All sources of pollution do not come from human activities.
<h3>What are the causes of pollution?</h3>
There are some natural causes of pollution. When dangerous pollutants enter the air as gases, liquids, or solids, air pollution is formed. Although there are some natural processes that can produce air pollution, such as sulfur and chlorine gases from volcanic activity, smoke and ash from wildfires, dust storms, and biological degradation, manmade sources account for the majority of pollution in the atmosphere.
Burning fossil fuels for transportation, energy, and industry produces the majority of air pollution that is caused by humans. Carbon dioxide, nitrogen oxides, sulfur dioxide, volatile organic compounds (VOCs), and particulates are typical pollutants released by fossil fuel-burning engines. In addition to particles, carbon monoxide and carbon dioxide are produced by stoves, incinerators, and open burning.

Konichiwa~! My name is Zalgo and I am here to help you out on this amazing day. According to my knowledge and evidence, I would say that the bush is very well alive. It grows, it provides you an element that you need to survive, and if you cut it down to a size you like, all it will do is grow back up.
I hope that this info helps! :D

Answer:
If there wasn't a lot of organisms and energy in the productive part of the triangle, then there wouldn't be a lot of third level organisms. The energy piramid would be a lot smaller then what it is here, and maybe if the energy source was low then there might not be such a vast varity of animals in the ecosystem.
You're welcome friend <3
