Here's the completed table, based on general knowledge about Earth's natural zones:
| Natural Zones | Natural Conditions | Plant World | Animal World |
|---|---|---|---|
| Moist equatorial forests | High temperature, high humidity, abundant rainfall throughout the year. | Dense, multi-layered vegetation: tall trees, lianas, epiphytes, ferns. High biodiversity. | Monkeys, parrots, snakes, jaguars, insects, amphibians. High species diversity. |
| Deserts | Very low rainfall, high temperatures during the day, low at night, strong winds. | Sparse vegetation: succulents (cacti), drought-resistant shrubs, ephemeral plants that bloom after rain. | Camels, lizards, snakes, scorpions, rodents, birds of prey. Adapted to arid conditions. |
| Steppes | Moderate rainfall, hot summers, cold winters, fertile soils (chernozems). | Grasses, herbaceous plants, few trees (mainly along rivers). | Hoofed animals (saiga, horses), rodents (marmots, gophers), predators (foxes, wolves), birds (bustards, eagles). |
| Mixed and deciduous forests | Moderate rainfall, distinct seasons (warm summers, cold winters). | Deciduous trees (oak, maple, birch) and conifers (pine, spruce). Undergrowth of shrubs and grasses. | Deer, wild boars, squirrels, foxes, wolves, bears, various birds. |
| Taiga | Cold climate, long winters, short cool summers, high humidity, acidic soils. | Coniferous forests (spruce, pine, fir, larch). Mosses and lichens on the ground. | Moose, bears, wolves, lynx, foxes, squirrels, birds (woodpeckers, owls). Fur-bearing animals. |
| Tundra | Very cold climate, permafrost, short cool summers, strong winds, low precipitation. | Low-growing vegetation: mosses, lichens, dwarf shrubs, grasses, sedges. No trees. | Reindeer, arctic foxes, polar bears, lemmings, arctic hares, migratory birds. |
| Arctic desert | Extremely cold, ice and snow cover, very little precipitation, short polar summer. | Virtually no vegetation, only some mosses and lichens on rocky outcrops. | Polar bears, arctic foxes, seals, walruses, penguins (in Antarctic). Marine life is abundant. |
