What is an organism that produces their own food?

What is a producer?

From where does the energy in most living organisms ultimately originate?

What is the sun?

What does combustion require?

What is oxygen as well as something to burn such as wood or monosaccharides.

When proteins are eaten, they are broken down into their amino acids.  If your cells are short on amino acids, what happens to the amino acids that come from the proteins you eat? What happens if your cells have plenty of amino acids?

If your cells do not have enough amino acids, the amino acids from the proteins you eat are sent to your cells so that your cells can make the proteins they need.  If your cells have plenty of amino acids the amino acids from the proteins you eat are either burned for energy or converted into carbohydrates or fats.

Why is the mitochondrion called the "powerhouse" of the cell?

The mitochondrion is where the the majority of energy in the combustion process is released in step 3, which takes place here.

What is a consumer that eats producers exclusively?

What is an herbivore?

200

What is the name of the chemical process that converts energy into food?

What is combustion?

200

What are three macronutrients?

Carbohydrates, fats, and proteins.

200

In what order does the body prefer to burn the macronutrients?

The body prefers to burn carbohydrates, then fats, and then proteins (or amino acids).

200

Why is it important to eat either animal protein or a wide variety of plant protein?

Your cells must make proteins by linking together amino acids.  There are several amino acids your body cannot make.  Thus you must get them from food. Without those amino acids, your cells will not be able to make the proteins they need to make.  Animal proteins have these amino acids in plentiful supply. Plant proteins rarely have all of them.  Thus, people who eat only plants must get a wide variety of plant protein to make sure they get those amino acids.

What is a consumer that eats only other consumers?

What is a carnivore?

300

What do calories measure?

Calories measure energy.  The can measure how much energy is in food, or how much energy organisms have expended.
300

What does combustion produce?

Combustion produces energy, carbon dioxide, and water.

300

Which is larger a monosaccharide, a disaccharide, or polysaccharide?

Polysaccharides are the largest.

300

When normalized by weight, which has a higher BMR: a horse or a mouse?

In general, the smaller the mammal the higher the normalized BMR, because the more the energy the animal has to spend keeping its internal temperature high.  Thus the mouse has the higher normalized BMR.

What is a consumer that eats both producers and other consumers?

What is an omnivore?

400

Where does combustion take place?

It takes place in the cell.

400

Label the following as a consumer, producer, or decomposer. 

Mushroom

Evergreen Bush

Worm

Algae

Mushroom-Kingdom Fungi-Decomposer

Evergreen-Producer

Worm-Consumer

Algae-Producer they are an important source of photosynthesis on the planet.

400

What are two basic kinds of fats? How can you distinguish them?

Fats are either saturated fats or unsaturated fats.  You can distinguish them while they are at room temperature.  Saturated fats are usually solid at room temperature, while unsaturated fats are usually liquid.

400

Which type of animal has a higher BMR: an endothermic animal or an ectothermic animal?

Endothermic animals have a higher BMR.  The BMR tracks the minimum amount of energy needed to survive.  Both endothermic and ectothermic animals have involuntary muscles, etc., that need energy, but only endothermic animals expend energy to keep their internal temperatures high.

500

What is an organism that eats living producers and/or consumers for food?

What is a consumer?

500

How many basic steps are involved in the combustion of food? Why do cells do it in such a complex way?

The combustion of food takes place in three basic steps.  This allows for the gentle release of energy so that the cell doesn't burn up from the combustion process.

500

What is the main thing that macronutrients provide?

They provide energy.

500

What is protein made of?

What is long strings of amino acids?

500

What type of animal cannot be active on a very cold day: endothermic or ectothermic animal.

Ectothermic animals cannot be active on a very cold day.  Since their body temperatures are not held constant, the colder days reduce the speed at which the chemical reactions can occur in their bodies.  This makes them sluggish.
