100
What is an ecosystem?
All living and nonliving things in an area.
100
What is a predator and prey relationship?
Predator eats the prey.
100
Give an example of a slow change in an environment.
Seasons, rocks breaking down, continental drifting, climate
100
What parts of the environment can pollution affect?
Air, water, and land
100
What is the shortest food chain?
Producer to decomposer
200
Describe this ecosystem. Coral reef
Shallow water, fish, warm water, coral
200
What is a producer?
Plants, they are able to make their own food
200
Give an example of a fast change to an environment.
Earthquake, tornado, tsunami, hurricane, forest fire
200
What is a nonnative species?
A plant or animal that does not grow naturally in an ecosystem.
200
What month are we in?
October
300
Describe this ecosystem. Tundra
Cold, animals have thick fur coats, high up in the mountains
300
What is a consumer?
An organism that cannot make their own food and must eat producers or other consumers.
300
How can organisms cause changes?
Locust bugs can eat all the crops in an area.
300
Why are nonnative species often times able to grow so quickly?
They do not have any predators to hunt them
300
What year did Mockingbird start?
1965
400
Describe this ecosystem. Desert
Dry, little rain, hot days, cool nights
400
What is a decomposer?
An organism that breaks down waste and dead organisms.
400
How can humans cause change in an environment?
Building houses, roads, and cities
400
What is conservation?
An attempt to preserve or protect an environment from harmful changes.
400
What year was Mrs. Stoffel born in?
1981
500
What is the balance in the ecosystem? Explain through discussion of hawks and mice populations.
When the hawk population is large, the mice population will go down due to eating so many. When the mice population gets too small, the hawk population will start to decrease due to lack of food. This will allow the mice population to start growing big again.
500
How do all food chains and food webs begin?
With a producer
500
What is competition?
The struggle of organisms for the same limited resources.
500
Why is conservation so important?
So we do not lose any environments or species.
500
How do a producer, consumer, and decomposer work together in an environment?
The producer produces food for other organisms. The consumer eats producers and other consumers allowing the populations to not get too large. The decomposer breaks down and gets rid of waste and dead organisms so they are not just lying around for millions of years.
