Ecosystems/Roles
These organism roles make their own food using energy from the sun, water, and carbon dioxide.
What are "producers"?
Arrows represent this in a food chain.
What is "energy"?
A natural disaster occurs naturally, devastating certain ecosystems. This is caused by humans.
What is "pollution"?
No organism of this population exists anymore.
What is "extinct"?
This organism role eat other organisms.
What are "consumers"?
What is "the sun"?
An oil spill happens in an ocean, killing off a population of otters. The otters used to eat sea urchins. The sea urchins eat kelp beds.This organism's population will increase.
What are "sea urchins"?
A low number of these organisms exist.
What is "scarce"?
These organism roles break down dead organisms and provide nutrients for plants to grow.
What are "decomposers"?
Arrows point towards an organism doing this.
What is "consuming" or "eating"?
Seals are hit with a disease. They used to eat fish and were eaten by polar bears. This organism will also be negatively impacted by the loss of seals.
What are "polar bears"?
Too many organisms of this population exist.
What is "over-abundant"?
Forests, oceans, lakes, deserts, etc. are all examples of this.
What gets its energy from both producers and consumers?
What are "decomposers"?
There is a lake ecosystem. Fish eat algae and bears eat the fish. The lake waters flood the town. This organism would not be able to survive this natural disaster.
What is "the bear"?
Rabbits become scarce. Snakes rely heavily on rabbits for food. Rabbits consume a lot of grass. The population of the grass may become this.
What is "over-abundant"?
This is a living thing that lives in an ecosystem.
What is "organism"?
In a food web, a lion has arrows pointing to it from a giraffe and rhino, but no arrows pointed away from it. The lion is this of the flow of energy.
What is "the end" of the flow of energy?
A fire occurs on land. What kind of ecosystem would experience the least amount of impact.
What is a "water ecosystem"?
There is a disease that spreads amongst squirrels. Squirrels eat tree nuts. Owls eat squirrels. The owl population may become this.
What is "scarce"?
