Carbon dioxide enters the plants through its leaves. Present under the surface of leaves are small holes through which carbon dioxide diffuses into the plant to fulfil its requirements. The leaf also gives off oxygen from these same holes in the leaves. These small holes are called stomata which is the plural form. the singular form of this word, or a single hole on the underside of the leaf is called a stoma.</span> After it enters, the plant prepares the other needed requirements to perform photosynthesis such as water, sunlight and other nutrients.

Some bacteria living in the ocean floor can turn methane (a gas) into food.
Nesterboy [21]

Answer:

Option A

Explanation:

Only an autotrophic species can convert methane into food.  

Deep below the sea, methane and hydrogen sulfide are found in abundance. These gases get mixed into the sea water.  

Autotrophic bacteria containing phosynthetic pigments oxidize these dissolved gases thereby producing food.  

Hence these autotrophic bacteria’s will be considered as producers as they produce food.  

Thus, option A is correct.
