An ectotherm gets its heat from external sources
(Remember "ecto" means outer, "endo" means inner)
The answer is option B "declining number and variety of the species in an area." Biodiversity is a variety of life for example a ecosystem has many species which makes it a biodiversity. Now a loss of a biodiversity would be loosing a huge amount of species in that area or ecosystem which would mean the answer is option B.
Hope this helps.

<span>The answer is that cell will shrink.</span>
<span>If you put an animal cell in a hypertonic solution means that concentration of the solutes is greater outside the cell, in the solution, than in the cell. Consequently,</span> the water concentration of the cell's cytoplasm is higher than that of the hypertonic solution. Since the aim is to balance water concentration on the inside and outside of the cell, the water will exit the cell. The cell will lose water and, consequently, will shrink in size.
