1. Using the data provided, draw a pyramid of productivity.2. What are the units for productivity? – include them3. What does productivity represent in organisms?4. How much energy passes from one trophic level to the next?

Learning outcomes
You should all be able to:• Define gross productivity, net productivity, primary
productivity and secondary productivity
Most of you should be able to:• Calculate the values of gross and net productivity from
given data

What is productivity?
Thinking about ecosystems – how do you think we measure productivity?

There are two types of productivity
Primary Secondary
What do you think the difference is?
Discuss it with a partner now write down your idea on the sheet

Primary Productivity - plants• Conversion of solar energy
Carbon dioxide from the atmosphere
Water from the soil
Oxygen released
Sunlight
![Page 6: Starter Trophic LevelProductivity (units?) Producers5000 Primary consumers500 Secondary consumers50 Tertiary consumers5 1.Using the data provided, draw.](https://reader035.fdocuments.us/reader035/viewer/2022062311/5a4d1b147f8b9ab059990d7f/html5/thumbnails/6.jpg)
What factors affect primary productivity?
• Amount of sunlight• Availability of factors needed for growth• Levels of insolation• Supply of water• Temperature• Nutrient levels• Efficiency of producers

Secondary Productivity - animals
![Page 8: Starter Trophic LevelProductivity (units?) Producers5000 Primary consumers500 Secondary consumers50 Tertiary consumers5 1.Using the data provided, draw.](https://reader035.fdocuments.us/reader035/viewer/2022062311/5a4d1b147f8b9ab059990d7f/html5/thumbnails/8.jpg)
These two types can be divided…
Gross productivity Net productivity
What do you think the difference is?
• Gross productivity is the total gain in energy or biomass per unit area per unit time
• Net productivity is the remaining energy that is available to the next trophic level.

1. What does NPP stand for?
2. What does it mean?
3. How would you calculate it?
4. What about GSP?
