A mover loads a 100-kg box into the back of a moving truck by pushing it up a ramp. The ramp is 5m long and the back of the truck is 2 m high. What is the mechanical advantage of using the ramp?

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)

not too sure but maybe in the hot springs.
