Ch 11 G.H. Biology

Guest Hollow Biology Chapter 11 vocab

abiotic factor nonliving aspect of the environment such as sunlight and soil
biomass total mass of organisms at a trophic level
biotic factor living aspects of the environment, including organisms of the same and different species
carnivore consumer that eats animals
chemoautotroph producer that uses energy from chemical compounds to make food by chemosynthesis
competitive exclusion principle principle of ecology stating that two different species cannot occupy the same niche in the same place for very long
decomposer organism that breaks down the remains of dead organisms and other organic wastes
detritivore decomposer that consumes detritus
detritus substance composed of dead leaves, other plant remains, and animal feces that collects on the soil or at the bottom of a body of water
ecology branch of biology that is the study of how living things interact with each other and with their environment
food chain diagram that represents a single pathway through which energy and matter flow through an ecosystem
food web diagram that represents multiple intersecting pathways through which energy and matter flow through an ecosystem
habitat physical environment in which a species lives and to which it has become adapted
herbivore consumer that eats producers such as plants or algae
niche role of a species in its ecosystem that includes all the ways the species interacts with the biotic and abiotic factors of the ecosystem
omnivor consumer that eats both plants and animals
photoautotroph producer that uses energy from sunlight to make food by photosynthesis
saprotroph decomposer such as a fungus or protozoan that feeds on any remaining organic matter that is left after other decomposers do their work
scavenger decomposer that consumers the soft tissues of dead animals
trophic level feeding position in a food chain or food web, such as producer, primary consumer, or secondary consumer
aquifer underground layer of rock that stores water
biogeochemical cycle interconnected pathways through which water or a chemical element such as carbon is continuously recycled through the biotic and abiotic components of the biosphere
condensation process in which water vapor changes to tiny droplets of liquid water
evaporation process in which liquid water changes to water vapor
exchange pool part of a biogeochemical cycle that holds an element or water for a short period of time
groundwater water that exists in the ground either in the soil or in rock layers below the surface
nitrogen cycle interconnected pathways through which nitrogen is recycled through the biotic and abiotic components of the biosphere
nitrogen fixation process of changing nitrogen gas to nitrates that is carried out by nitrogen-fixing bacteria in the soil or in the roots of legumes
precipitation water that falls from clouds in the atmosphere to Earth’s in the form of rain, snow, sleet, hail, or freezing rain
reservoir part of a biogeochemical cycle that holds an element or water for a long period of time
runoff precipitation that falls on land and flows over the surface of the ground
sublimation process in which ice and snow change directly to water vapor
transpiration process in which plants give off water vapor from photosynthesis through tiny pores, called stomata, in their leaves
water cycle interconnected pathways through which water is recycled through the biotic and abiotic components of the biosphere
aphotic zone area in aquatic biomes deeper than 200 meters
aquatic biome water-based biomes, defined by the availability of sunlight and the concentration of dissolved oxygen and nutrients in the water
climate average weather in an area over a long period of time
dormancy state in which a plant slows down cellular activity and may shed its leaves
estuary a partly enclosed coastal body of water with one or more rivers or streams flowing into it, and with a free connection to the ocean
freshwater biome aquatic biome such as a pond, lake, stream, or river in which the water contains little or no salt
growing season period of time each year when it is warm enough and wet enough for plants to grow
intertidal zone in marine biomes, the narrow strip along the coastline that is covered by water at high tide and exposed to air at low tide
marine biome aquatic biome in the salt water of the ocean
photic zone area in an aquatic biome that extends to a maximum depth of 200 meters
phytoplankton bacteria and algae that use sunlight to make food
terrestrial biome a biome of or pertaining to land, as in terrestrial ecosystem
wetland area that is saturated with water or covered by water for at least one season of the year
zooplankton tiny animals that feed on phytoplankton
