Which are two ways that plants help humans have a clean environment? photosynthesis and cellular respiration
cellular respiration and preventing erosion
encouraging erosion and bioremediation
bioremediation and acting as a carbon sink

The correct answer is- bioremediation and acting as a carbon sink

Explanation:

Plants play various roles in affecting the environment. Plants prevent soil erosion, pulling carbon from the atmosphere by photosynthesis incorporating or releasing oxygen by cellular respiration, acts as pollution indicator, decreases soil toxicity, provides habitat and niche and many more to balance ecosystem and improve the environment.

Plants to help in cleaning the environment can be played by these two ways:

1. bioremediation in pants or phytoremediation is the process in which the roots system of plants uses synergistic action for the growth of microorganisms and removal of toxic substances from the soil.

2. plants also play the role as a carbon sink due to the ability to absorbs a huge amount of carbon from the environment and use it to produce food and energy and releases oxygen in this process.
