Question
Answer
Ecological Succession   how an area changes over time from an area that is uninhabitable to one that is able to support a healthy ecosystem  
Organism   a living thing; exhibits all 5 characteristics of life (ORGAN)  
Population   a group of organisms of the same species that live in the same area and interbreed  
Community   a group of different populations (different species) that live in the same area  
Biotic Factor   a living thing in an ecosystem; ex. plant, animal, bacteria  
Abiotic Factor   a nonliving thing in an ecosystem; ex: water, rocks, earth  
Habitat Requirement   something necessary to make a good place to live: shelter and space, and access to food and water  
Limiting Factors   any factor that limits the size of a population by restricting its numbers, reproduction, or distribution  
Carrying Capacity   the maximum population a habitat can sustain  
Predation   a relationship between two species where one species hunts (predator) and eats the other species (prey)  
Competition   a relationship between two species where they both require the same resource (food, water, shelter, space) and must compete for it  
Parasitism   a relationship between two species where one species is helped and the other species is harmed  
Commensalism   a relationship between two species where one species is helped and the other species is not affected  
Mutualism   a relationship between two species where both species are helped  
Autotroph   an organism that can use photosynthesis to make its own food: "self-feeding"  
Heterotroph   an organism that cannot use photosynthesis to make its own food and must eat other organisms to survive: "other-feeding"  
Trophic Level   the position a species occupies in a food chain; ex. producer, primary consumer, secondary consumer  
Food Chain   a sequence of organisms that shows how energy is transferred from plants, to plant eaters, to meat eaters and so on  
Food Web   a combination of several food chains within an ecosystem  
Ecological Pyramid   a graphic representation of the amount of biomass present in each trophic level of a food chain; producers are always on the bottom, then primary consumers, then secondary consumers and so on  
Microorganisms   living things that can only be seen with a microscope; ex. bacteria, protists  
Biomes   areas with similar climate and conditions: ex. rainforests, grasslands, desert, wetland  
Resource Base   amount of total available food, water , shelter and space; toal amount of biotic and abiotic factors available for organims  
Carbon Cycle   the cyclic movement of carbon atoms between living things (organic carbon) and their environment (inorganic carbon)  
Nitrogen Cycle   the cyclic movement of nitrogen atoms between living things (organic nitrogen) and their environment (inorganic nitrogen)
