I think in this case Bryophytes are more similar to ancestral green algae than are vascular plants. These plants lack a vascular system for transporting water and minerals, Unlike angiosperms they do not produce flowers, fruits, or seeds. They also lack true leaves, roots, and . stems, They appear as small, green mats of vegetation found i damp habitats. Lack of vascular tissues means that these plants must remain in moist environments.
Answer:
Ecological tolerance refers to the ability of an organism, or animal to be able to adapt and survive changing environmental conditions.
The combination of factors that would result in an island community with the lowest ecological tolerance would be option B Introduction of invasive species, increased deforestation because with the introduction of invasive species, there would be more competition for natural resources such as food, water, sunlight; and with increased deforestation, there is greater chances of soil erosion.

Insular biogeography or island biogeography is a field within biogeography that examines the factors that affect the species richness and diversification of isolated natural communities. The theory was originally developed to explain the pattern of the species–area relationship occurring in oceanic islands.
The reptile population decreases as arthropods decrease with their habitat
Migrating species are more likely to find larger habitats over smaller ones. Explanation: The concept of island biogeographical model establishes that larger islands and habitats will have a larger number of species than a smaller island. Larger islands have more tendency to attract new species.The species–area relation, whereby the number of species in a spatial unit increases with that unit’s area, well predates the MacArthur and Wilson theory of island biogeography, having been documented for about 150 years. Two general kinds of models for this relation have been proposed. The first has number of species predicted from an assumed species–abundance distribution and the total number of individuals of all species combined (assumed proportional to area). The second develops species–area relations from MacArthur and Wilson’s species-equilibrium approach.
<span>There are three primary systems in the body that act as a buffer, in order to help maintain pH stability.
The first is known as the phosphate buffer, which neutralizes excess hydroxide ions as they enter cellular fluid.
The second is called the protein buffer, and maintains acidity in the body. The hemoglobin in blood, which binds to acids in the bloodstream, is one such example of this system.
The third system is called the carbonic acid bicarbonate buffer, which neutralizes the acids generated by various metabolic processes, such as digestion and respiration.</span>
