🦁 Lesson 5: What Do Animals Eat? (Animal Feeding Habits)

Learning Objectives:

• To classify animals by their feeding habits (herbivore/carnivore/omnivore).

Classification:

Humans are naturally omnivores.

Quick Reference:

🌱 Sprouted Seeds & Honey

• Sprouted Seeds: When seeds start to germinate (grow a white shoot) after soaking in water, they are called sprouts. They are more nutritious. (Examples: Moong, chana).

• Honey: Bees collect nectar from flowers, bring it to their hive, and convert it into honey.

📝 Key Definitions

• Ingredients 🥣: Materials used to make food.

• Herbivores 🐮: Animals that eat only plants.

• Carnivores 🦁: Animals that eat only other animals.

• Omnivores 🐻: Animals that eat both plants and animals.

• Edible 🍏: Fit to be eaten.

• Nectar 🌺: Sweet liquid in flowers collected by bees.

• Sprouted Seeds 🌱: Seeds that have just started to grow.
