STAAR Reporting Category #5
| 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) |
| Autotroph/producer | organism that makes their own food |
| Heterotroph/consumer | organism that eats other organisms to obtain energy |
