What is an autotroph and what is a heterotroph
Usimov [2.4K]

Autographs are organisms that make their own food/energy. The only example I can think of (and the only one I think exists) is plants. They make glucose from the sun and other stuff

Heterotrophs are organisms that needs to get its energy from other sources. You and me are heterotrophs (well unless you are a plant lol). We have to eat food to get energy to survive.

Hope this helped!!!

Which of these is a piece of evidence supporting the theory of evolution?
ycow [4]

The C option is Correct.

  • All the Galapagos finches exist on the same island.

Galapagos finches is a piece of evidence supporting the theory of evolution.

Darwin's finches comprise a group of 15 species endemic to the Galápagos (14 species) and Cocos (1 species) Islands in the Pacific Ocean. The group is monophyletic and originated from an ancestral species that reached the Galápagos Archipelago from Central or South America.

On his visit to the Galapagos Islands, Charles Darwin discovered several species of finches that varied from island to island, which helped him to develop his theory of natural selection.
