<span>Carbon dioxide is a colorless and odorless gas that is vital to life on Earth. This naturally occurring chemical compound is made up of a carbon atom covalently double bonded to two oxygen atoms. Carbon dioxide exists in Earth's atmosphere as a trace gas at a concentration of about 0.04 percent by volume. Natural sources include volcanoes, hot springs and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, in ice caps and glaciers and also in seawater. It is present in deposits of petroleum and natural gas.</span>

Answer:
The answer is - Biomass decreases as energy is transferred from one level to another.
Explanation:
The options are;
A. Chipmunks and insects can occupy the same niche.
B. As the number of bears in this community increases, the number of chipmunks will increase.
C. Insects are classified as omnivores in alpine meadow communities.
D. Biomass decreases as energy is transferred from one level to another
The answer is D. Biomass decreases as energy is transferred from one level to another
The energy pyramid being referred to is in the attachment below.
Biomass is an organic renewable source of energy derived from plants and animals. As animals at the lower trophic levels are consumed by animals at the higher trophic levels there is transfer of energy, however it is not all the energy that are transferred equally. As a result, at each trophic level there is decreased energy and biomass that is transferred from one level to the other.
Answer:
The correct answer is - microevolution.
Explanation:
Microevolution is the very small evolutionary change specially allele frequencies on the level of species that occurs slowly over period of time. These changes occurs on the level of DNA or genetic level.
These evolution can be caused by the natural selection process or genetic drift over the generation of the species or population over period of the time. It is the study of the evolution that occurred on level of separated gene pool.
Thus, the correct answer is- microevolution.
<span>ENZYMES ARE PROTEINS. All proteins are made up of amino acid.. Enzymes are used as catalysts in metabolic reactions in living organisms. They help to speed up the rate of chemical reaction but they are not used up in the reaction. Enzymes requires optimum conditions to function optimally. </span>
