Explanation:

• Biotic Factors: These are living or once - living things in an ecosystem. So, it matches with O.
• Abiotic Factors: Non - living parts of an ecosystem. So, it matches with K.
• Ecosystem: All the living and non - living things that interact in one environment. So, it matches with M.
• Habitat: The natural place where an organism lives and finds food, water, and shelter. So, it matches with S.
• Population: A group of the same species living in the same area. So, it matches with Q.
• Community: All the different populations that live together in one area. So, it matches with F.
• Environment: The surroundings or conditions in which living things exist. So, it matches with P.
• Organism: Any living thing (animal, plant, fungus, bacterium). So, it matches with N.
• Sunlight: The main source of energy for most ecosystems. So, it matches with J.
• Water: Affects where organisms can survive. So, it matches with R.
• Temperature: Affects where organisms can survive. So, it matches with R.
• Soil: Provides nutrients and support for plants. So, it matches with C.
• Air (Oxygen & Carbon Dioxide): Gases that organisms use for respiration and photosynthesis. So, it matches with E.
• Rocks & Minerals: Form part of the geosphere and influence soil composition. So, it matches with T.
• Climate: The average weather conditions in an area over time. So, it matches with B.
• Producers: Organisms that make their own food (plants, algae). So, it matches with G.
• Consumers: Organisms that eat other organisms for energy. So, it matches with A.
• Decomposers: Organisms that break down dead matter (fungi, bacteria). So, it matches with U.
• Predator: An animal that hunts and eats other animals. So, it matches with D.
• Prey: An animal that is hunted and eaten by another. So, it matches with L.
• Symbiosis: A close relationship between two different organisms living closely together. So, it matches with I.
• Competition: When organisms fight for the same resources like food or space. So, it matches with H.
