Nutrient Cycles
Water Cycle
100
It's where all of life on Earth exists.
What is the biosphere?
100
These use energy they take in from the environment to convert inorganic molecules into complex organic molecules.
What are autotrophs?
100
This is a series of steps in which a large fish eats a small fish that has eaten algae.
What is food chain?
100
Nutrients move through an ecosystem by this process.
What is a biochemical cycle?
100
This is the name of the process by which water changes from a liquid to a gas.
What is evaporation?
200
These are groups of different species that live together in a defined area?
What is community?
200
Sunlight
What is the main energy source for life on the Earth?
200
One eats only plants and the other eats only other animals.
What is herbivores and carnivores?
200
These organisms are responsible for changing nitrogen gas into ammonia.
What are bacteria that live on the roots of plants.
200
This process allows plants to lose moisture from the surface of the leaves.
What is transpiration?
300
This process enables plants to use light energy to make chemical energy.
What is photosynthesis?
300
It is a series of steps in which organisms transfer energy by eating and being eaten.
What is a food chain?
300
This nutrient cycle does not involve a stage where the chemical enters the atmosphere.
What is the phosphorus cycle?
300
This process in the water cycle allows for the formation of clouds.
What is condensation?
400
This shows the feeding relationships among various organisms in an ecosystem.
What is a food web?
400
These organisms make up the first tropic level of any food web.
What are producers?
400
This is the total amount of living tissue within a given tropic level.
What is biomass?
400
Both these nutrient cycles have the atmosphere as the major reservoir for the nutrient.
What are the carbon cycle and the nitrogen cycle.
400
Rain, snow, sleet or hail.
What is precipitation?
500
10%
What is the available energy transferred from on tropic level to the next?
500
This process allows autotrophs other than plants to produce energy-rick carbohydrates from the energy stored in chemical bonds.
What is chemosynthesis?
500
These are organisms that are at the top of a food web.
What are top-level carnivores?
500
It is the area of the Earth that is considered to be more nutrient rich.
What is the land?
500
The two parts of the water cycle that plants are responsible for.
What is transpiration and root uptake.
