Answer:
Basically, the ecosystem consists of all plants and animals, that interact with each other, and are living in a particular territory. Plants and animals represent the biotic (living) component of the ecosystem, while the soil, minerals, gasses, climate etc. represent abiotic (non- living) part.
Carbon is an essential element for all living beings and it is the main component of both organic and inorganic components.
Now, the question is how does that carbon enter the biotic part of ecosystem from the atmosphere (abiotic part).
In the atmosphere, carbon is mostly found in the form of carbon dioxide (CO₂). Plants are able to use it in this form, and with water and sunlight, through the process of photosynthesis, incorporate it in the organic components, such as sugar and complex carbohydrates. Animals that feed on plants can now ingest these compounds, making it part of their own organisms.
In this way, photosynthesis is the main process by which carbon from the atmosphere enter the biotic part of the ecosystem.
Answer:
The answer is D. help protect cells from viral infection.
Explanation:
Interferons are proteins or glycoproteins that different cell types produce in response to various stimuli among which viral infections stand out.
Type I interferons are synthesized in the initial stages of infection or even before other immune responses are activated. they possess the antiviral, anti-proliferative and immunomodulatory properties and their synthesis is induced in response to the presence of single or double stranded viral RNA, to avoid their replication.
naturally occurring.

True
The The National Wildlife Refuge were started in 1903 when there was need to save brown pelicans. This refuge provides home to more than 700 varieties of birds, more than 1000 species of fish, 250 kinds of reptiles and amphibians.
