Nitrogen Cycle
This element makes up most of the air we breathe
What is nitrogen?
This is the first part of the digestive system
What is the mouth?
These organisms are the foundation of food chains and Webs, they produce their own food
(Hint: Don't say plants)
What are producers?
This macromolecule is primarily used for energy storage in the body
What are lipids?
This is the chemical formula for water
What is H2O?
This type of organism is responsible for breaking down dead tissue. Mushrooms and bacteria are examples.
What is a decomposer?
This organ is primarily responsible for nutrient absorption
What is the small intestine?
This is an example of a primary consumer
These are the building blocks of proteins
What are amino acids?
This is the total number of chromosomes that humans should have
What is 46?
This process is when nitrogen gas (N2) is converted in ammonia (NH3) by bacteria
What is nitrogen fixation?
This organ produces bile, which aids in breaking down fats
What is the liver?
This is a step in a food chain, representing the flow of energy
What is a trophic level?
This is an example of a nucleic acid
What is DNA?
This is the largest single organism that has ever existed
What is the blue whale?
This is what happens during nitrification (be specific)
What is ammonia/ammonium are converted into nitrites, which then get converted into nitrates
This is produced in the mouth to aid with chemical digestion
What is saliva?
All energy in a food chain/web originally comes from this source
What is the sun?
These molecules are a source of quick energy, while these molecules are a source of long term energy
What are carbohydrates = quick energy, and lipids= long term energy?
This type of cell lacks a membrane-bound nucleus
What is prokaryotic?
This is what plants do with the nitrogen they absorb from the soil?
What is they use them for proteins and DNA?
This process describes the contracting of muscles that pushes material through the digestive system
What is peristalsis?
This is the percentage of energy that is passed on between trophic levels of a food chain
What is 10%?
These macromolecules are essential to the structure of cell membranes
What are lipids?
This is the largest organ of the human body
What is the skin?
