(environmental science) 1.which aspects of climate are most important to forest ecosystems?

Probably the CO2 concentration. If the earth gets warmer by rising greenhouse gases (one of which is CO2), the amount of rainfall and precipitation increases. I am not an expert, but that's my first guess.

Carbon Dioxide would be your answer. Plants love Carbon Dioxide and as a gift they produce oxygen, its also because of greenhouse effects because of the sun and gases around. However, the amount of Carbon Dioxide on our planet Earth is running low so soon Earth's landscapes will soon decay.

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
