As kingdom grows the more species are in the classifying group.
And since there are only a number of kingdom and thousand species, it would account that species changes more rapidly and exponentially grows than kingdoms.

Copernicus gave heliocentric theory which changed the view about the solar system people had till that time.
Explanation:
Nicolaus Copernicus is known to have given the heliocentric theory about the solar system. This theory formulated that the Earth revolves around the Sun. It also comes up with the fact of rotation of Earth around its own axis.
Before the ideology of Copernicus came into being, Ptolemy gave his ideology and all the people believed in it truly as it said that the Earth is in the center of all the planetary object and every planet revolves around it. This theory came to an end by the Copernicus findings.

Answer: Still adds carbon dioxide to the atmosphere, Can have gas leaks which are a safety hazard because it is colorless and odorless, It is dangerous if directly inhaled
Explanation:
Final answer:
Natural gas, despite being the cleanest of the fossil fuels, has some associated problems. It still adds carbon dioxide to the atmosphere, can have gas leaks which are a safety hazard, and is dangerous if directly inhaled.
Explanation:
Natural gas, while considered the cleanest of the fossil fuels, still has some problems associated with its use:
- It still adds carbon dioxide to the atmosphere: Like other fossil fuels, natural gas releases carbon dioxide when burned, contributing to climate change.
- It can have gas leaks which are a safety hazard: Natural gas is colorless and odorless, making it difficult to detect. Leaks can lead to fire or explosions, posing a safety risk.
- It is dangerous if directly inhaled: Inhaling natural gas can lead to asphyxiation, which can be harmful or even fatal.

Final answer:
Areas around the equator tend to have higher concentrations of chlorophyll due to the abundance of direct and intense sunlight they receive. Competition for light in equatorial regions, such as rainforests, also plays a role in the adaptation of plants to low light levels. These factors contribute to the observed distribution of chlorophyll.
Explanation:
Areas around the equator tend to have higher concentrations of chlorophyll because of the amount of sunlight they receive. The equator receives more direct sunlight throughout the year compared to other regions, resulting in higher intensity and duration of sunlight. This abundance of sunlight provides ample energy for photosynthesis, leading to increased chlorophyll production in plants and algae.
In addition, the competition for light in equatorial regions is intense, particularly in dense plant communities like rainforests. Taller trees can block a significant portion of sunlight, creating shaded areas closer to the forest floor. In response, plants on the rainforest floor have adapted to low light levels by changing the relative concentrations of their chlorophyll pigments, allowing them to absorb any available light more efficiently.
These factors contribute to the higher concentrations of chlorophyll observed around the equator, as the availability and intensity of sunlight promote the growth and photosynthetic activity of plants and algae.
