Energy Cycle
The type of organism at the start of all food chains
Producers
The 3 processes of the water cycle
Evaporation, condensation and precipitation
The kind of organism that breaks down dead organisms and returns some of the carbon to the soil and the air
Decomposers
How much free nitrogen is in the atmosphere
78%
Matter is always _______
Recycled
Overlapping food chains
Food web
The process of water changing from a liquid to a gas
Evaporation
Burning these disrupt the carbon cycle and add too much carbon to the atmosphere
Fossil fuels such as oil and coal
The organism that "fixes" nitrogen for plants to use
Bacteria
Non-living parts in an ecosystem such as oxygen and carbon
Abiotic factors
A consumer that eats only meat
Carnivore
The process when water leaves plants
Transpiration
How animals get carbon
They eat it in food
Once nitrogen is "fixed" plants use it to build these
Proteins
What powers the food chain and causes evaporation to occur
The sun
This happens to energy as we move up the energy levels on an energy pyramid
It decreases (it is lost as heat)
3 types of precipitation
Snow, sleet, hail, rain
The 2 processes that help recycle carbon and oxygen
Photosynthesis and respiration
The reason free nitrogen in the air can't be used by organisms
It doesn't bond with other elements
The products of photosynthesis
Oxygen and glucose (food)
A consumer that eats a consumer that ate a producer
2nd level consumer
2 reasons why the water cycle is important
Recycles water, cleans water and moves water around
The chemical formula for glucose
C6H12O6
The force that can sometimes "fix" free nitrogen into forms organisms can use
Lightning
Diagram that shows how much energy is available at each feeding level
Energy pyramid
