Yes.
Diatom via a covalent bond
Rainwater.
No. Rainwater is usually slightly acidic because of the carbon dioxide dissolved in it. Sometimes, it can be strongly acidic, if pollutants like sulphur dioxide and nitrogen dioxide are dissolved in it. Both weakly and strongly acidic rainwater react with some rocks, but only ones that are alkaline. Chalk is almost pure calcium carbonate and reacts fairly quickly with rainwater. Other rocks that contain calcium carbonate include limestone and marble and these react a little more slowly. But some rocks, like sandstone, are actually acidic and don't react with rainwater (though they are still physically weathered by rain). Granite also doesn't react with rainwater and it physically weathers much more slowly.
diatom is a producer
Diatom use photosynthesis to get energy.
Diatom Enterprises was created in 2004.

Carbon dioxide (CO2) is the most common form of carbon that dissolves in rainwater. When CO2 from the atmosphere combines with rainwater, it forms carbonic acid (H2CO3), which is responsible for the mildly acidic nature of rain. This dissolved carbon in rainwater can then be utilized by plants for photosynthesis or can react with minerals in soil and water bodies.
no
Rainwater is slightly acidic due to the presence of carbon dioxide, which can react with the calcium carbonate in limestone to dissolve and weaken the stone over time. This process, known as carbonation, causes erosion and weathering of limestone buildings, leading to their deterioration.
Diatom exoskeletons, or frustules, are made from silica. To get a clearer insight into this material Go to the related link (AFM maps the diatom exoskeleton) below.
Lactobacillus is a bacterium, not a diatom or euglena. It is a type of lactic acid bacteria that is commonly found in the digestive system and is also used in the fermentation of foods such as yogurt.
