Remember Match each word with the correct definition. 1. \( \qquad \) B Biotie 2. \( \qquad \) Abiotic 3. \( \qquad \) Niche 4. \( \qquad \) Organism 5. \( \qquad \) Ecosystem 6. \( \qquad \) Interdependence Understand F living things depending on other living things Look at the word bank. Classify the words as biotic or abiotic using the T-chart.

Below is one way to match each word with its definition and then classify them as biotic (living) or abiotic (nonliving or environmental) factors. ───────────────────────────── Step 1. Match the Words with Their Definitions 1. Biotic  Definition: The living parts of an ecosystem—organisms that interact with one another.  Example: Plants, animals, bacteria 2. Abiotic  Definition: The nonliving parts of an ecosystem such as water, sunlight, air, and soil that influence living organisms. 3. Niche  Definition: The role or function an organism has within its ecosystem; this includes what it eats, where it lives, and how it interacts with other organisms. 4. Organism  Definition: Any individual living thing (plant, animal, fungus, bacterium, etc.). 5. Ecosystem  Definition: A community of living organisms (biotic factors) interacting with their physical environment (abiotic factors). 6. Interdependence  Definition: A state of mutual reliance where living things depend on one another for food, shelter, pollination, and other survival needs. ───────────────────────────── Step 2. Classify Each Term Using a T-Chart Remember that “biotic” refers to living elements and “abiotic” refers to nonliving components. Although an ecosystem includes both components, here the word itself represents an overall community.   Biotic Factors (Living Things and Their Roles):    • Biotic – pertains to all living components.    • Organism – any individual living thing.    • Niche – the role of an organism in its environment.    • Interdependence – describes how living things mutually rely on one another.   Abiotic Factors (Nonliving Environment Elements):    • Abiotic – refers to nonliving physical and chemical factors.    • Ecosystem – while it includes both living and nonliving components, the term is used to describe the overall system that includes abiotic (and biotic) factors. ───────────────────────────── Summary 1. Biotic: Living parts (organisms, their roles, and interrelationships) in an ecosystem. 2. Abiotic: Nonliving factors (like sunlight, water, temperature) in an ecosystem. 3. Niche: The specific role or job of an organism within its ecosystem. 4. Organism: Any living thing. 5. Ecosystem: A community where living things interact with one another and with nonliving elements. 6. Interdependence: The mutual reliance among living things for survival. This breakdown matches each definition to its term and shows which ones represent biotic factors and which represent abiotic factors.
