TaigaAbiotic factors
Winters are long and cold
Averages 100 in/yr precipitation—mostly snow
Soil poor in nutrients and very acidic
Growing season is very short

Tropical Rainforest Abiotic factors high biodiversity and
biomass
both hot and moist;
ideal for bacteria and other microorganisms; they quickly decompose matter on the forest floor allowing nutrients to be recycled.
<1 cm of topsoil
About 100 in/yr of rainfall

Threats to the Coral Reefs
Temperature is important, too hot or too cold and the animals can not survive.
Human intrusion (scuba diving) is damaging if you touch/step on the reef
Pollution is also a concern.

Open ocean is one of the least productive areas on earth, too little sunlight to support plant growth
Covers nearly ¾ of the Earth’s surface.
