Why might it eventually be a problem for sporangia to continually reproduce and grow in the same pile of manure?

If sporangia continually reproduce and grow in the same pile of manure, it could lead to nutrient depletion as they consume available resources, ultimately hindering their growth and reproduction. Additionally, the accumulation of waste products from their metabolic processes could create an inhospitable environment, potentially fostering the growth of harmful pathogens or competing organisms. This overpopulation could also result in increased competition among sporangia, reducing overall viability and genetic diversity within the population.
