B) ecosystem, community, population, individual
Explanation:
An ecosystem is the most inclusive level of the ecological system for it comprises of both living and non living organisms that are joined together through the nutrient cycle and the flow of energy. An ecosystem is made up of different communities.
A community comprises of organisms of different species that live and interact with one another in the same habitat.A community is formed by different populations.
A population is made up of many individuals of the same species that can interbreed to give rise to viable offsprings and end up forming a community.

<span>The specimen are placed in vacuum while examining the cells or living organisms. Also, the electron must penetrate inside of the cell and in such conditions, any living organism is not able to survive. Thus, this reason best explains the answer to why dead cells specimen must be used for Transmission electron microscopy.</span>
Answer: Carbonic acid
Explanation: The carbon dioxide when get dissolved in the water is known as carbonic acid. This carbon dioxide from the water is used by the pytoplanktons to perform the process of photosynthesis.
This is a very weak acid which is formed when the carbon dioxide gets dissolved in the water. The carbon dioxide in the environment goes inside the ocean that is used by the organisms and oxygen is released into the environment and inside water.
