The nutrient is phosphorus
<h3>The phosphorus cycle</h3>
Phosphorus cycles between living components of the earth (biosphere) and the soil (geosphere).
The element's reservoir is mainly the sediments of the ocean and rocks. Phosphorus gets into the soil by weathering of rocks.
Plants are able to pick the element up from the soil and animals are able to get their phosphorus by consuming plants.
When plants and animal die, their body decomposes and the phosphorus in them enters the soil.
Thus, the cycle being referred to in the illustration is the phosphorus cycle.

<h2> Ecological Footprint</h2>
The ecological footprint is an indicator that accounts for human demand on global biological resources. If a person observed his ecological footprint, there will be less environmental problems like carbon emissions, lack of fresh air, global warming and increased environmental pollution would be reduced.
<h3>Impact of ecological footprint</h3>
One of the four categories of ecological footprint can serve as an environmental indicator because the category causes impact on the environment which leads to change in the environment so we can conclude that the category of ecological footprint can serve as an environmental indicator.
