The part of the river that would have animals with very muscular bodies and adaptations that survive in turbulent water is the transition zone.
Green plants need water (H2O) and carbon dioxide (CO2) for the process of photosynthesis.
Although CO2 has carbon, it's inorganic (there are some chemistry rules for what compounds are organic/inorganic, but I won't talk about them here).
Answer:
Ancient landmasses
Explanation:
The same fossils being found in widely separate areas can help scientists infer the geography of the continents of that time.
For example: Africa and South America used to be connected during the Permian Period.
Scientists can confirm this because both continents are home to similar fossils.
