Changes to an Ecosystem
100
Any living thing
What is an organism
100
The trophic level plants are a part of.
What are producers?
100
What is the smallest group in an ecosystem
What is an individual (one organism)
100
This is the direction the arrow points to show a feeding relationship between 2 organisms.
What is, the arrow points to the organism getting the energy?
100
This is the effect on the secondary consumer populations (increase or decrease), if the coyote population decreases. Mono Lake Ecosystem
What is, the secondary consumers will increase because there are less coyotes to prey on them.
200
Which is nonliving? A squirrel, two raccoons, a snake, a rock, a palm tree
What is a rock
200
These are organisms that eat other organisms.
What are consumers?
200
Describe a population
What is all of one kind of a species that lives in an ecosystem
200
This is the feeding relationship between the eagle and the beaver.
What is, the eagle gets energy by eating the beaver? or, the beaver gives energy to the eagle.
200
These are 2 organisms that get energy directly from producers in the Mono Lake ecosystem.
What are brine shrimp and brine flies?
300
Which of the following is an example of a living thing: a feather, water, a beetle, rocks, a waterfall
What is a beetle
300
These are 2 secondary consumers from any of the food webs we have studied.
What are frog and trout, California gull and eared grebe, sea star and crab, other reasonable answers
300
Describe some of the species that would make up the community of Yellowstone National Park.
What are elk, hawk, bear, wolves, trout, willows, grasses, aspen, beaver, etc.
300
This is the feeding relationship between the sea star and the kelp in the Monterey Bay ecosystem.
What is, the kelp gives energy to the sea urchin which gives energy to the sea star kelp > sea urchin > sea star
300
This is the effect on the willow plant (increase or decrease), if the wolf population increases in Yellowstone National Park.
What is, the willow plant population will increase because there will be less elk overgrazing.
400
Three examples of abiotic factors.
What are lightning, air, water, temperature, wind, sunlight, clouds, rain, rocks, etc.
400
Organisms in this trophic level break down dead matter and return nutrients to the soil.
What are decomposers?
400
Describe the difference between a community and an ecosystem.
What is a community is all the living things (plants and animals). An ecosystem includes all the living and nonliving things.
400
This is the reason the otter, urchin, and kelp populations flatten out and remain constant from 2000 to 2016 in the graph.
What is, the otter, urchin, and kelp populations reached equilibrium (balance with each other)?
400
This is the relationship between the otter population and the kelp population in the Monterey Bay ecosystem. Use the graph and food web as resources.
What is, as the otter population increase, the kelp population increases also because there are less urchins feeding on the kelp.
500
In order to survive, all living things need:
What is space, shelter, air (oxygen), food, and water
500
This is an example food chain with one organism from each trophic level.
What is kelp--> urchin--> sea star--> otter =>bacteria algae--> brine shrimp--> eared grebe--> coyote > bacteria other possible answers
500
Describe an ecosystem
What is an area of land and all the living and nonliving things that interact within it.
500
This is a complete food chain in the Monterey Bay food web.
What is, * kelp > small fish > sea star > otter * answers will vary
500
This is the effect on a population in the Arctic ecosystem as global temperatures rise (climate change).
What is, * the polar bears decrease because there is less ice for them to hunt well. * answers may vary
