Why are there so many jellyfish in our rivers? A Case
... Major Theories for Increased Jellyfish Blooms (Taken from the Barnegat Bay Partnership) 1. The “hardening” of shorelines throughout the bay (e.g., bulkheads, pilings, docks) provides habitat for jellyfish “polyps.” Each jellyfish polyp buds off many baby jellyfish. 2. Changes in the salinity in the ...

Habitat
.JPG?width=300)
A habitat is an ecological or environmental area that is inhabited by human, a particular species of animal, plant, or other type of organism.A place where a living thing lives is its habitat. It is a place where it can find food, shelter, protection and mates for reproduction. It is the natural environment in which an organism lives, or the physical environment that surrounds a species population.A habitat is made up of physical factors such as soil, moisture, range of temperature, and availability of light as well as biotic factors such as the availability of food and the presence of predators. A habitat is not necessarily a geographic area—for a parasitic organism it is the body of its host, part of the host's body such as the digestive tract, or a cell within the host's body.
