Divine Flashcards
food web
the network of interconnected food chains in an ecosystem
pyramid of numbers
the same organisms that are in a food chain but the size of each level shows the number of organisms involved
energy flow
the transfer of energy that begins with the sun and passes from one organism to the next in the food chain
food chain
begins with a source of energy which is usually the sun
chlorophyll
a green chemical that traps the energy of the sun
photosynthesis
during photosynthesis the trapped energy is used to convert carbon dioxide gas and water into foods such as sugar and starch
Limiting factor
Any living or non living thing factor that controls the number of individuals a population
cellular respiration
occurs inside all living cells
bioaccumulation
the accumulation of pollutants in organisms though the levels of a food chain
the carbon cycle
a model showing how carbon ecosystems
carbon dioxide
a gas that is involved in the process of photosynthesis and that is produced by the process of cellular respiration
ecological succession
the gradual change in the make up of biological community over time
evaporation
the process in which a liquid changes into a gas or vapor
condensation
the process in which a gas or vapor changes in state to become a liquid
carrying capacity
the max number of individuals that an environment can support over a long period of time
global warming
the steady increase in the temperature of earths atmosphere
ground water
the water contained in the earth crust
pollutant
a material that causes pollution
pollution
a collective term for the different types of harmful material that are released into the environment
precipitation
the process in which the tiny droplets inside clouds combine to form large drops which fall on the earth as rain, snow or hail
run off
water that runs along the surface of the ground into lakes and rivers
top consumer
the carnivore at the end of the food chain
transpiration
the process in which water that is taken in though a plants roots evaporates from the plants leaves, stem and flowers
water cycle
the continuous movement of water though the environment
Natural selection
The process by which random evolutionary change selected by nature in a consistent orderly and non random way
Evolution
any change in the heritable traits within a population across generations
