Answer:

Explanation:

The fossil record shows that different species have evolved over time. The fossil record also provides evidence of how a specific organism evolved from earlier species. The fossil record shows that organisms have become more complex over time. It also shows which organisms lived during the same time period, which have a common ancestor, and which have become extinct.

<h2><u>Answer:</u></h2>

Fossil: is preserved pre historic life form present under ground at high pressure for a long time.Animal die and burried under layers of sediments.

It provides evidence about the history of life on earth. It also shows  different groups of organisms, including species,that have changed over time. Because the formation of any fossil depends upon the precise combination of conditions.

As the world changes, plants and animals change with time . From fossils we compare organisms of modern time with ancient , the species we see today are very different from species that lived in the past. Thus, the fossil record can be used to show that organisms changed to meet new condition.

Answer: The correct answer is-

C.They replaced carbon dioxide with oxygen in the atmosphere.

Cyanobacteria ( also known as blue green algae) is a large phylum of bacteria that is capable of synthesizing its own food using carbon dioxide and water in the presence of sunlight ( photosynthesis).

They contain a green pigment called chlorophyll that absorbs energy from sunlight and helps in the formation of food ( glucose). They release oxygen as a byproduct in the atmosphere.

As these organisms utilize carbon dioxide ( that is present in the atmosphere) to give oxygen in return, therefore, they affected early atmosphere of Earth by replacing carbon dioxide with oxygen.

Thus, option C) is the right answer.

nikdorinn [45]

The idea was that fertilizing the ocean and seas would lead to the in increase growth of phytoplankton population.


The oceanic plants do not release carbon dioxide into the air when they die because the sinks into the sea carrying with them the carbon dioxide for several centuries. This would then decrease the levels of carbon dioxide from the air as plants absorb carbon dioxide from the air during the process of photosynthesis.
