Plants are the organisms that produce oxygen, or O2. To do this, they go through a process called photosynthesis. They take carbon dioxide, water, and sunlight, and convert it into oxygen and glucose (sugar). Without plants, you, me, your pet, and all other living organisms wouldn't have oxygen :) hope this helped!

Human decisions about controlling erosion have very little effect on living conditions.
Vika [28.1K]

Answer:

False

Explanation:

The main cause of man-made erosion is agriculture, followed by construction and mining.

Where humans once used sticks and stones, they have since developed technology that dramatically accelerated the speed of erosio.

Hence, if human descions are to control the soil erosion then there will be a very big impact on living conditions.
