If animal cells don’t have chloroplasts, how do they obtain energy?

Plants don't get their sugar from eating food, so they need to make sugar from sunlight. ... Once the sugar is made, it is then broken down by the mitochondria to make energy for the cell. Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria.

They obtain their energy through the proteins the host (animal) consumes.

Hope this helps
