Ecosystem Levels
A single living individual within an ecosystem, such as a solitary deer or one bison.
What is an organism?
The symbiotic relationship where both participating organisms derive a survival or metabolic benefit, such as bees pollinating flowers or oxpeckers eating ticks off livestock.
What is mutualism?
Solar energy, atmospheric wind currents, and carbon dioxide gas
What are abiotic factors?
The explicit directional meaning of arrows drawn between organisms within an ecosystem food web model.
What is the flow of energy from food (prey) to the consumer (predator)?
My favorite sport.
What is Baseball?
This level of organization includes all the saguaro cacti living in a desert or a single herd of bison roaming a prairie.
What is a population?
The interaction demonstrated when Ustilago maydis fungal spores grow on sweet corn to siphon plant cell nutrients, or when tapeworms inhabit a jackrabbit.
What is parasitism?
Ecosystem inputs including bovine manure fertilizer, soil-aerating earthworms, and plant-pollinating honeybees.
What are biotic factors?
In a forest web containing grasshoppers, mice, owls, and foxes, this direct population trend is predicted for owls if grasshoppers and mice suddenly crash.
What is a population decrease?
My three favorite candies.
Starburst Jellybeans, Dark Chocolate, Tajin covered jelly beans.
A coastal environment where seagulls, crabs, and turtles all coexist and feed on the same seagrass beds.
What is a community?
An interaction where one species benefits without harming or helping the other, such as a spider spinning a web between plant stems or barnacles riding on a whale
What is commensalism?
An organismic interaction where a butterfly utilizes solar thermal radiation to dry its wings before flight.
What is an interaction between a biotic factor and an abiotic factor?
In a forest web featuring carrots, grasses, grains, rabbits, mice, and grasshoppers: if grasshopper and mice populations decrease, this happens to the carrot population because rabbits don't eat grasshoppers or mice.
What is remaining the same?
MyFavorite school supply.
Fun Pens - Flair or Frixon Clickable and Eraseable
The correct hierarchical arrangement of biological organization, ordered sequentially from simplest to most complex.
What is organism, population, community , ecosystem?
The relationship exhibited when cheetahs and lions target the same ungulate prey, or when hawks and snakes both hunt desert lizards
What is competition?
In a dense forest floor, a shade-tolerant fern competes directly against tall canopy trees for this primary abiotic energy resource.
What is sunlight (or solar energy)?
In a forest web featuring carrots, grasses, grains, rabbits, mice, and grasshoppers: if grasshoppers and mice decrease, the grass population will experience this change due to a loss of herbivores feeding on it.
What is an increase?
My three favorite places to shop.
What is Amazon, Academy, Costco.
A student claims that "all the saguaro cacti, the fennec foxes, and the rainfall in a desert make up a community". Identify the error in the student's reasoning and correct it.
What is: Communities consist only of interacting biotic populations; including rainfall introduces an abiotic factor, which turns the system into an ecosystem rather than a community?
While both interactions involve one organism extracting energy from another, predation typically results in rapid prey death, whereas this relationship relies on keeping the host alive over time.
What is parasitism?
In a garden with poor soil nutrients and severe drought, earthworms enhance soil structure, yet plant growth remains strictly limited because this non-living factor cannot be replaced.
What is an abiotic factor (water)?
In a desert food web where both hawks and rattlesnakes prey on lizards, and roadrunners prey on scorpions. If a disease wipes out the scorpion population, predict how the relationship between hawks and snakes will be affected.
What is: Roadrunners will switch to eating lizards, increasing competition among roadrunners, hawks, and snakes for the remaining lizard population?
This is my birthday.
What is May 7th?
