**Matching:**<br /><br />* **Weather:** The short-term state of the atmosphere at a particular time and place.<br />* **Climate:** The long-term average weather conditions in a particular region.<br />* **Population Density:** The number of individuals of a species per unit area or volume.<br />* **Density-dependent limiting factors:** Factors that limit population growth more strongly as population density increases (e.g., competition, disease).<br />* **Density-independent limiting factors:** Factors that limit population growth regardless of population density (e.g., natural disasters, weather events).<br />* **Low-pressure system:** A weather system associated with rising air, often bringing clouds, precipitation, and unsettled weather.<br />* **High-pressure system:** A weather system associated with sinking air, often bringing clear skies and calm weather.<br />* **Ecology:** The study of the interactions between organisms and their environment.<br />* **Ecosystem:** A community of organisms and their physical environment interacting as a system.<br />* **Abiotic:** Non-living components of an ecosystem (e.g., temperature, sunlight, water).<br />* **Biodiversity:** The variety of life in a particular habitat, ecosystem, or the world.<br />* **Biotic:** Living components of an ecosystem (e.g., plants, animals, fungi).<br />* **Biome:** A large geographic area characterized by specific climate conditions and dominant plant and animal life.<br />* **Community:** All the populations of different species living and interacting in a particular area.<br />* **Niche:** The role an organism plays in its environment, including its interactions with other organisms and its use of resources.<br />* **Natality:** The birth rate of a population.<br />* **Mortality:** The death rate of a population.<br />* **Immigration:** The movement of individuals into a population.<br />* **Emigration:** The movement of individuals out of a population.<br />* **Extinct:** A species that no longer exists anywhere on Earth.<br />* **Endangered:** A species at high risk of extinction in the near future.<br />* **Extirpated:** A species that no longer exists in a particular area but still exists elsewhere.<br />* **Threatened:** A species likely to become endangered in the near future.<br />* **Bioaccumulation:** The gradual accumulation of substances, such as pesticides or other chemicals, in an organism.<br />* **Biomagnification:** The increasing concentration of a substance, such as a toxic chemical, in the tissues of organisms at successively higher levels in a food chain.<br />* **Population:** A group of individuals of the same species living in the same area at the same time.<br />* **Limiting Factor:** Any factor that restricts the size of a population.<br />* **Carrying Capacity:** The maximum population size that an environment can sustainably support.<br />* **Autotrophs:** Organisms that can produce their own food using energy from sunlight or inorganic chemicals (e.g., plants). Also known as producers.<br />* **Heterotrophs:** Organisms that obtain energy by consuming other organisms (e.g., animals, fungi). Also known as consumers.<br />* **Producers:** Organisms that produce their own food through photosynthesis or chemosynthesis.<br />* **Primary consumers:** Herbivores that eat producers.<br />* **$2^{nd}$ level consumer, $3^{rd}$ level consumer:** Carnivores or omnivores that eat other consumers.<br />* **Carnivore:** An animal that primarily eats other animals.<br />* **Omnivore:** An animal that eats both plants and animals.<br />* **Herbivore:** An animal that primarily eats plants.<br />* **Decomposer:** Organisms that break down dead organic matter and recycle nutrients back into the ecosystem (e.g., bacteria, fungi).<br />* **Evaporation:** The process of liquid water changing into water vapor.<br />* **Condensation:** The process of water vapor changing into liquid water.<br />* **Precipitation:** Any form of water that falls from the atmosphere to the Earth's surface (e.g., rain, snow, hail).<br /><br /><br />This provides definitions for all the terms listed.
