Endemic species are species that are native to a particular place.

Explanation:

The endemic species are the ones that are highly adapted to a particular niche and prefer not leaving the area they live in. The climate and the setting of a particular region are the most favorable for a particular species. These species thrive nowhere else but in their native region. The availability of endemic food (food that is available only in that region) also makes a reason for the endemic species of birds and animals to not leave their native habitat.

So  if  the sum of the enthalpies of the reactants is greater than the products, the  reaction  will be  exothermic.  if  the products side has a larger enthalpy, the  reaction  is  endothermic. you may wonder why  endothermic reactions, which soak up energy or enthalpy from the environment, even happen

How is this a question? where are the answer choices?
