Question

which of the following are ways humans contribute to the release of excess carbon dioxide in earth’s atmosphere? select two correct answers. a by allowing cattle to graze b by burning fossil fuels c by cultivating rice d by cutting down large number of trees

Explanation:

Burning fossil fuels releases carbon - stored for millions of years as carbon dioxide. Cutting down trees reduces the number of plants that absorb carbon dioxide through photosynthesis. Cattle grazing and rice cultivation contribute to other greenhouse - gas emissions (like methane) rather than significant carbon - dioxide release in the context of this question.

Answer:

B. by burning fossil fuels
D. by cutting down large number of trees
