Homeostasis Story
Homeostasis Storyline
| Term | Definition |
|---|---|
| Abiotic | Nonliving parts of the environment, such as water, sunlight, temperature, and soil. |
| Adaptation | A trait or behavior that helps an organism survive in its environment. |
| Biodiversity | The variety of different living things in an area. |
| Biotic | Living parts of the environment, such as plants, animals, and bacteria. |
| Cell Wall | A rigid outer layer that supports and protects plant cells. |
| Cellular Respiration | The process by which cells break down food to release energy. |
| Chloroplast | A structure in plant cells where photosynthesis takes place. |
| Food Chain | A simple path showing how energy moves from one organism to another. |
| Food Web | A group of connected food chains showing how organisms share energy in an ecosystem. |
| Homeostasis | The ability of an organism to maintain a stable internal environment. |
| Mitochondria | Structures in cells that produce energy; often called the “powerhouse” of the cell. |
| Photosynthesis | The process by which plants use sunlight to make food from carbon dioxide and water. |
| Products | Substances that are made during a chemical reaction. |
| Reactants | Substances that are used at the start of a chemical reaction. |
| Trophic Level | A position an organism holds in a food chain or food web. |
| Acidification | The process by which something becomes more acidic (lower pH). |
| Calcifier / Calcification | An organism that builds shells or skeletons using calcium carbonate. |
| Calcium Carbonate | A chemical compound used by organisms like corals and shellfish to make shells and skeletons. |
| Carbon Cycle | The movement of carbon through living things, the atmosphere, water, and Earth. |
| Carrying Capacity | The largest population an environment can support without running out of resources. |
| Cell Membrane | A thin, flexible layer that surrounds a cell and controls what enters and leaves it. |
| Community | All the different populations of living organisms in the same area. |
| Diffusion | The movement of particles from an area of high concentration to low concentration. |
| Ecosystem | All the living and nonliving things in an area and how they interact. |
| Energy Pyramid | A diagram that shows how energy decreases as it moves up trophic levels in a food chain. |
| Genetic Drift | A random change in traits in a population over time, especially in small populations. |
| Keystone Species | A species that has a large impact on its ecosystem, even if its population is small. |
| Limiting Factor | Anything that restricts the size of a population, such as food, water, or space. |
| Natural Selection | The process by which organisms with helpful traits are more likely to survive and reproduce. |
| Ocean Acidification | The decrease in ocean pH caused by increased carbon dioxide in the water. |
| Osmosis | The movement of water across a cell membrane from high to low concentration. |
| pH | A scale that measures how acidic or basic a substance is. |
| Population | A group of the same species living in the same area. |
| Selective Pressure | An environmental factor that affects an organism’s ability to survive and reproduce. |
| Active Transport | The movement of substances across a cell membrane using energy. |
| Ectotherm | An organism that relies on the environment to control its body temperature (such as reptiles). |
| Endotherm | An organism that controls its body temperature using internal energy (such as mammals and birds). |
| Feedback Mechanism | A process in which the result of a system affects how the system continues to work. |
| Fermentation | A process that releases energy from food without using oxygen. |
| Myoglobin | A protein in muscle cells that stores oxygen for energy use. |
| Negative Feedback Loop | A feedback mechanism that reverses a change to maintain balance in the body. |
| Nitrogen Cycle | The movement of nitrogen through the atmosphere, soil, living organisms, and water. |
| Passive Transport | The movement of substances across a cell membrane without using energy. |
| Permeability | How easily substances can pass through a membrane. |
| Positive Feedback Loop | A feedback mechanism that increases or amplifies a change. |
| Thermoregulation | The ability of an organism to maintain a stable body temperature. |
| Trophic Cascade | A chain reaction in an ecosystem that occurs when changes at one trophic level affect other levels. |
| Variation | Differences in traits among individuals in a population. |
| Vasoconstriction | The narrowing of blood vessels to reduce heat loss. |
