Matter
This type of matter is made of any one kind of atom, such as oxygen or gold?
What is element
All living organisms are made of these basic units of life?
What are cells.
Respiration by all organisms (producers and consumers) exhaust CO2 back into their environment?
What is release
This cycle shows how water moves through the environment?
This shows many connected food chains in an ecosystem?
What is a food web
This type of substance is formed when two or more elements are chemically combined, like water (H2O)?
What is compound
This process allows plants to move their own food using sunlight, water, and carbon dioxide?
What is photosynthesis
Carbon moves through food webs as organisms eat others?
What is transfer
This cycle explains how carbon moves through living and non-living things?
What are carbon cycles
What is energy loss
This type of mixture is evenly mixed throughout and looks the same everywhere like salt water?
What is homogeneous mixture
This type of organism can make it's own food and is also called a Producer?
What is autothroph
Water is essential for Photosynthesis and respiration, moving through organisms and the environment?
What is water cycle
These two substances cycle through the ecosystems with low energy?
What are water and carbon
This connects energy flow with the cycling of matter?
What is a food web
Air is an example of this type of matter made of different gases that are not chemically bonded?
This body system in a human is responsible for transporting oxygen and nutrients throughout the body?
What is the circulatory system
Producer convert light energy, water (H2O) and carbon dioxide (CO2) into glucose (chemical energy)?
What is photosynthesis
Matter is recycled in ecosystems, but this is not?
What is energy
These organisms break down dead matter and return nutrients to the environment?
What are decomposers
This method can be used to separate a mixture based on differences in boiling points?
What is distillation
This process allows organisms to pass traits from parents and to their offspring using DNA?
What is heredity
Only ~10% of energy transfers to the next level; the rest is used for life processes (respiration or lost as heat, limiting food change length?
What is energy loss
This cycle includes ammonification, nitrification, and denitrification processes to convert atmospheric nitrogen into forms for living things.
what is nitrogen cycle
Predators in a food web that have no natural predators of their own
apex predators
