Karen is NOT correct. This is because the sun's energy is a renewable resource. This means that its use is sustainable hence it is a substance of economic value that can be replaced or replenished in the same or less amount of time as it takes to draw the supply down. Though the sun is a finite resource, it cannot be depleted within human timescale.
Plants are producers and make their own food through a process of photosynthesis.
Organisms are classified into domains according to shared characteristics.
"Eukaryote" roughly translates as "truly nucleated" and refers to organisms with a membrane-bound nucleus.
Such membrane-bound organelles are thought to have arisen via the invagination of the cell's own plasma membrane.
Other organelles such as the mitochondria and the chloroplast are believed to have once existed as separate organisms, but which were engulfed by other cells, forming a symbiotic relationship.
