Animal Ecology (Fauna) Part 1: Food Acquisition and Body Temperature

The video tutorial explores the essential nutrients required for survival, focusing on macronutrients and micronutrients. It discusses animal dietary classifications and the evolution of digestive systems. The tutorial also covers thermoregulation, highlighting how animals maintain body temperature through various adaptations. Finally, it introduces the role of water in essential bodily functions.

Which of the following is considered a macronutrient essential for cellular function?

• Zinc

• Copper

• Carbon

• Iron

What is the primary role of proteins in animal bodies?

• To provide energy

• To grow and repair tissues

• To store genetic information

• To act as a solvent

Which mineral is crucial for bone growth and repair in animals?

• Zinc

• Sodium

• Iron

• Calcium

How are animals classified based on their diet?

• Predators, Prey, Scavengers

• Producers, Consumers, Decomposers

• Herbivores, Carnivores, Omnivores

• Mammals, Birds, Reptiles

What type of digestive system do earthworms possess?

• Incomplete digestive tract

• Gastrovascular cavity

• Alimentary canal

• Ruminant stomach

Which of the following is a characteristic of endotherms?

• They cannot regulate their body temperature

• They have a constant internal temperature

• They rely on external heat sources

• They are cold-blooded

What is a common behavioral adaptation for thermoregulation in animals?

• Growing thicker fur

• Seeking shade or sun

• Developing blubber

• Changing fur color

How do marine mammals like whales minimize heat loss?

• By reducing blood flow to the skin

• By having large ears

• By using blubber

• By basking in the sun

What is the function of brown adipose tissue in some mammals?

• To produce heat

• To store carbohydrates

• To aid in digestion

• To store water

What is the evolutionary significance of goosebumps in humans?

• They help in cooling the body

• They are a response to fear

• They aid in digestion

• They are a relic from ancestors with more body hair
