Answer:
C: a coastal region with three ecosystems, each of which supports many different species
Explanation:
Biodiversity means the variety of life in the world or in a particular habitat or ecosystem. So, a costal region with three ecosystem and each has many species would be a biodiversity.
In exothermic reactions, the products have higher energy than the reactants, and in endothermic reactions, the reactants have higher energy than the products.
That would be the synthesis of body mass in a primary consumer (herbivore who eats the plant).
False. Strontium 90 has a half life of only 30 years, and as millions of years pass, about the time fossils have been around, most if not all of any strontium would have decayed.
