What can you infer about an ecosystem that depends on chemoautotrophs for food?

Answer:

Chemoautotrophs are the organisms which derive energy from oxidation of electron donating elements in their environment i.e. they get their energy from chemical reactions rather than sunlight (organisms which derive their energy from sunlight are called photoautotrophs.)

Chemoautotrophs use elements like hydrogen sulphide, ferrous oxide, elemental sulphur, hydrogen and ammonia as their electron donating elements.

They usually synthesize required organic compounds from carbon dioxide.

Mostly, they are archaea or bacteria, extremophiles and are found in extreme conditions such as deep sea vents, extreme saline areas, areas of high temperature(such as lava beds), areas of low pH etc. In addition, they are the primary producers of such ecosystems.

Different types of chemoautotrophs are thermophiles, halophiles, methanogens, sulphur oxidizers, thermoacidophiles etc.

Chemoautotrophs made their food by themselves using the energy from the sun. This means that an ecosystem that depends on chemoautotrophs for food is DEPENDENT ON SUNLIGHT FOR FOOD AND SURVIVAL. This is because the chemoautotrophic organisms are the primary producers in that ecosystem.

What animals did the grant study in galapagos island?

Galapagos finches did the grant study in Galapagos 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.

What did he observe?

During the survey voyage of HMS Beagle, Darwin was unaware of the significance of the birds of the Galapagos. He had learned how to preserve bird specimen while at the University of Edinbugh and and had been keen on shooting, but he had no expert in ornithology and by this stage of the voyage concentrated mainly on geology. Nonetheless, these birds were to play an important part in the inception of Darwin’s theory of evolution by natural selection.

What was the brief goal of their studies?

All of Darwin's observations and insights, plus reading of increasing population growth and demand for limited resources, brought him to his theory of natural selection. Briefly, this means that individuals better adapted to their environment survive and increase in number through reproduction.

What did they conclude?

Conclusion:

Charles Darwin deserves primary credit for the theory of evolution. He developed existing ideas about descent with modification while providing a large body of evidence in support of them, and he was the first person to perceive thatnatural selection is the primary force behind evolution.
