Question

Coral reefs have higher primary productivity than temperate forests. What does that mean?

Answer 1

There is a larger total number of species in a coral reef than in a temperate forest.

Answer 2

Answer:

The autotrophs of coral reefs produce more chemical energy per unit time as compared to the producers of temperate forests.

Explanation:

Primary productivity refers to the total of the sunlight energy that is converted into chemical energy of the organic compounds by autotrophs over a given period.

The statement means that the producers of the coral reefs produce more chemical energy per unit time than the chemical energy produced by producers/autotrophs of the temperate forests.
