The muscle that inserts on the acromion and scapular spine is the Trapezius.
The trapezius muscle inserts into the scapular spine acromion and posterior superior lateral clavicle. Contraction of its various parts thus allows the scapula to be lifted, suspended, stabilized, and rotated. inserted. The deltoid muscle inserts into the acromion process, the main muscle that raises and extends the arm.

These muscles attach to the surface of the scapula and assist in the abduction and external and internal rotation of the glenohumeral joint.

Organisms adapt to their changing environment. When there is some pressure in the environment (for example, increased competition for food), then species with the most advantageous adaptations will survive. Because environments change pretty frequently, the organisms living there must cope with this change. This leads to ever changing and evolving species and increased biodiversity. Lastly, a high level of biodiversity leads to a healthy ecosystem because of the vast variety of organisms in that space. Many species allows niches to overlap and therefore no one organism occupies one niche.
Answer:
