Answer:
According to what is observed in point A of the graph, referring to the population of beetles, there is no competition for resources.
Explanation:
The graph shows that a controlled population of beetles, where other individuals do not enter or leave, experiences <u>progressive growth over time</u>. This is because the population has sufficient resources to guarantee their development, the birth rate exceeds that of mortality and there is no competition for these resources.
The adequate amount of resources allows that, at point A, the carrying capacity has not been reached, a consequence of no competition among members of the same species, which ensures that the net population growth rate is maintained or even increase.

Asteroid impact
Volcanic eruptions
Explanation:
Asteroid impact and volcanic eruptions are two common events that could lead to a mass extinction.
A mass extinction is an abrupt decrease in life on earth due some catastrophic event.
- The collision of a large bolide on the surface of the earth is a catastrophe in itself.
- The collision and its aftermath have destructive consequences on life.
- The force of the collision can reverberate in form of vibration throughout the earth.
- It can cause heating of the earth surface.
- Volcanic eruptions can become global phenomenon that upsets the earth balance.
