Explain how to tell which major groups of living things these come from and how to tell whether they may come from an aquatic habitat or from a terrestrial habitat, if it is possible to tell.

Part B:

Decipher which organism comes from what major groups of organisms and explain how you deciphered this.

1 answer

To decipher which major groups of living things these organisms come from, we can analyze the features provided in the table.

Organism A is the only one with fossils found in stromatolites, indicating that it may come from a photosynthetic organism group such as algae or cyanobacteria. This suggests that Organism A may come from an aquatic habitat. Additionally, Organism A is multicellular, which further supports the idea that it may be a type of algae or other aquatic plant.

Organism B is the only one with fossils with fruiting bodies, suggesting that it may be a fungus. This indicates that Organism B belongs to the fungi kingdom. However, without additional information, it is difficult to determine whether it comes from an aquatic or terrestrial habitat.

Organism C is the only one with teeth, indicating that it may be a vertebrate or some other type of animal. This suggests that Organism C belongs to the animal kingdom. Again, without additional information, it is difficult to determine whether it comes from an aquatic or terrestrial habitat.

Organism D is the only one with fossils with stomates, indicating that it may be a plant. This suggests that Organism D belongs to the plant kingdom. Additionally, Organism D is multicellular, supporting the idea that it is a plant. It is also likely to come from a terrestrial habitat, as plants are primarily found on land.

In summary, Organism A is likely a photosynthetic organism from an aquatic habitat, Organism B is a fungus, Organism C is an animal, and Organism D is a plant from a terrestrial habitat.
