| Ecosystem | all the living things (plants, animals, etc.) in an area and the non-living things (like water, air, and soil) that they interact with |
| Organism | any living thing, like a plant, animal, or bacteria, that can function on its own and carry out life activities like growing and reproducing |
| Environment | everything around us, including the living and nonliving things, and the physical and chemical forces that affect them |
| Living | something that possesses the characteristics of life, including the ability to grow, reproduce, respond to stimuli, maintain homeostasis, metabolize, and is composed of cells |
| Nonliving | something is not alive and has never been alive |
| Producer | an organism that can create its own food, meaning it can generate energy from sunlight or chemicals without relying on other organisms |
| Consumer | an organism that cannot produce its own food and must obtain energy by eating other organisms, like plants or animals, making them dependent on producers within an ecosystem |
| Decomposer | an organism that breaks down dead or decaying organic matter, like plants and animals, releasing nutrients back into the environment by feeding on it |
| Nutrients | chemical substances found in food that are essential for an organism's growth, development, and proper functioning, providing the body with energy and building blocks to maintain life |
| Bacteria | microscopic living organisms that have only one cell. |
| Fungi | any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms |
| Detritivore | an organism that feeds on dead organic material |
| Food Web | a complex network of interconnected food chains within an ecosystem, illustrating how energy flows through a community by showing which organisms eat which other organisms |
| Transfer of Energy | the movement of energy from one object or system to another |
| Unbalanced Ecosystem | a state where the natural balance of an ecosystem is disrupted, leading to instability and potentially harmful consequences for the environment and its inhabitants. |
| Balanced Ecosystem | state of dynamic equilibrium within a community of organisms where the interactions between living things and their environment are sustainable and relatively stable |
| Photosynthesis | the biological process by which plants, algae, and certain bacteria use sunlight energy to convert carbon dioxide and water into glucose (sugar) and oxygen |
