Phytoplankton because they are producer(producer make their own food).
Put simply, water evaporates from the land and sea, which eventually returns to Earth as rain and snow. Climate change intensifies this cycle because as air temperatures increase, more water evaporates into the air. Warmer air can hold more water vapor, which can lead to more intense rainstorms, causing major problems like extreme flooding in coastal communities around the world.

Plant cells are eukaryotic while bacteria cells are prokaryotic. One characteristic difference between eukaryotes and prokaryotes is that eukaryotes have membrane-bound organelles, such as a nuclei, Golgi apparati, endoplasmic reticula, mitochondria, and so forth. Thus, choice c would be correct here (endoplasmic reticula can be rough or smooth depending on their specific functions).
They left so it would be emigration. Hope that helps!
Two is is the answer, it is incorrect, so in this case it is not scientifically correct because it more of a opinion, not a thing you based on and provide proof for from a scientific experiment.
