Answer:
We can tell that extinctions have occurred in the past by looking at fossils in layers of sediments. If the amount of fossils found match you can infer that they are the same organism and they are extinct. If you can't match up the bones with any animal today.

I'm pretty positive its ecosystem. I hope this helps :)
The structure (shape and number) of an animal’s teeth vary according to what food they consume.
For example, molars- flat teeth at the back of the mouth are very different among different types of animals:
• Herbivores (eat plants) have strong and flat molars ,
• Carnivores (eat meat) have limited number of molars,
• Omnivores (eat combine food) have molars for grinding.
On the other hand canine teeth are small or sometimes don’t even exist in herbivores are very defined and sharp in carnivores.
The <u>trait</u> that helps a living organism to survive in its particular habitat or ecosystem is a feature that is most likely to be passed on to subsequent generations.
<h3>What is natural selection?</h3>
Natural selection can be defined as a biological process in which living organisms (individuals) possess certain inherited traits, qualities, and characteristics that enables them in their particular habitat or ecosystem, to successfully adapt to certain environmental factors, survive, and reproduce, as well as passing these traits and genes to their offspring or subsequent generation.
This ultimately implies that, a <u>trait</u> that helps a living organism to survive in its particular habitat or ecosystem is a feature that is most likely to be passed on from generation to generation.
