An autotroph produces its own food while a hetertroph has to find it/hunt for it/gather it
Examples~
Autotroph-Sunflower
Heterotroph-Wolf
The UV rays cause sun spots due to reaction from the radiation.
Biogeographical studies use information for various fields, such as evolutionary biology, geography, geology, and climate science to determine how organisms evolved through time and how the moving of tectonic plates resulting in forming continents, mountain ranges and islands has affected their distribution.
Studies in this field explain how organisms that now live on different continents are very closely related and how the flora and fauna of islands are connected to one of the closest continents etc.
The particles in a hot pan have greater kinetic energy than the particles in a cool oven mitt.
This is because as the temperature of an object increases, the particles gain more energy and therefore move faster, increasing kinetic energy.

The correct answer is:
Plants close their stomata during times of intense heat or drought in order to prevent water loss and maintain homeostasis.
Explanation:
Guard cells tend to open stomata within the day when there are lots of day and close stomata at night when the sun is not present and photosynthesis is not happening. They will also close stomata if the air is dry or hot, which minimizes water waste indoors evaporation.
