Answer:
The sea star could be called a(n) keystone species.
Explanation:
The concept of keystone species was introduced by zoologist Robert T. Paine, in 1969. <u>A keystone species has a fundamental role in influencing an ecosystem, helping maintain the structure within an ecological community. The abundance or lack of the keystone species will determine the abundance or lack of other species as well.</u> It is common to use lions or wolves as examples of keystone species. If they disappear, certain animal populations that are usually hunted by them will prosper indiscriminately. That will drastically change the ecosystem, perhaps even leading it to its collapse. As we can see, the sea star describe in the passage is responsible for controlling the mussel population. The sea star is, therefore, a keystone species, preventing the overcrowding of mussels.
The family is the strongest pillar of any society. It is her responsibility to fulfill some missions such as protecting, educating and emotionally supporting her members. Over time, it may undergo some transformations, such as its dismemberment due to changes of city or even because of dissatisfaction in its structure.
The fact is that having a good family relationship allows us to enjoy one of the happiest aspects of our lives: contact with people we truly love. Likewise, these relationships can trigger conflicts, especially when there is authoritarianism and lack of reciprocity of good feelings. Maintaining good family relationships is the key to success in achieving inner peace.

Sequoyah (ᏍᏏᏉᏯ Ssiquoya, as he signed his name,[2][3] or ᏎᏉᏯ Se-quo-ya, as his name is often spelled today in Cherokee) (c.1770—1843), named in English George Gist or George Guess, was a Cherokee silversmith. In 1821 he completed his independent creation of a Cherokee syllabary, making reading and writing in Cherokee possible. This was one of the very few times in recorded history that a member of a pre-literate people created an original, effective writing system[1][4] (another example being Shong Lue Yang). After seeing its worth, the people of the Cherokee Nation rapidly began to use his syllabary and officially adopted it in 1825. Their literacy rate quickly surpassed that of surrounding European-American settlers.<span>[1]</span>
