Nutrition in animals basics

What is the main function of the digestive system in animals?

• To produce hormones

• To break down food into nutrients for absorption

• To transport oxygen in the body

• To regulate body temperature

How do animals absorb nutrients from their food?

• Through the process of digestion and absorption in the small intestine.

• By inhaling nutrients through the air

• By absorbing nutrients through their skin

• Through photosynthesis in plants

Name the different types of teeth found in animals and their functions.

• Front teeth, back teeth, side teeth - Singing, whistling, humming

• Flat teeth, sharp teeth, pointed teeth - Smiling, laughing, talking

• Fangs, tusks, spurs - Chewing, biting, sucking

• Incisors, canines, premolars, molars - Cutting, tearing, grinding, crushing and grinding

Explain the classification of animals based on their diet - herbivores, carnivores, and omnivores.

• Herbivores eat plants, carnivores eat meat, and omnivores eat both plants and meat.

• Herbivores eat plants, carnivores eat both plants and meat, and omnivores eat meat.

• Herbivores eat both plants and meat, carnivores eat meat, and omnivores eat plants.

• Herbivores eat meat, carnivores eat plants, and omnivores eat both plants and meat.

Why is a balanced diet important for animals?

• A balanced diet leads to excessive weight gain in animals.

• A balanced diet provides essential nutrients for growth, development, and overall health.

• A balanced diet has no impact on the health of animals.

• Animals can survive on just one type of food without any negative consequences.

What is the role of enzymes in the digestion process of animals?

• Enzymes build up complex molecules for storage and later use.

• Enzymes break down complex molecules into simpler forms for absorption and utilization.

• Enzymes have no role in the digestion process of animals.

• Enzymes convert simple molecules into complex forms for excretion.

How does the length of the digestive system vary in herbivores, carnivores, and omnivores?

• The length of the digestive system is longer in herbivores, shorter in carnivores, and moderate in omnivores.

• The length of the digestive system is moderate in herbivores, longer in carnivores, and shorter in omnivores.

• The length of the digestive system is shorter in herbivores, longer in carnivores, and moderate in omnivores.

• The length of the digestive system is longer in carnivores, shorter in herbivores, and moderate in omnivores.

Discuss the importance of fiber in the diet of herbivores.

• Herbivores can thrive without fiber in their diet

• Fiber has no impact on herbivores' health

• Fiber is only needed for carnivorous animals

• Fiber is crucial for digestion, gut health, and dental health in herbivores.

What are some examples of animals that are herbivores, carnivores, and omnivores?

• Examples of herbivores: cows, rabbits, deer. Examples of carnivores: lions, tigers, wolves. Examples of omnivores: bears, humans, pigs.

• Examples of omnivores: lions, cheetahs, leopards

• Examples of carnivores: cows, horses, sheep

• Examples of herbivores: sharks, eagles, crocodiles

Explain the process of nutrient absorption in the small intestine of animals.

• Nutrient absorption in the small intestine of animals involves active transport and passive diffusion mechanisms to move nutrients across the intestinal membrane into the bloodstream.

• Nutrients are absorbed in the large intestine of animals

• Nutrient absorption in the small intestine is a passive process only

• Nutrients are absorbed through the skin of animals
