Study Notes

Autotrophs and Heterotrophs

Autotrophs create their own energy, mainly through photosynthesis or chemosynthesis.
Heterotrophs rely on consuming other organisms for energy and nutrients.

Types of Autotrophs

Photoautotrophs: Use sunlight to perform photosynthesis, converting light energy into chemical energy (glucose).
Chemoautotrophs: Utilize chemical reactions to convert inorganic compounds into glucose through chemosynthesis.

Nutritional Categories

Consumers: Organisms that obtain nutrients by eating other living beings.
Decomposers: Break down dead organisms, recycling nutrients back into the ecosystem.

Specific Dietary Types

Herbivores: Organisms that exclusively consume plants for their nutritional needs.
Carnivores: Organisms that primarily eat meat, relying on other animals for energy.
Omnivores: Flexible eaters who consume both plants and animals, taking advantage of diverse food sources.
