For What Purpose Would a Microbial Ecologist Use a Microsensor

Question

For what purpose would a microbial ecologist use a microsensor?
A) to determine the concentration of cells in small increments in a sediment or water column
B) to determine the expression of a particular gene in a microbial community
C) to quantify the uptake of a radioactive material
D) to determine the concentration of O₂, N₂O, or other chemical species in small increments in a sediment or water column

Accepted Answer

Microsensors can be used to determine the concentration of specific chemical species in small increments in a sediment or water column. This can be useful for microbial ecologists to study the microbial activity and metabolism in different environments. For example, measuring the concentration of oxygen or other chemical species can help to understand the nutrient cycles and energy flow in an ecosystem.
