What is photosynthesis and an example?
The process by which plants and other photoautotrophs generate carbohydrates and oxygen from carbon dioxide, water, and light energy.
An example of photosynthesis is how plants convert sugar and energy from water, air and sunlight into energy to grow.
100
The structure or organelle in which photosynthesis occurs.
Chloroplast.
100
What is cellular respiration and what are the 3 stages of cellular respiration (in order)?
The process by which glucose and oxygen break down to release stored energy.
1- Glycolysis 2- Kreb's Cycle 3- Electron Transport Chain
100
In this ecological pyramid which type of consumer gets only 10% of the energy stored in plants?
Secondary Consumers
100
A macronutrient that is composed of amino acids and that is essential to the growth of your body, like your muscles.
Protein
200
What are the reactants and products of Photosynthesis?
Photosynthesis Reactants: H2O and CO2.
Photosynthesis Products: Glucose and O2.
200
What is the effect of planting more trees in an area?
Increased trees means that there is more photosynthesis occurring. More photosynthesis means there is more food for animals, which means that more animals can live.
200
What are the reactants and products of Cellular Respiration?
Cellular Respiration Reactants: glucose and O2.
Cellular Respiration Products: H2O, ATP, and CO2.
200
If there are 100 Kcal of energy available in the producers, how much energy would be available in the herbivores?
1 kcal
200
A macronutrient that allows you to store energy, cushion organs, make certain hormones, absorb fat soluble vitamins, and helps with cell membrane integrity.
And how many types are there?
Fat
Trans fat, Saturated fat, and Unsaturated fat.

What are the 2 major stages/processes that occur in the chloroplast? Explain what they do.
1)Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH
2)The Calvin cycle, which takes place in the stroma, uses energy derived from ATP and NADPH to make GA3P(Glyceraldehyde 3-phosphate) from CO2
300
True or False?
In scientific terms, the word "photo" means light.
True.
300
_________ convert(s) glucose and oxygen into usable energy, carbon dioxide, and water?
The mitochondria.

The graph below shows the average daily grams consumed of soft drinks by age and gender in NYC.
How many more average daily grams of soft drinks does a 16-year-old male consume than a 16-year-old female?
314-247= 67 grams more of soft drinks consumed
300
This type of macronutrient gives your body a supply of quick energy.
Carbohydrates
400
What is a catalyst and why is it used during Photosynthesis?
The factor that's added to lower the activation energy is called a catalyst. Using catalysts leads to faster, more energy-efficient chemical reactions.
400
What are the products of the light dependent reactions? Define them.
1) NADPH (An energy-carrying molecule produced in the first stage of photosynthesis. It provides energy to fuel the Calvin cycle in the second stage of photosynthesis.)
2) O2 (Oxygen Molecule, byproduct of photosynthesis.)
3) ATP (Also provides energy that chloroplasts use to make sugar from carbon dioxide in the Calvin Cycle.)
400
What substances come out the Kreb's Cycle?
CO2 and energy in the form of ATP and NADH or NADP.

The graph below shows the percent consumers of specific food groups at breakfast by age group.
Which age group consumed more (bread, whole grain) and (fruit, whole) for breakfast? By how much? Explain.
Bread, whole grain (6% adults), (3% children)
Fruit, whole (20% adults), (12% children)
Adults consume 3% more bread, whole grain than children.
Adults consume 8% more fruit, whole than children.

Macronutrients provide the body with energy, which we measure using a unit called ________?
Define it once guessed!
Calories(kcal)
A unit of energy used to measure the energy in nutrition/food and 1 Calorie is equal to 1000 kilocalories.

Explain how the reaction of Cellular Respiration is related with Photosynthesis.
The inputs of photosynthesis are the outputs of respiration and the outputs of photosynthesis are the inputs of respiration. For this reason, the reactions are often said to be "opposite."
500
What is the formula for cellular respiration?
C6H12O6 + 6O2 → 6CO2 + 6H2O
500
What are all the terms that can be used to describe the Orca whale?
Tertiary consumer, carnivore, heterotroph and top predator.
500
What is the function of glucose in carbohydrates?
The body uses glucose directly as energy source in muscle, brain and other cells. Some of the carbohydrates cannot be broken down and they get either fermented by our gut bacteria or they transit through the gut without being changed.
