4.1 Roles of Living Things
Name an example of a producer
What are plants (trees, bushes, flowers, algae)
A straight line of energy in an ecosystem
What is a food chain
Plants receive less than this percentage of the Sun's energy
What is 1%
These 4 elements make up Earth and our body
What are oxygen, carbon, hydrogen, and nitrogen
Method by which lake or ocean water enters the atmosphere
Name an example of a decomposer
What is bacteria and fungi
A complex network of interconnecting feeding relationships in an exosystem
What is a food web
Rough amount (%) that travels from one trophic level to the next
Water lost from plants leaves into the atmosphere is called this
A type of plant that plays a special role in the nitrogen cycle
What is a legume (beans, peanuts)
Something that makes their own food.
What is an autotroph?
I am NOT displayed in a food web, but am everywhere
What are decomposers
The level has the most amount of biomass in it's ecostyem
What are producers
Plants and animals are "the perfect match" because of these two opposite processes
Photosynthesis and Respiration
The amount of organic matter present in a trophic level
What is biomass
The largest trophic level
What are the producers
I am magnified as I travel up the trophic levels
What is bio-magnification or bio-accumilation
The three types of ecological pyramids
What are energy, biomass, and number
The building blocks of protein are called these
What are amino acids
Bacteria, Fungi, and Earthworms are examples
What are decomposers
These animals are known as scavengers
What are coyotes, hyenas, vultures
An example of a more stable ecosystem
What is the deciduous forest or rain forest
Energy from each trophic level is not passed on because of this
What is metabolism (breathing, repairing cells, moving, etc.)
What are organic compounds (nitrate and nitrite)
The increasing concentration of DDT at higher levels throughout the food chain is called this
What is bio-magnification or bio-accumulation
