Study Notes
Nutrition in Animals
Types of Nutrition
- Autotrophic Nutrition: Producing own food through photosynthesis (e.g., plants, algae)
- Heterotrophic Nutrition: Obtaining energy by consuming other organisms (e.g., animals, fungi)
Nutritional Requirements
-
Macronutrients:
- Carbohydrates (energy source)
- Proteins (building blocks for growth and repair)
- Fats (energy source and hormone production)
-
Micronutrients:
- Vitamins (regulate metabolism and maintain health)
- Minerals (maintain health and regulate bodily functions)
Digestive Systems
- Monogastric: Single-chambered stomach (e.g., humans, pigs)
- Ruminant: Multi-chambered stomach (e.g., cows, sheep)
- Pseudo-ruminant: Modified multi-chambered stomach (e.g., hippopotamuses)
Nutrient Uptake and Absorption
- Mouth: Mechanical breakdown of food
- Stomach: Chemical breakdown of food by enzymes and acids
- Small Intestine: Nutrient absorption into bloodstream
- Large Intestine: Water absorption and waste formation
Feeding Behaviors
- Herbivory: Plant-based diet (e.g., cows, deer)
- Carnivory: Meat-based diet (e.g., lions, wolves)
- Omnivory: Mixed diet (e.g., humans, bears)
Nutritional Deficiencies and Disorders
- Malnutrition: Inadequate nutrient intake
- Deficiency diseases: Specific nutrient deficiencies (e.g., scurvy, rickets)
- Metabolic disorders: Impaired nutrient metabolism (e.g., diabetes, obesity)
Nutrition in Animals
Types of Nutrition
- Autotrophic Nutrition involves producing own food through photosynthesis, found in organisms like plants and algae.
- Heterotrophic Nutrition involves obtaining energy by consuming other organisms, found in organisms like animals and fungi.
Nutritional Requirements
Macronutrients
- Carbohydrates serve as an energy source.
- Proteins act as building blocks for growth and repair.
- Fats serve as an energy source and are necessary for hormone production.
Micronutrients
- Vitamins regulate metabolism and maintain health.
- Minerals are essential for maintaining health and regulating bodily functions.
Digestive Systems
- Monogastric digestive systems have a single-chambered stomach, found in organisms like humans and pigs.
- Ruminant digestive systems have a multi-chambered stomach, found in organisms like cows and sheep.
- Pseudo-ruminant digestive systems have a modified multi-chambered stomach, found in organisms like hippopotamuses.
Nutrient Uptake and Absorption
- In the mouth, food undergoes mechanical breakdown.
- In the stomach, food undergoes chemical breakdown by enzymes and acids.
- The small intestine is responsible for nutrient absorption into the bloodstream.
- The large intestine is responsible for water absorption and waste formation.
Feeding Behaviors
- Herbivory involves a plant-based diet, found in organisms like cows and deer.
- Carnivory involves a meat-based diet, found in organisms like lions and wolves.
- Omnivory involves a mixed diet, found in organisms like humans and bears.
Nutritional Deficiencies and Disorders
- Malnutrition occurs when there is an inadequate intake of nutrients.
- Deficiency diseases occur when there is a specific nutrient deficiency, such as scurvy or rickets.
- Metabolic disorders occur when there is an impaired nutrient metabolism, such as diabetes or obesity.
