Look at the rainfall graph over an 11 year period of lower than average rainfall in this ecosystem, predict how the biotic factors within this ecosystem would respond. Make sure to describe how eventually all trophic levels would be affected.

The ecosystem is represented by the climatograph below. The Gross Primary Productivity (GPP) is measured to be 5000 grams of carbon per square meter per year, and the Total Respiration (RT) is measured to be 300 grams of carbon per square meter per year. - What kind of biome is this? - Calculate the Net Ecosystem Production (NEP) for this ecosystem - What does the calculated NEP value indicate about the carbon balance and overall productivity of the ecosystem? (one sentence) - Based on both the climatograph and the NEP, what can you say about the biodiversity of plants versus consumers?

Examine the model and the relationships between the major players (i.e., predator, prey, producer). The structure's most important role is played by these major players. It's also worth noting that nutrition has been included in the model. This is the abiotic component that has a direct or indirect impact on the interaction.
