains on Earth.
$400A single path showing who eats whom is called this.
$600Many connected feeding paths in a community form this diagram.
$800Producers and each successive consumer group occupy one of these feeding positions.
$1000This model narrows toward the top because less usable energy reaches each higher feeding level.
Species Relationships
$200Two plants seeking the same limited sunlight demonstrate this interaction.
$400A snake capturing and eating a mouse demonstrates this interaction.
$600Bees receive nectar while flowers receive pollination in this relationship where both species benefit.
$800A barnacle gains transportation on a whale while the whale is largely unaffected in this relationship.
$1000A tick gains nutrients while weakening its mammal host in this relationship.
Matter Cycles
$200Evaporation, condensation, and precipitation are major steps in this cycle.
$400Photosynthesis removes carbon dioxide from the atmosphere as part of this cycle.
$600Certain bacteria perform this process, changing atmospheric nitrogen into forms producers can use.
$800This producer process stores atmospheric carbon in sugars using light energy.
$1000This cell process releases carbon dioxide while transferring energy from glucose to ATP.
Ecosystems Change
$200The gradual replacement of one biological community by another is called this.
$400Lichens are often this early-arriving type of organism on newly exposed rock.
$600Water, food, space, or another resource that restricts population growth is called this.
$800The largest population an environment can support over time has this name.
$1000A nonnative organism that spreads and causes ecological harm is described by this term.
