The two biomes which have moderate precipitation levels are savanna and grassland.
Step-by-step explanation:
An ecosystem includes both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which associates as a system. More importantly, the living things are very modified in the abiotic community because it cannot sustain by itself. Every animal, plant and human needs the primary physiological needs of water, food, and shelter provided by the abiotic system.
A biome is formed of several diverging ecosystems that relate to the community. Biomes can each be deserts, grassland, savanna, tropical rain forest, taiga, boreal and etc.
