The pie charts show the nutrient levels in two biomes. (a) Compare and contrast the nutrient stores in taiga and tropical rainforest.

Tropical rainforests are found at, or close to, the equator. Direct sunlight rays heat the Earth’s surface and drive a continual cycle of evaporation and precipitation,soil, it can be surprisingly nutrient-poor,where taiga is nutrient rich soil.

The pie charts show the nutrient levels in two biomes. Describe the flow of nutrients in taiga.

Taiga is the Largest terrestrial biome, but the diversity of its plant and animal life is much Lower, consisting of large mammals and coniferous trees. Because the rainforest is so diverse, the amount of predators and prey ensure that there are many trophic levels. Consumers like monkeys can also be secondary consumers and in turn be consumed by tertiary consumers. Taiga does not have as many levels or such complex food webs due to the lesser amount of species. Taiga is drier, the temperature is cooler as most taiga are near or in the mountains, and there is heavy snowfall but not as much precipitation,

The pie charts show the nutrient levels in two biomes. (c) Draw a Gersmehl diagram for the tropical rainforest.

Gersmehl diagrams are models of the inter-relationships between nutrient stores and flows between biomass, litter and soil. The diameter of the circles is an indication of the amounts stored, the width of the arrows gives an indication of amounts flowing and the arrow shows the direction of the flow.

The pie charts show the nutrient levels in two biomes. (d) Suggest one reason the nutrient store above the ground is so high in both biomes.

The majority nutrition is in form of trees and animals.
