Presentation transcript:

Autotrophs vs. Heterotrophs

Autotrophs Organisms that make (synthesize) their own food through the process of photosynthesis use the energy in sunlight to convert water and carbon dioxide into Glucose (food) Autotrophs are also called producers Without autotrophs, there would be no life on this planet

Examples of Autotrophs All plants Algae Cyanobacteria

Autotrophs

Heterotrophs Organisms that do not make their own food Heterotrophs are also called consumers because they consume other organisms in order to live Examples: wolves, deer and humans

Heterotrophs

Types of Consumers Consumers are broken down into 4 main groups 1. Scavenger 2. Herbivore 3. Carnivore 4. Omnivore

Types of Consumer Scavengers/Detritivores – feed on the tissue of dead organisms (both plants and animals) Ex. – Vultures, Crows, and Shrimp

Types of Consumer Herbivores – eat ONLY plants Ex. – Cows, Elephants, Giraffes

Types of Consumer Carnivores – eat ONLY meat Ex. – Lions, Wolves, Sharks

Type of Consumer Omnivores – eat BOTH plants and animals Ex. – Bears and Humans
