Heterotrophs:
* Definition: Animals that cannot produce their own food through photosynthesis. They must obtain organic matter by consuming other organisms.
* Key Characteristics:
* Consumers: They rely on consuming plants (herbivores), animals (carnivores), or both (omnivores) for energy.
* Metabolic Dependence: They break down the complex molecules of their food to obtain energy and building blocks for growth.
* Diverse Feeding Strategies: They can have highly specialized feeding mechanisms and diets, from scavenging to hunting.
Examples of Heterotrophs:
* Herbivores: Cows, rabbits, deer, caterpillars
* Carnivores: Lions, sharks, owls, spiders
* Omnivores: Humans, bears, raccoons, pigs
* Parasites: Tapeworms, fleas, ticks
In short, heterotrophic animals are those who can't make their own food and must "eat" to survive. They are the consumers in the food chain, driving energy flow by consuming other organisms.
