<span>ecosystems
</span>An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system. <span> </span>

an independent variable is a variable that we choose to change to see that happens. ( eg. the temperature when testing evaporation).
a dependent variable is the variable that we measure. ( so maybe how much water evaporates)
