Answer:
At the bottom of the sequence
Explanation:
According to the "principle of superposition of strata", the oldest rocks are formed at the bottom of sedimentary rock sequences.
The oldest rock layer would contain the the oldest fossil. Weathering, erosion, transportation and deposition would bring all sediments which includes rock materials and remains of living organisms to the basin where they would be lithified to form sedimentary rocks. This makes the oldest fossil to be at the bottom of the sequence. As time progresses, the fossil sequence would continue to accumulate and young upwards as the strata becomes relatively younger. Also, we know that fossils succeed one another in a definite manner.
This why relative dating of rocks can be possible.

Answer:
Every organisms on the planet requires a specific environmental conditions for its growth and survival. If the environmental condition is favorable, the organisms grow fast and if the conditions are not suitable so it adversely affected the organisms. For example, plants grow best at the temperature between 25 to 40 Celsius. If the temperature goes below 25 or above 40, the growth decrease and sometimes the plant dies. So climate and abiotic factors such as temperature, humidity, light intensity etc has a great impact on the organisms.
