Why is satellite imagery useful to ecologists (mark all the apply)? small habitats can be observed individual high resolution of ecosystems is possible large-scale regional studies of biomes can be mapped all vegetation types of ecosystems can be identified the predominant vegetation of an ecosystem can be monitored the fauna of an ecosystem can be counted natural disasters can be surveyed all natural factors can be identified outstanding environmental factors can be monitored

Large-scale regional studies of biomes can be mapped.

The predominant vegetation of an ecosystem can be monitored.

Natural disasters can be surveyed.

Outstanding environmental factors can be monitored.

it has one origin of replication, but it proceeds in two directions - d)

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.
