Analyze the indicator species

The question asks to identify an ecosystem featuring three specific indicator organisms: conifers (cone-bearing needle-leaved trees), lichens (composite organisms of algae/cyanobacteria and fungi), and deer (herbivorous mammals).

Evaluate the options based on ecological requirements

• A. desert of Australia: Deserts are characterized by extremely arid conditions. They lack conifers and deer, and are dominated by drought-resistant shrubs, grasses, and specialized fauna.
• B. low tundra of Canada: The tundra is a treeless biome characterized by permafrost. While lichens are abundant, conifers cannot grow here due to the extreme cold and frozen soil.
• C. rainforests of Brazil: Tropical rainforests are dominated by broadleaf evergreen trees, vines, and epiphytes. They do not typically feature conifers or temperate deer species.
• D. temperate forests of Russia: Temperate forests (including mixed and coniferous taiga-transition forests) in Russia are characterized by cold-to-mild climates where conifers (like pines, firs, and spruces) thrive, lichens grow on trees and rocks, and various deer species (such as red deer, roe deer, and musk deer) are common.
