1. What is the term used to describe a group of organisms that are located in one place and belong to the same species?

1. The term used to describe a group of organisms that are located in one place and belong to the same species is C) population. A population consists of all the individuals of a particular species living in a specific area. It is a fundamental unit in ecology and is characterized by the interactions among its members and with their environment. This term emphasizes the focus on a specific species within a defined geographical area.

2. The four elements that make up approximately 96% of living matter are D) carbon, hydrogen, nitrogen, and oxygen. These elements are commonly found in biological molecules and play vital roles in the structure and functioning of living organisms. Carbon serves as the backbone of organic compounds, hydrogen is involved in many biological reactions and acts as a source of energy, nitrogen is required for the synthesis of proteins and nucleic acids, and oxygen is involved in respiration and provides the necessary energy for cellular processes.

3. The correct answer would be A) Kingdom. The hierarchical classification system in biology includes different levels, such as domain, kingdom, phylum, class, order, family, genus, and species. Each level represents a progressively narrower group of organisms. So, "kingdom" includes all the other options (domain, phylum, etc.) as it is a broader category encompassing a larger diversity of organisms.
