THE PROBLEMS FACED BY STUDENTS

A warm welcome and hearty good morning to this gathering. I, Badmus Samson Boluwatife, on behalf of the entire administration and student body, wholeheartedly welcome you Ma to Daystar High School. It is an honour to have a Personality like you as our Principal. We are delighted and privileged to have such a wonderful and highly experienced Woman of valour lead us to greater heights. We hope that with your leadership, energy, enthusiasm and passion for education and learning, our school will achieve greater excellence.

However, it is paramount to notify you ma, of some major shortcomings and inadequacies in the school which are detrimental to conducive and quality learning. These include but not limited to absence of a standard and well equipped library and computer laboratory, lack of competent teachers, unhygienic toilet facilities and poor waste disposal and management.

The current structure and availability of study materials in the school library is a major concern in promoting quality learning. This is also the situation of the school's computer laboratory. There. is need for restructuring and provision of relevant materials and equipment to improve the standard and quality of learning.

The school is also in dire need of adequate and competent teachers. Without these hardworking and competent teachers, the school is not complete. The school runs short of necessary subject teachers for government, financial accounting and chemistry. We earnestly ask that you see to the employment of standard, qualified and competent teachers.

Furthermore, there is a pressing and urgent need for conducive and hygienic learning environment.The situation of the school toilet facilities require immediate attention. I would like to suggest that new structure should be built and the existing ones should be repaired. Moreover, more waste baskets and waste disposal facilities should be provided all around the school premises so as to provide a clean learning environment and to avoid the students and staff room falling ill. This in turn promotes high level of productivity and progress.

I would like to add that students be allowed to engage in extra-curricular activities like sports, school clubs; jet clubs arts club, drama club and so on. These add to the experience and skills of the student other than the day-to-day classroom learning.

Conclusively, the aforementioned are the key problems within the school that require immediate and quality solutions, The entire student body look forward to great improvement with your intervention. |

We welcome you again to Daystar High School. We wish you a hitch-free journey in leading and piloting the affairs of the school. Congratulations!!

Welcome Ma!!!

Correct Answer: D) Niche

Explanation

The question is asking about a term used to describe all the different roles an organism plays in its habitat. This term is known as the organism's niche. A niche is the way an organism fits into its environment and includes things like what it eats, where it lives, and how it interacts with other organisms. It's important to understand that a habitat and a niche are not the same thing. A habitat is simply the physical environment where an organism lives, while a niche is the organism's specific role within that environment. For example, a habitat for a bird might be a forest, but its niche could be eating insects, building nests in trees, and competing with other birds for food and territory. Understanding an organism's niche is important for understanding how it interacts with other organisms in the same habitat. So, to sum up, the sum total of all the roles an organism plays in its habitat is known as its niche. The correct option for this question is option D.
