Answer:
tropical, temperate, and polar
Answer:
The appearance of free oxygen in the Earth's atmosphere led to the Great Oxidation Event. This was triggered by cyanobacteria producing oxygen which developed into multicellular forms as early as 2.3 billion years ago
Explanation:
To clarify what I said here are some questions to help!
How did oxygen first appear?
Whiffs in the air is how oxygen first appeared billions of years ago.
For the most part, scientists agree that oxygen, though lacking in the atmosphere, was likely brewing in the oceans as a byproduct of cyanobacterial photosynthesis as early as 3 billion years ago
When was oxygen found?
2.33 billion years ago
Since its first appearance 2.33 billion years ago, oxygen accumulated in high enough concentrations to have a weathering effect on rocks just 10 million years later.
I don't know if this helped you but if it does, please let me know!
<u>Answer</u>: predator and prey
<u>Explanation</u>:
The described graph illustrates the cycle of a predator and prey population. The population curves for predator and prey are not synchronized with each other and their amplitudes differ.
Changes in the prey population will not result in immediate or exactly identical changes in the predator population.
In the attached image, the red line represents the prey population and the blue the predator population. As it can be observed, when the prey population increases in size, the predator population size increases too.
However, this increase is not of the same size and is delayed in time. The predator population will continue to increase even though the prey population has started to decrease.
This has to do with the fact that the adult predators mated and gave birth when the food availability was still high. However, these new young individuals will not survive and reproduce due to decreasing prey. As the prey continues to decrease, more and more predators will perish.
The same cycle will then repeat over and over again.
Yes Limestone is a sedimentary rock. :)
