Study Notes
Nutrition in Living Organisms
- Autotrophic nutrition is exemplified by plants, which synthesize their own food using sunlight, water, and carbon dioxide.
Importance of Nutrition
- The primary function of nutrition in living organisms is to provide energy, build and repair tissues, and regulate various bodily functions.
Role of Vitamins
- Vitamins are essential nutrients that facilitate various metabolic processes, including energy production, immune function, and cell growth.
Holozoic Nutrition
- A characteristic of holozoic nutrition is the ingestion of solid food particles, which is seen in animals that consume other organisms or plants.
Saprophytic Nutrition
- The primary function of saprophytic nutrition in an ecosystem is to decompose organic matter, releasing nutrients back into the environment.
Parasitic Nutrition
- A characteristic of parasitic nutrition is that one organism, the parasite, obtains its nutrients by feeding on another organism, the host, often causing harm.
