abiotic factors
nonliving parts of an ecosystem (sunlight, soil, temperature)
aquatic ecosystem
includes freshwater areas, estuaries, marine areas
bacteria
helps in the natural recycling process, a decomposer
balance
equilibrium in an ecosystem
biome
complex ecological community, extends over a large geographic area , consists of many ecosystems
biotic factors
living components of an ecosystem (the organisms)
carnivores
consumer that eats meat
co-exist
living in the same environment
community
interaction of all living things in an area
condensation
change of a vapor of gas into a liquid (i.e. condensation on a glass of lemonade in the summer)
conservation
sensible use of the earth's resources to avoid harming the environment
consumers
living things that eat food (i.e. animals) types of consumers: herbivore, carnivore, omnivore
control
part of an experiment that does not change, serves as the standard to compare other observations
deciduous
trees lose leaves in autumn/fall
decomposers
recycles matter and energy (examples from model ecosystem: aquarium snail, isopod), keeps the community clean by eating the dead organisms
decomposition
the breaking down of an organism back into nature
degrade
to make worse, harm
desert
little rain, extreme temperatures, drought resistant grass plants: sagebrush, cacti (adapted to conditions) animals: kangaroo rat, snakes, lizards, some birds, spiders, insects
ecology
study of the relationships between organisms and their environment
ecosystem
all living things in an area and their habitat (includes living and nonliving) abiotic factors + biotic factors = an ecosystem
environment
everything that surrounds an organism and influences it
estuary
where freshwater and salt water meet (coastal area)
eutrophication
increased nutrients in an ecosystem (i.e. too much fertilizer)
food chain
a picture that shows how each organism gets energy
food web
system of food chains
freshwater ecosystems
includes streams, rivers, lakes, marshes, swamps Salt levels are low, important nutrient to land plants and animals, supports a wide variety of plant and animal life
fungi
helps in the natural recycling process, a decomposer
germinate
the process of a seed beginning to sprout r beginning to grow into a plant
grasslands
also called savannas, rainfall is low or seasonal, dominant plant life is grass; other plants: buffalo grass, sunflower, goldenrods, clover large herbivores: bison, antelope, zebras, prairie dogs
habitat
physical place where an organism lives
herbivores
consumer that eats plants
interdependence
the relationship between plants and animals in an ecosystem
isopods
small animals with a segmented thorax, each part of the thorax has its own pair of legs
marine ecosystems
includes ocean areas and seas, high salt content, warmer, lots of sunlight near surface (examples: coral reefs, tide pools, beaches, ocean floor)
niche
position of an organism in a community of plants and animals
nutrients
substance required to nourish an organism
omnivores
consumers that eat both plants and animals
organisms
living things

measured on a scale of 0-14, where 7 is neutral (distilled water), 0-6 includes acid (orange juice), 7-14 includes basic (fertilizer, ammonia)
photosynthesis
chemical process where plants make their own food
pollutant
substance with damaging effects on the environment (i.e. acid rain, over-fertilization, road salt)
pollution
putting harmful things into the environment
population
a group of the same type of organism living in an area
precipitation
Liquid and solid forms of water from the atmosphere (examples: rain, snow, sleet, hail, drizzle, dew)
predator
an animal that eats another animal for food
prey
the animal that gets eaten
primary consumers
use plants for energy (anything that eats plants) examples: insects, fish, lizards, mice, birds, deer
producers
makes own food, gets energy from the Sun, example: plants
recycle
reusing materials
scavenger
feeds on dead organic matter that could have been killed by a predator
secondary consumers
get energy from primary consumers
