How did life invade the land? How did life move on from being only in water. Organisms on land must face the force of gravity. Organisms in the sea have support against gravity. On land, organisms must ensure that their gametes do not dry out in reproduction. There would be certain benefits for the organisms to move to land.
One benefits for land are rich storehouses of nutrients in terrestrial soils. Seawater is low in certain nutrients like nitrogen and phosphorus. Another benefit is the sunlight. It provides enough light for rapid photosynthesis. Another benefit is the lack of land predators. In the sea, there are plant-eating animals. On land, the plants would have a lot of sunlight, no predators, and untouched nutrient sources.
