How can you get energy as a living organism?

Organisms, such as humans, take in "substrates" such as glucose, in our food. During a process called respiration, we react these substrates with oxygen to give carbon dioxide and water; this takes place in the mitochondria of our cells.

Explanation:

For plants, they must make their own energy (food) through the process of photosynthesis, using sunlight, water and CO² to produce their food.

Animals and humans however cannot make their own food, and must consume food such as plants or other organisms to get energy.

i got this answer from a really friend, and it was right.

hope this you like it me and a special to that dude!

artists need to create a realistic interpretation so that people in general can relate to the artwork. for a common people, an artist's impression gets increased only if he can create something which would look realistic. an abstract is difficult for a common people to understand whereas if a person can draw a girl with simple pencil sketch and if that looks like a real figure then the latter will be praised more than the former.
