The first organisms to invade land were likely non-vascular plants, such as mosses and liverworts, which appeared approximately 470 million years ago during the Ordovician period. These early land plants were crucial for stabilizing soil and paving the way for other life forms. They adapted to terrestrial conditions by developing structures to absorb water and nutrients, ultimately leading to the diversification of life on land.
Bacteria that invade a host organism and obtain nutrients from the host's cell are pathegonic bacteria.
Antigens: BUT that is only true if the antigens cause a harmful reaction when they invade.
A terrestrial organism is an organism that predominantly lives on land. Examples of terrestrial organisms are dogs, cows, wolves and ants.
I believe you are asking what the first word of an organism's scientific name is. If that is the case, the first word in an organism's scientific name is the organism's taxonomic genus.
The first plant group to successfully invade land was the bryophytes, which include mosses, liverworts, and hornworts. These non-vascular plants adapted to terrestrial environments by developing structures for water retention and reproduction that did not rely on water for fertilization. Their ability to thrive in moist environments paved the way for more complex plant groups to eventually colonize land.
Most evolutionary biologists theorize that the first living organisms were single-celled prokariotes similar to currently existing bacteria. The distinction between proto-biotic and true life is a difficult one, so while there were self-replicating amino acid chains, the first life would have been a distinct cell that divided in an aqueous (watery) environment.

The first animals to enter land were the invertebrates, followed by some fish which later evolved into amphibians.

First were the plants and fungi, then came the arthropods, then finally the vertebrates.
Nonvascular plants
Tamerlane invaded India, but he wasn't the first to invade. The first person to invade India was Shun Johan. So Shun Johan was the first to invade India.
It is Pathogenic
the first invaders ever to invade rome was the huns!!
Since we don't actually know which organism appeared first, there's no way of knowing what came second.
The first animals to successfully invade land were likely arthropods, such as early ancestors of insects, spiders, and scorpions. These creatures adapted to terrestrial environments by developing structures like jointed legs and exoskeletons to support themselves outside of water. They played a crucial role in the colonization of land and paving the way for subsequent terrestrial animal life.
Plants were because all they needed was water and sunlight. Which they had...
