Heterospory, highly reduced gametophytes, ovules, pollen, seeds are the five adaptations common to all seed plants that ensure their success in the adaptation to land. Three things: The gametophytes of seed plants are reduced and dependent upon the parent sporophyte which protects them (particularly in the case of the female gametophyte). Pollen is covered with sporopollenin which is resistant to physical factors in the environment. The structure of the seed protects the next generation sporophyte and allows it to remain dormant until conditions are right for germination, development and growth.

Answer:
littoral zone
The littoral zone is rich in marine life. The bathyal zone is the part of the ocean floor that makes up the continental slope. It ranges from about 1,000 to 4,000 meters below sea level. The bathyal zone contains no producers because it is too far below the surface for sunlight to penetrate.

Explanation:
Ans.
<em>Viscum album </em>is a plant species, commonly known as mistletoe. It is a hemi-parasitic plant that grows on other trees.
Birds cause seed dispersal as they pick seeds from parent plant and drop them in other places. Seeds of mistletoe are sticky or viscous due to mucus and they provide nutritious food to the birds.
Hence, it can be concluded that the mistletoe seeds show adaptations primarily for seed dispersion, not for infecting the host plant.
Thus, the correct answer to be filled in the blank is 'is nutritious to the dispersing birds.'
