According to Garrett Hardin, what is "the tragedy of the commons"? A. If everyone believes the same thing, there will be no new ideas
from which people can learn and grow.
B. Poorer nations will not grow and prosper if the rich continue to
take property and wealth from them.
C. A country that doesn't allow its citizens to rule themselves will
often fail and fall into chaos and disarray.
D. In a system of voluntary restriction, if one person takes more than
his or her share, it will ruin the system for everyone.

we would need to see the picture to answer it

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)

substitution is the answer in this case
