# using dry mass to measure rate of photosynthesis? Watch

1. I don't understand , how could you use this to measure.
2. Sorry you've not had any responses about this. Are you sure you've posted in the right place? Here's a link to our subject forum which should help get you more responses if you post there.

You can also find the Exam Thread list for A-levels here and GCSE here.

Net productivity = gross productivity - respiratory loss

So gross productivity must be high, this is the rate at which the plant photosynthesises to produce organic matter. Net productivity is the amount of dry mass available to primary consumers - use the equation to calculate dry mass in relation to photosynthesis.
