Green algae (sing. alga) come in a heteromorph group of species and this is only a conventional name rather than biological classification. The group unites some predominant divisions like Chlorophyta and Charophyta.
Some species of Chlorophyta are considered to be the first ‘true’ plants by bridging between Protozoa and Plantae. Most of this division’s representatives are aquatic, they have chloroplasts and chlorophyll a and b, which are typical for plants. They could be unicellular, often colonial and even multicellular. The variety of the group is great in terms of their habitat, morpho-structure, reproductive system, etc. Some even live in symbiosis with fungi, but they are usually classified in a different division called Lichenophyta.
Explanation: Digestion begins in the mouth and continues throughout the GI track. Amylase is found in salIva and begins to break down maltose and dextrin in the mouth. You can also tell amylase is an enzyme because the suffix “-ase” refers to enzymes.
They ensured that balance in the ecosystem was maintained. They ensure that the genetic diversity and species is maintained. Sea otters applied natural selection pressures on the sea urchins population hence maintaining their level such that they will not overgraze on the kelps. Overgrazing would severely affect the sea urchin population and consequently severely affect the sea otters population too.
