Question

question 26 (1 point) excess co₂ in the atmosphere contributes most directly to: a weathering b nitrogen fixation c eutrophication d climate change question 27 (1 point) when oceans absorb co₂, this improves biodiversity of life on land and in water. true false

Explanation:

For Question 26, carbon - dioxide is a greenhouse gas. Excess of it in the atmosphere traps heat, causing climate change. Weathering is related to the breakdown of rocks, nitrogen fixation is about converting nitrogen gas to usable forms, and eutrophication is mainly due to an excess of nutrients like nitrogen and phosphorus. For Question 27, when oceans absorb CO₂, it leads to ocean acidification which harms marine life and biodiversity, not improves it.

Answer:

Question 26: d. Climate change
Question 27: False
