What is the dental formula for a herbivore?

• Herbivores have a dental formula that emphasizes canines and incisors for tearing meat.

What does a dental formula of I4/4 C1/0 P3/3 M3/3 indicate?

• This indicates an animal with 4 upper and 4 lower incisors, 1 upper canine, 3 upper and lower premolars, and 3 upper and lower molars.

• This indicates an animal with 4 upper and 4 lower incisors, 2 upper canines, 3 upper and lower premolars, and 2 upper and lower molars.

• This indicates an animal with 2 upper and 2 lower incisors, 1 upper canine, 3 upper and lower premolars, and 4 upper and lower molars.

• This indicates an animal with 6 upper and 6 lower incisors, 1 upper canine, 2 upper and lower premolars, and 2 upper and lower molars.

What is the dental formula for a carnivore?

• 2-1-2-3/2-1-2-3

• 2-1-2-2/2-1-2-2

• 2-1-2-4/2-1-2-4

What is the significance of molars in herbivores?

• Molars are used for tearing meat in carnivores.

• Molars are crucial for grinding and processing plant material in herbivores.

• Molars help in the production of saliva for digestion.

• Molars are primarily for aesthetic purposes in herbivores.

What is the role of canines in carnivores?

• Canines are used for chewing vegetables.

• Canines are used for grasping and tearing flesh in carnivorous animals.

• Canines are primarily for defense against predators.

• Canines help in digging for food.

What are the three main types of dentition based on diet?

• Herbivore, Carnivore, Omnivore

• Insectivore, Frugivore, Folivore

• Detritivore, Saprotroph, Autotroph

• Piscivore, Planktivore, Myrmecophage

What does the notation 'I', 'C', 'P', and 'M' stand for in dental formulas?

• I = Incisors, C = Canines, P = Premolars, M = Molars

• I = Incisors, C = Canines, P = Molars, M = Premolars

• I = Incisors, C = Molars, P = Canines, M = Premolars

• I = Canines, C = Incisors, P = Molars, M = Premolars
