Introduction to the animal kingdom, including classification, characteristics, and diversity of species.

Classification of animals into vertebrates (reptiles, birds, mammals, amphibians, fish) and invertebrates (over 20 phyla).

Overview of the total number of animal species and the ones identified, emphasizing the vast diversity.

Discussion on evolution through natural selection and the meaning of the term 'animalis', highlighting multicellularity and heterotrophy.

Explanation of animal cells being microscopic and forming the basis of multicellular organisms.

Description of animal development processes, using the example of butterflies, and their initial stages.

Explanation of animals' inability to produce their own food and the presence of a mouth for feeding.

Discussion on active and passive feeding behaviors in animals, with examples like whales filtering water.

Overview of different methods of gas exchange in animals and the need for breathing to live.

Explanation of different breathing mechanisms in animals, including cutaneous, branchial, and pulmonary systems.

Description of sensory systems in animals and their responses to stimuli for survival and adaptation.

Explanation of animal movements, classification into vertebrates and invertebrates, and support structures like the backbone.

Overview of vertebrate groups (fish, mammals, birds, reptiles, amphibians) and their distinguishing characteristics.

Characteristics and examples of each vertebrate group like fish breathing with gills, mammals being warm-blooded, birds being oviparous, and reptiles adapting to different environments.

Details on amphibians and invertebrates, their habitats, reproductive features, and bodily structures.

Explanation of sexual and asexual reproduction, with examples like sharks and armadillos, and mechanisms like fragmentation and budding.

Discussion on asexual reproduction methods like budding, fission, and parthenogenesis, including genetic diversity aspects.

Explanation of sexual reproduction processes like gamete production, fertilization, and zygote formation in animals.

Overview of animal dietary habits, including carnivores, herbivores, and omnivores, with examples of each.
