The ocean is a three-dimensional environment and this allows it to be the environment with the greatest biodiversity in the world, because it allows different organisms to be able to live at different depths and related environmental factors.
With that, we can affirm that in the ocean there is life that would only be able to stay alive in shallower waters, however the bottom of the ocean is rich in diversity of animal and plant life, unknown even to human beings.
An international team of developers created a 3 dimensional map to study the extremely diverse environment of marine life. The map is intended for conservationists, biologists, government officials, and others who make better decisions about ocean preservation and the many endangered species that live in the ocean
Since there are millions of species that survive in different depths of the ocean, the map can offer up information about why marine animals choose to live in a specific location. Scientists will better be able to study the interaction between warm and cold waters, or oxygen-rich and oxygen-poor regions.
It is commensalism because commensalism is a relationship that exist between two organisms in which one organism benefit and the other organism neither benefit and it is not harmed.
The egret obtain accomodation and feed on flying insects at the mouth of the herbivore and the herbivore dies not benefit anything or not harmed. The herbivore us not harmed by the presence of the insects.
This phenomenon is called bottleneck effect and drastically affects small populations in comparison to large ones. The mudslide wipes off most of the population B at the base of the hill base. Due to their small population, a large proportion of the population is lost and the pollution loses most of its alleles leaving a small proportion to continue the population succession. Its diversity is hence reduced as it repopulates. The larger population is not greatly affected because it covers much of the hillside.
