Answer:
<h2>Sedimentary</h2>
Step-by-step explanation:
Sedimentary rocks are formed when layers upon layers of old sediments from river beds build up. They eventually form a rock. This rock is typically the softest of all the rock types, and therefore the best rock to hold fossils. Igneous rocks are rocks that are formed as a result of volcanic activity. They are created when lava cools. These rocks are unlikely to hold fossils because they are too hard. Metamorphic rocks are rocks that started out life as a different type of rock. They were then subducted under the earths surface where extreme heat and pressure actually changed hem into a different type of rock. Fossils are unlikely in this type of rock because all that heat and pressure has made the rock very hard. Because of this, the most accurate answer would be: sedimentary rock.

The tolerance range is the limit of the abiotic factors in which an organism can survive. It has maximum and minimum limits. The tolerance range of different animal varies.
<h3>What is the Tolerance range?</h3>
The tolerance range is the availability of the abiotic factors in the ecosystem of the species that is maintained and used by the species for survival and functional activities.
It is different for the various organisms as it is affected by the availability and ecosystem of the species. Some of the common abiotic factors are climate, water, temperature, trees etc. Too many and too less factors affect the organism.
Therefore, option a. tolerance range varies for the organisms.

Because water takes longer to cool off and to heat up then land so areas near large masses of water are kept at a higher or lower temperature because the water "loans" its temperature to the land. <span />
