Seeds that are transported by wind or water typically are
a. dispersed by animals.
b. lightweight.
c. large.
d. sweet and fleshy.

Option B, lightweight

Explanation:

Wind basically carries away the seeds which are light weight and winged which makes them peculiar to fit in the criteria required for floating. For example seeds of swan plants and cotton wood are light weight and also have some feather like bristles which allow them to be carried away by wind to a longer distance.

Water also carries light weight seeds as they can easily float on the water  for example seeds of mangrove trees.  

Thus, Option B is the correct answer

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)
