Define the term "ecosystem."

Define the term "ecosystem."

• A. A group of the same species in a given area
• B. Interactions between living organisms and their physical environment
• C. A hierarchical classification of organisms
• D. The process of photosynthesis

Answer: (B)

The term "ecosystem" refers to the complex network of interactions between living organisms (such as plants, animals, fungi, and microorganisms) and their physical environment (which includes the non-living components like soil, water, and air). This definition highlights the dynamic relationships and exchanges of energy and nutrients that occur within a specific area, illustrating how species interact with each other and their surroundings to form a functioning unit. In ecological terms, ecosystems can range in size from small ponds to vast tropical forests, and they encompass both biotic factors (living components) and abiotic factors (non-living components). The interactions within an ecosystem can include food webs, nutrient cycles, and habitats, all crucial for maintaining balance and biodiversity. The other options describe different biological concepts: a group of the same species refers to a population, a hierarchical classification pertains to taxonomy, and photosynthesis is a specific biological process. These distinctions clarify why the correct definition centers on the interactions within an ecosystem.
