Need help with question 23. Which is an appropriate conclusion for the data shown?

The decrease in carbon dioxide (CO2) for the leaf was less than the decrease for the stem.

- More oxygen was produced in the stem than in the leaf.

-There was no photosynthesis taking place in the roots.

- The stem was performing photosynthesis at a faster rate than the leaf.

I think Its the stem was performing photosynthesis at a faster rate than the leaf. But I'm not 100% sure, but I think its that one. I hope this helped!

frogs. the lower the ph the higher the acid content. frogs have the highest tolerance in this scenario.

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
