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.
Answer:
Hypothetico-deductive model
Explanation:
Hypothetico-deductive model consists of taking some assertions as hypotheses and testing such hypotheses by deducing from them, together with the knowledge that we already have, conclusions that we confront with the facts.This model is applied to obtain predictions from a theory. If the assumptions are true, and the theory is true, deductive reasoning must necessarily reach true conclusions. In case the assumptions are true and the conclusion false, the theory must be false and must be rejected or revised, due to the principle of invalidity.

Answer: employee relations
Explanation:
What is meant by employee relations?
This describes the effort of an organisation to ensure that they establish a positive relationship with their employees.
