Answer:
c. a natural disaster
Explanation:
A limiting factor in an ecosystem can either be density dependent or density independent. A density independent limiting factor is that which does not rely on the density of a population to affect it's size.
A density independent factor affects the population size irrespective of how densely populated the population is. Examples of density independent limiting factors that can affect a population are natural disasters like fire outbreak, hurricane, earthquake etc.
Hi!
The correct order would be:
Neutron Stars (Smallest)
White Dwarf
Giant Stars
Supergiant Stars (Largest)
Neutron stars are generally smaller stars that have a radius that is generally about 10 kilometers in radius, and highly dense.
White Dwarf stars have a size of about the sun, with a radius that is generally about 7000 kilometers which is nearly the same as that of the Earth.
Giant stars are considerably larger stars with a radius that falls in a range of 10- 100 solar radii.
Supergiant stars are the largest of this selection, with radius that may lie in a range of 30 - 1000 solar radii.
Hope this helps!
Answer:
Stars do not emit sufficient light to help locate them accurately in the night sky. The revolution of Earth makes the sun and the planets move on the ecliptic with respect to the stars.
Explanation:
Rotation and revolution causes changes in star charts. When the Earth rotates, move a way from the sun and when you have rotated far enough it will be nights and you will observe stars but as the seasons changes you will see different stars because u will change to different position. The revolution of the Earth make the stars and sun move ecliptic.

Answer : Radiational Cooling
Explanation: Continental polar (cP) or continental arctic (cA) air masses are cold, dry, and stable. These air masses originate over northern Canada and Alaska. They move southward, east of Rockies into the Plains, then eastward.
