Answer :
Answer:
II. Global warming may cause drought conditions in some areas, which would limit the amount of water available to plants in those areas.
III. Global warming may cause severe flooding in some areas, which could inhibit photosynthesis if a plant's leaves and stems are submerged.
Explanation:
Global warming is one of the effects of climate change. It is simply the warming of the surface of the earth as result of increase in temperature on the earth surface.
Global warming results from increase in levels of greenhouse gases in the earth's atmosphere. These gases prevents radiation from leaving the earth surface thereby leading to increase in temperature. The more the gases, the more the spike in temperature.
This increase in temperature can lead to drought.
As the earth also warms, polar ice can melt which can increase the level of water in the world's oceans and then flooding of coastal areas.
Answer is II and III
Explanation - Global warming is an increase in the surface air temperature of the Earth. Human activities such as the burning of fossil fuels are contributing to a current episode of global warming. Many scientists predict that current global warming will cause an increase in extreme weather conditions, such as flooding and drought.
Drought conditions limit the amount of water available to plants. Plants cannot live without sufficient water. On the other hand, too much water can cause excessive flooding, which can inhibit photosynthesis in plants if a plant's leaves and stems are submerged.
Increasing CO2 levels and increasing growing seasons are both positive effects that global warming could have on plant life on Earth.
