What do herbivores eat?
Plants!
What are sharp, pointy teeth that are used for grabbing and tearing called?
Canines
Which of the macromolecules is broken down and then built up again to form various structures and perform various functions in the body?
Proteins!
True or false: living organisms USE all of the potential energy they consume.
False. Living organisms will always produce some waste product (energy does unused).
What is a niche?
An organism's role in its environment.
What part of the digestive tract is more pronounced in herbivores and is responsible for digesting plant matter?
Cecum
What are sharp, flat teeth known as incisors used for?
True or False: Carbohydrates are the BEST source of long-lasting energy.
False, lipids are the best source of energy.
In a food chain or food web, what do the arrows show?
Arrows show the flow of energy from the organism being eaten to the organism doing the consuming!
Each step in a food chain or web is called?
Trophic Level
Structure and function
What are flat teeth used for grinding called?
Molars
What atom in macromolecules is directly related to increased energy?
Carbon. Because Carbon can create more bonds, more energy can be released.
Which trophic level contains the MOST energy in a food web or energy pyramid?
Producers
A triangle-shaped diagram or a graphical representation of how energy is produced and how it flows from one group to another or one organism to another is called?
Energy Pyramid
True or false? Omnivores have very short digestive tracts.
False. Omnivores have the most complex diets of all living organisms. Their digestive tracts are longer in order to extract all the nutrients they need!
A skull that has varied teeth including incisors, canines, and molars would likely belong to which feeding niche?
Omnivores!
When bonds break down in macromolecules, what happens to the energy?
Energy is released (and the body can use it!)
Example must be a living organism that eats primary consumers (herbivores!)
A model that illustrates multiple sets of energy-transfer relationships is called?
What cross-cutting concept do the following statements reflect?
Carnivores have little to no cecum at all. Herbivores have longer cecums for digesting plants. Omnivores have longer small intestines for digesting their varied diet.
Patterns
Why did humans experience a dramatic increase in brain size around 1.8 million years ago?
Humans began to eat more meat!
False. Carnivores would have high proteins and fats, with and little to no carbohydrates in their diet.
Why is an energy pyramid shaped like a triangle?
An energy pyramid is shaped like a triangle because it shows the LOSS of energy as you move upward in the trophic levels.
A physical characteristic or behavior that helps an organism survive is called?
Adaptation!
