Study Notes
Nutrition in Animals
Types of Nutrition
- Autotrophic nutrition: Animals that can produce their own food, such as through photosynthesis (e.g., corals).
- Heterotrophic nutrition: Animals that cannot produce their own food and need to consume other organisms or organic matter (e.g., humans, animals).
Nutrient Requirements
- Macronutrients:
- Carbohydrates
- Proteins
- Fats
- Micronutrients:
- Vitamins
- Minerals
- Water: essential for various bodily functions
Modes of Nutrition
- Herbivory: feeding on plants (e.g., cows, deer)
- Carnivory: feeding on animals (e.g., lions, sharks)
- Omnivory: feeding on both plants and animals (e.g., humans, bears)
- Detritivory: feeding on dead organic matter (e.g., earthworms)
Nutrient Uptake
- Ingestion: taking in food through the mouth
- Digestion: breaking down food into smaller molecules
- Absorption: taking in nutrients into the bloodstream
- Assimilation: using absorbed nutrients for energy, growth, and maintenance
Nutrient Utilization
- Energy production: using nutrients for energy production (e.g., ATP)
- Growth and development: using nutrients for growth and development
- Maintenance: using nutrients for maintaining bodily functions
