Answer: c. birds eating seeds from plants
Explanation:
A fruit tree is a tree which bears fruitthat is consumed or used by humans and some animals — all trees that are flowering plants produce fruit, which are the ripened ovaries of flowers containing one or more seeds. In horticultural usage, the term 'fruit tree' is limited to those that provide fruit for human food.
When caused by humans, acid rain is most commonly a byproduct of intense air pollution. As pollutants are pumped into the atmosphere, the particles rise up to the point where water can condense around them thereby forming water vapor and rain drops; however, those rain drops are closely intertwined with the pollutants thereby giving them an acidic nature.
Africa and South America's coastlines fit well together
Condensation is when water vapour (a gas) turns into a liquid. This can be obverved on the outside of a glass and is also the process which forms clouds. If you yourself can observe condensation, it must be in the bottom layer of the atmosphere, the troposphere.
