Answer: Tomato plant is a multicellular organism.
Explanation: A multicellular is a organism composed by many types of cells or cell lines. A tomato plant is composed not only by million of cells but by many types of them in the different tissues and organs, for example, leaves have epidermic cells that protect them, stomata cells for gas exchange, chlorenchyme cells that have chloroplasts to do photosynthesis, phloem and xylem cells to transport fluids, etc.
Volcanic eruptions spew alot of carbon dioxide and sulphur dioxide into the atmosphere. These gases when mixed with rain and run into oceans increase their pH. Additionally, these gases are greenhouse gases that increases atmospheric temperatures and consequently those of the seas and oceans.
Low pH and high temperatures kill marine life.
