The four kingdoms of Eukarya are:
- Protista: This kingdom includes a diverse group of organisms, such as algae, protozoa, and slime molds. They are mostly unicellular but can also be multicellular.
- Fungi: This kingdom consists of organisms like mushrooms, yeasts, and molds. Fungi are primarily decomposers and play a crucial role in nutrient cycling.
- Plantae: This kingdom includes all plants, from mosses and ferns to flowering plants and trees. Plants are autotrophic, meaning they produce their own food through photosynthesis.
- Animalia: This kingdom encompasses all animals, from insects and fish to birds and mammals. Animals are heterotrophic, meaning they obtain their food by consuming other organisms.
These four kingdoms represent the major groups of eukaryotic organisms, each with distinct characteristics and roles in the ecosystem.
