Fibrous joints are mainly three types called sutures, gomphosis and syndesmosis.

Suture is one of the fibrous tissue which only present in skull called cranal suture. There is tiny amount of movement present it sutures for elasticity of skull.

Gomphosis:

Gomphosis is found in the tooth which bind tooth with tooth socket bone by periodontal ligament. This joint is completely immovable.

<h3>Compensatory strategy for improving independence with self-feeding</h3>

Explanation:

Limitation of shoulder or elbow range of motion due to fracture, dislocation or an injury like a burn injury will lead to flexion contracture.

This limits the patient’s ability to flex or extend the elbows freely to perform activities of daily living (ADL) like self-feeding, self-grooming etc.

Such patients should be assisted with supportive compensatory strategies to and improve their independence by aiding them perform their own ADLs.

Appropriate positioning of the patient and adjusting the height of the food table while eating, trunk swaying, tabletop propping, elbow orthoses like custom-cuffs, dynamic elbow orthoses, feeding utensils with customized handles to hold, robotic arm, and other mechanized orthoses can be utilized to improve independence with self-feeding.

A raft by design cannot withstand much load because of it's size or can only accommodate  only one type of organism at a time but an ecosystem generally accommodates a community (different organisms), hence the carrying capacity of an ecosystem is way larger than that of a raft and indeed a raft can be part of an ecosystem at some point
