The Rhodophyta algae Porphyra is known to colonize aquatic environments deeper than the Chlorophyta algae Spirogyra; why is this and what advantages does Porphyra have by claiming this niche?
Homework Answers
Spirogyra ( Chlorophyta) and Porphyra ( rhodophyta) vary in occupancy of niche in ocean whereas spirogyra occupies surface, the porphyra occupies deeper oceans.
For the surface àlgae sufficient light is presence for photosynthesis to occur. The red yellow wavelengths are utilized by surface algae for photosynthesis. These wavelengths cannot reach deeper oceans. But blue light can reach deeper oceans which can be easily absorbed by porphyra to carry photosynthesis.
So variation in niche allows to use sunlight resource differentially.

If humans had evolved to live in an aquatic freshwater environment rather than evolving to live in terrestrial environments, what evolutionary adaptions would be necessary to maintain water and salt balances, and how would the osmoregulatory and excretory systems have to change? Write a brief description of the osmoregulatory and excretory systems of a human that adapted for an aquatic freshwater environment, and why it would look the way it does. Consider the following: What would be required to maintain...
