🔑Concepts
Domestic Animals: Animals that are tamed and kept by humans for work, food, or companionship. They are divided into Pet animals (like dogs and cats) and Farm animals (like cows, sheep, and hens).
Wild Animals: Animals that live in their natural habitats such as forests, grasslands, or oceans without human intervention. Examples include lions, tigers, and giraffes.
Feeding Habits: Animals are classified based on what they eat: Herbivores (plants only), Carnivores (flesh only), and Omnivores (both plants and flesh).
Scavengers: Animals like vultures and hyenas that eat the flesh of dead animals, helping to keep the environment clean.
Shelters: Domestic animals live in man-made shelters (e.g., horses in a 'stable', cows in a 'shed'), while wild animals find or build natural shelters (e.g., lions in a 'den', birds in 'nests', rabbits in 'burrows').
Breathing: Like humans, animals breathe. Most land animals take in oxygen () and release carbon dioxide () through their lungs.
