Sea otters are part of a giant kelp ecosystem. They feed on sea urchins that feed on kelp. How does hunting sea otters affect the population of sea urchins and kelp in the ecosystem?

1. Protists

2. The presence of cell structures in the cell
3. The presence or absence of seeds
4. Nonvascular plant

4. is wrong it is Protist, everything else is right

Based on the given information, the multicellular organism that is small, green, and has chloroplasts, and all of its cells function in the same way is most likely to be a plant, specifically a moss or a fern. Both moss and fern are multicellular plants that contain chloroplasts and are characterized by their small size. However, moss and fern have distinct characteristics that differentiate them from one another. Moss is a non-vascular plant, while ferns are vascular plants with specialized tissues for conducting water and nutrients.
