What are the Organisms in This Feeding Frenzy?

NGSS Phenomena: a time-lapse of many different sea creatures eating a dead tuna fish.
In the image above, we see a time lapse of several different types of living things eating a dead tuna fish on the ocean floor.

1. If there were more dead fish, we would expect competition to and if there were less fish that die in this ecosystem, we would expect competition to .

Drag the answers below into the grey placeholders above

stay the same
increase
decrease

2. The living things eating the tuna we see here are in the ecosystem

Drag the answers below into the grey placeholders above

scavengers
predators
producers

3. What do you predict would happen to the populations of these organisms if more fish started dying than normal?

4. The relationship between each of different the organisms eating the tuna is .

Drag the answers below into the grey placeholders above

predatory
competitive
mutually beneficial

5. Write a claim that answers the following question:

What role does competition play in this ecosystem?

6. What evidence can help support your claim that answers the question?

What role does competition play in this ecosystem?

7. What reasoning can you use to explain how your evidence and claim answer this question?

What role does competition play in this ecosystem?

8. One of your classmates makes the following claim:

"There isn't any competition between the organisms eating the tuna, because there is plenty of fish for each of them to eat. Tuna are large animals and these are all much smaller."

Evaluate their statement and make sure you give evidence to support your thoughts.

9. Use an example from the ecosystem where you live to demonstrate how this same pattern of interactions might take place between different animals in your ecosystem. Be sure to reference the data provided and support your response with at least two pieces of evidence.
