Body enclosed in a shell consisting of two valves, hinged dorsally; no head or radula; wedge-shaped foot. Marine and freshwater. Anodonta, Mytilus, Venus. Approximately 300,000 species.

# data[].attributes.body
Foot modified into a circle of tentacles and a siphon; shell reduced or absent; head in line with the elongate visceral mass. Marine. Octopus, Loligo, Sepia, Nautilus.

# data[].attributes.body
Shell, when present, usually coiled; body symmetry distorted by torsion; some monoecious species. Marine, freshwater, terrestrial. Nerita, Orthaliculus, Helix. More than 35,000 species.

# data[].attributes.body
A larval stage characteristic of certain mollusks, as well as other invertebrates, featuring a ciliated, free-swimming body.

# data[].attributes.body
The central part of a mollusk's body that contains the internal organs.

# data[].attributes.body
A fold of tissue in mollusks that secretes the shell (when present) and encloses the mantle cavity.

# data[].attributes.body
A developmental process in gastropods where the visceral mass undergoes a 180-degree rotation, bringing the mantle cavity and anus over the head.

# data[].attributes.body
The space between the mantle and the body of a mollusk, housing the gills, reproductive organs, and excretory system.

# data[].attributes.body
A rasping, tongue-like organ found in most mollusks except bivalves, used for scraping food particles off surfaces.

# data[].attributes.body
A mass of nerve cells, particularly one that serves as a center of nervous coordination in invertebrates like mollusks.

# data[].attributes.body
A structure in bivalves that expels water from the mantle cavity after it has passed through the gills.

# data[].attributes.body
A structure in bivalves that directs water into the mantle cavity for filter feeding and respiration.

# data[].attributes.body
The primary body cavity of most invertebrates, filled with hemolymph.

# data[].attributes.body
The circulatory fluid of invertebrates, analogous to blood in vertebrates, found in open circulatory systems.

the cycle through which carbon is exchanged among the atmosphere, oceans, soil, and living organisms.Nitrogen Cycle:

# data[].attributes.body
The carbon cycle involves the movement of carbon atoms between the atmosphere, plants, animals, and the soil.

# data[].attributes.attachment_caption
The cycle of processes by which nitrogen is converted between its various chemical forms in the environment.

# data[].attributes.body
Bacteria play a crucial role in the nitrogen cycle by converting nitrogen gas into forms usable by plants.

# data[].attributes.attachment_caption
The movement of phosphorus through the lithosphere, hydrosphere, and biosphere.

# data[].attributes.body
The phosphorous cycle is essential for the transfer of this vital element between rocks, soil, and living organisms.

The process by which the structure of a biological community evolves over time.

# data[].attributes.body
Ecological succession in a recently burned forest involves the gradual establishment of new plant and animal communities.

# data[].attributes.attachment_caption
the process of ecological succession that occurs in an area where no soil initially exists.

# data[].attributes.body
Mosses and lichens are pioneers in primary succession, colonizing barren landscapes and initiating soil formation.

# data[].attributes.attachment_caption
The process of ecological succession that occurs in an area where the existing community has been disturbed.

# data[].attributes.body
After a forest fire, secondary succession occurs as new vegetation grows in the previously established ecosystem.

# data[].attributes.attachment_caption
The first species to colonize an area in the early stages of ecological succession.

# data[].attributes.body
Lichens are often pioneer species, paving the way for more complex plant communities in ecological succession.

# data[].attributes.attachment_caption
A stable and mature community that undergoes little or no change in species composition over time.

# data[].attributes.body
Over time, a mature and stable climax community develops, representing the peak of ecological succession in an area.
