Verified step by step guidance1
Identify the key factors that influence net productivity and biomass in ecosystems, such as availability of water, temperature, and biodiversity.
Understand that net productivity refers to the rate at which plants in an ecosystem produce net useful chemical energy, while biomass is the total mass of living organisms in a given area.
Recognize that water availability is a crucial factor for plant growth and photosynthesis, which directly affects net productivity and biomass.
Consider the environmental conditions of deserts, which are characterized by extreme temperatures and very low precipitation, leading to limited water availability.
Compare these conditions with those of tropical rainforests and savannas, which have abundant rainfall and more stable temperatures, supporting higher biodiversity and greater net productivity and biomass.
