Document Summary
Productivity = the rate at which plants produce biomass. Varies from warm to cold climates, and from wet to dry environments. Resilience = the ability to recover from disturbance. There are 9 major biome types, which can be further divided into smaller classes: many temperature controlled biomes occur in latitudinal bands. E. g. , tropical forests occur near the equator. E. g. , expansive grasslands occur near or beyond the tropics: some biomes are named for their latitudes. E. g. , tropical rainforests occur between tropic of cancer and tropic of capricorn. E. g. , arctic tundra lies near or above the arctic circle (cid:173) Tropical moist forests are warm and wet year-round. Soil tends to be thin, acidic, and nutrient-poor: about 90% of all the nutrients are contained in the bodies of the living organisms, rapid decomposition, recycling, and incorporation of dead organic material immediately back into living biomass.
