Jane wants to test if strawberries that are kept cold will rot or stay edible. She places a strawberry in the refrigerator and records the date. What variable should be controlled?

I think it is the time or the degree of the cooling ability of the refrigerator

answer; /// i believe that the correct answer is (50%);

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)
