What is tropical forest ecosystem?

The tropical rainforest biome has four main characteristics: very high annual rainfall, high average temperatures, nutrient-poor soil, and high levels of biodiversity (species richness). Rainfall: The word “rainforest” implies that these are the some of the world's wettest ecosystems.

Is Tropical Rainforest soil fertile?

Most tropical rainforest soils relatively poor in nutrients. ... More recent volcanic soils, however, can be very fertile. Tropical rain forest soils contain less organic matter than temperate forests and most of the available nutrients are found in the living plant and animal material.

What soil is black?

Soil color is produced by the minerals present and by the organic matter content. Yellow or red soil indicates the presence of oxidized ferric iron oxides. Dark brown or black color in soil indicates that the soil has a high organic matter content. Wet soil will appear darker than dry soil.

Why is my soil turning GREY?

Grayish soils, therefore, are found in areas with high levels of both moisture and iron. If a gray soil has a bluish or greenish cast, that may indicate the presence of sulfur.
