Succession / Cycles
Succession and Adaptation / Cycles
| Term | Definition |
|---|---|
| Abiotic | Non-living factors in an ecosystem, including temperature, water, soil, and sunlight |
| Adaptation | A heritable trait that increases an organism's chances of survival and reproduction in a particular environment |
| Bacteria | Single-celled, prokaryotic microorganisms found in a wide range of environments, including soil, water, and the human body |
| Biotic | Living factors in an ecosystem, including plants, animals, fungi, and microorganisms |
| Carbon Cycle | The biogeochemical cycle by which carbon is exchanged between the atmosphere, biosphere, geosphere, and hydrosphere |
| Combustion | The process of burning organic matter, such as fossil fuels, that releases carbon dioxide and other gases into the atmosphere |
| Condensation | The process by which water vapor in the atmosphere cools and becomes liquid, forming clouds and eventually precipitation |
| Decomposition | The breakdown of organic matter by microorganisms, which releases nutrients back into the soil and atmosphere |
| Denitrification | The process by which bacteria in the soil convert nitrates back into nitrogen gas, releasing it into the atmosphere |
| Ecological Succession | The process by which an ecosystem changes over time, often following a disturbance, as different species replace one another |
| Ecosystem Stability | The ability of an ecosystem to resist change and maintain its structure and function in the face of disturbance or stress |
| Ecosystem | A community of living organisms and their non-living environment, interacting as a system to produce a stable and self-sustaining community |
| Evaporation | The process by which liquid water is converted into water vapor and released into the atmosphere |
| Fungi | A diverse group of eukaryotic organisms that includes yeasts, molds, and mushrooms, and play important roles in decomposition and nutrient cycling |
| Groundwater | Water that is stored in underground reservoirs, such as aquifers, and is an important source of drinking water and irrigation |
| Homeostasis | The ability of an organism or ecosystem to maintain a stable internal environment, even in the face of external changes or stress |
| Microorganism | A microscopic organism, such as a bacterium, virus, or fungus, that can only be seen with a microscope |
| Natural Disaster | A catastrophic event caused by natural processes, such as earthquakes, hurricanes, floods, and wildfires |
| Nitrogen Cycle | The biogeochemical cycle by which nitrogen is converted into various chemical forms and exchanged between the atmosphere, soil, and organisms |
| Nitrogen Fixation | The process by which certain bacteria convert nitrogen gas into ammonia or other forms of nitrogen that can be used by plants and animals |
| Nitrification | The process by which bacteria in the soil convert ammonium into nitrates, which can be taken up by plants and used to build organic molecules |
| Photosynthesis | The process by which plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into organic molecules and oxygen gas |
| Pioneer Species | The first species to colonize a newly formed or disturbed ecosystem, often hardy species that can survive in harsh conditions |
| Population Diversity | The variety of different species and genetic diversity within a population or community |
| Population | A group of organisms of the same species that live in a particular geographic area and interact with one another |
| Precipitation | Water that falls from the atmosphere, such as rain, snow, sleet, or hail |
| Primary Succession | The process of ecological succession that occurs in a newly formed, barren habitat, with no soil or organic matter, and no living organisms present |
| Protist | A diverse group of eukaryotic microorganisms that includes algae, amoebas, and ciliates, and play important roles in aquatic ecosystems |
| Respiration | The process by which organisms convert organic molecules into energy, releasing carbon dioxide and water as byproducts |
| Runoff | Water that flows over the surface of the land, often into streams, rivers, and lakes, and can carry pollutants and nutrients with it |
| Secondary Succession | The process of ecological succession that occurs in a previously inhabited area, with soil and organic matter already present, and some living organisms |
| Species Diversity | The variety of different species within a particular ecosystem, habitat, or geographic region |
| Symbiosis | A close and often long-term interaction between two or more different species, in which both partners benefit, or one partner benefits at no cost to the other |
| Transpiration | The process by which plants release water vapor into the atmosphere through small pores in their leaves |
| Variation | Differences among individuals within a population or species, including differences in physical traits, behavior, and genetic makeup |
| Water Cycle | The continuous process by which water is circulated through the atmosphere, biosphere, geosphere, and hydrosphere, including evaporation, condensation, precipitation, and runoff |
