How many of the eggs actually hatch? A natural or in situ nest will have a hatching success rate of 80-100%, while a relocated nest will have a hatching success rate of 60-70%. Overall, only one in 1,000 to 10,000 sea turtles will live to maturity. Major predators after nest emergence include birds, fish, crabs, and foxes.
The Phaeophyceae or brown algae (singular: alga), is a large group of mostly marine multicellular algae, including many seaweeds of colder Northern Hemisphere waters.They play an important role in marine environments, both as food and for the habitats they form.he particular shade depends upon the amount of fucoxanthin present in the alga. Second, all brown algae are multicellular. There are no known species that exist as single cells or as colonies of cells, and the brown algae are the only major group of seaweeds that does not include such forms.
Thank you... Algae are simple, chlorophyll bearing and photosynthetic non vascular plants whose body is a simple thallus without differentiation into roots, stems and leaves. There are about 35000 species of algae.They include planktons, pond scums, stone worts, sea weeds, sea lettuce etc.Phycology is the branch in botany which deals with the study of algae.Characteristics of Algae. Body is a relatively simple simple unicellular or multicellular thallus, not differentiated into roots, stems and leaves. Unicellular thallus may be non motile, rhizopodial or coccoid.Multicellular thallus may be colonial, palmelloid, dendroid, filametous siphonous and so on. Algae cells exhibit three levels of organization, namely prokaryotic (eg: Myxophyceae), mesokaryotic (eg: Dinophyceae) and eukaryotic (other groups).here are about 35000 species of algae.They include planktons, pond scums, stone worts, sea weeds, sea lettuce etc. Phycology is the branch in botany which deals with the study of algae.
