Question

what is the main way that humans are disrupting the carbon cycle? growing crops, which causes too much photosynthesis, causing an imbalance in the cycle burning fossil fuels, which puts carbon into the atmosphere at a much faster rate than normal, leading to warming. using fertilizers, which increases nutrient availability in ecosystems, leading to eutrophication we are respiring too much, and it is putting too much co2 in the atmosphere. clear my selection 1 point

Explanation:

The carbon cycle is disrupted mainly by burning fossil fuels. Fossil - fuel combustion releases large amounts of carbon dioxide into the atmosphere at a much faster rate than natural processes can handle, leading to an imbalance in the carbon cycle and contributing to global warming. Growing crops doesn't directly disrupt the carbon cycle in the same significant way as fossil - fuel burning. Using fertilizers mainly causes eutrophication issues related to nutrient availability in ecosystems, not a major disruption to the carbon cycle. Human respiration is a natural process and does not cause a significant imbalance in the carbon cycle compared to fossil - fuel burning.

Answer:

Burning fossil fuels, which puts carbon into the atmosphere at a much faster rate than normal, leading to warming.
