Approximately 90 naturally occurring elements have been found in nature.
Elements are the fundamental building blocks of matter, and they cannot be broken down into simpler substances by chemical means. As of my knowledge cutoff in September 2021, there are 118 known elements in total, with 94 of them being naturally occurring or stable elements. Out of these naturally occurring elements, some are relatively abundant in the Earth's crust and are essential for life, while others are rare and occur in trace amounts.
The most abundant elements in the Earth's crust are oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium. These elements make up the vast majority of the minerals and rocks that form the Earth's surface.
Some elements, like carbon, hydrogen, nitrogen, and oxygen, are essential for life and are the building blocks of organic compounds, such as carbohydrates, proteins, lipids, and nucleic acids. These elements play a crucial role in the biochemistry of all living organisms.
On the other hand, there are elements that are extremely rare and occur in trace amounts, such as gold, platinum, and iridium. These elements have unique properties and are often valued for their scarcity and various industrial applications.
Elements can be found naturally in various forms, including minerals, ores, gases, and dissolved in water bodies. The study of elements and their properties is central to chemistry, physics, geology, and many other scientific disciplines, as it helps us understand the composition of the Earth, the universe, and the chemical processes that govern our world.

B. Secondary succession begins on soil and primary succession begins on newly exposed surfaces.
C. Primary succession modifies the environment and secondary succession does not.
D. Secondary succession begins with lichens and primary succession begins with trees.
Answer:
B. Secondary succession begins on soil and primary succession begins on newly exposed surfaces.
Explanation:
Succession is the natural development of a series of biotic communities at the same site. There are two types of succession; primary and secondary.
Primary succession occurs on lifeless unoccupied areas while secondary happens right after that and in there soil and some organism is present already.
I hope this answer helps you.
B through the process of respiration in these organisms
C through death and decomposition
D through the microbial process of ammonification
E through chemical reactions in acidifying oceans
Carbon locked in shells of marine organisms moves back to the atmosphere through death and decomposition of those organisms.
The carbon cycle refers to the movement of carbon through the biogeochemical cycle. The carbon cycle cuts across;

Answer:Sexual reproduction provides a more genetic diversity
Explanation:
Linnaeus’s work accounted for evolution.
Linnaeus did not use structural comparisons.
Linnaeus primarily used physical characteristics.
The right option is; Linnaeus primarily used physical characteristics
Some of Carl Linnaeus’s classifications of organisms are incorrect because he primarily used physical characteristics.
Carl Linnaeus, known as the father of taxonomy, was a Swedish biologist who classified organisms according to their physical characteristics. Carl Linnaeus proposed that there were three major groups, named kingdoms. These kingdoms were animals, plants, and minerals. He divided each of the kingdoms into five levels which are; class, order, genus, species, and variety. Organisms were arranged in these levels according to their traits, which include physical appearance such as body size, and shape, similarities of body structure, and way of obtaining food.
