The correct answer is D. Pioneer species
Explanation:
In biology, the term "pioneer species" refer to the first species that colonize new environments or environments in which there is no biodiversity for example lands that have been affected by fire, lava, etc. These species are in most cases plants or small organism that are resistant and able to adapt to the harsh conditions of new land. Additionally, this concept differs from keystone and foundation species because these two concepts describe species that have an important role in the ecosystem rather than those that first live on new land. Therefore, the first species to live on new land are the pioneer species.
<u>Question</u>:
Which activity produces the smallest amount of greenhouse gases?
a. driving a car
b. riding a bicycle
c. cooking with gas
d. operating a generator
<u>Answer</u>:
Riding a bicycle produces the smallest amount of greenhouse gases
<u>Explanation</u>:
Cars and other heavy vehicles account for approximately 1/5th of the United States emissions, producing carbon dioxide and other greenhouse gases such as methane and nitrous oxide. Cooking gas too produces a lot of carbon dioxide. Natural gas too basically consists methane in an odourless form and therefore when released produces greenhouse effects and in turn causes detrimental effects on the environment.
The generators that are used both at low scale and also in high level industries is known to produce toxic levels of carbon monoxide and methane. Compared to all these, a bicycle which produces greenhouse gases during its production does not release as much greenhouse gases and the rest.
