Question

what is the main reason why raising cattle contributes to global warming? (1 point)
cattle have microbes in their stomach that produce methane during digestion.
cattle store nitrogen, which is released as nitrous oxide as they die.
cattle release carbon dioxide as they breathe, similar to humans.
cattle eat grass, which reduces the amount of plants that remove atmospheric carbon dioxide.

Explanation:

Methane is a potent greenhouse - gas. Cattle have anaerobic microbes in their rumen (a part of the stomach) that produce methane during digestion. This methane is released into the atmosphere and contributes significantly to global warming. Nitrous oxide release upon death is not the main contributor. Carbon - dioxide release during breathing is a normal process and not the main reason for cattle's contribution to global warming. While cattle eating grass can affect plant - based carbon sequestration, it is not the primary factor compared to methane production.

Answer:

Cattle have microbes in their stomach that produce methane during digestion.
