Final answer:
Biocapacity can decrease due to factors such as overexploitation of resources, pollution, habitat destruction, and climate change. These factors reduce the availability of essential resources, impacting the carrying capacity of ecosystems.
Step-by-step explanation:
Biocapacity can decrease due to various factors, such as overexploitation of natural resources, pollution, habitat destruction, and climate change. These factors can lead to a decline in the availability of essential resources for organisms, which in turn reduces the carrying capacity of ecosystems.
For example, deforestation reduces the amount of available land for plants and animals to thrive and reduces the oxygen production that forests provide. Pollution from industrial activities can contaminate water bodies and diminish the suitability of the environment for aquatic organisms. Climate change can disrupt the balance of ecosystems, impacting the distribution and availability of resources for different species.
In summary, human activities and environmental changes can cause biocapacity to decrease, affecting the ability of ecosystems to support life.
