How do you measure temperature and what is the effect of it on living organisms.
Thermometer or probe. In low temperatures metabolism slow right down. This reduces the activities of animals that can't regulate their body temperatures.

How do you measure nutrients and what is the effect of it on living organisms.
Chemical analysis. Plants and microorganisms need ion to produce chemicals essential for living processes, so plants don't grow well in nutrient-poor soil

How do you measure the amount of light and what is the effect of it on living organisms.
Light meter or light sensor. Plants need light for photosynthesis, so only specialised plants can grow well in shade conditions.

What is the effect of the availability of water on living organisms.
Most living organisms contain a very high proportion of water which is essential for all processes.

How do you measure the availability of oxygen in water or soil and what is the effect of it on living organisms.
Oxygen electrode. Oxygen is essential for aerobic respiration, so only specialised animals can live in water which with a low concentration of dissolved oxygen.

How do you measure the availability of carbon dioxide and what is the effect of it on living organisms.
Gas analysis. Carbon dioxide is essential for photosynthesis and may be a limiting factor in some circumstances.
