Would you expect to see more biodiversity among members of a phyla or among members of a class? why?

Phylum

Explanation:

The phylum would have more number of species as compared to that of class. This is because according to classification phylum is bigger than class.

This means that many many different classes can come under phylum but a phyla cannot come under class.

So, the phylum has diversity of organism in it. At hierarchical level the organism belonging to phylum are at higher level and organism belonging to class are at lower levels.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
