Answer: Stratigraphy and Biostratigraphy
Relative dating is a method of determination of age, in which one object or organism is compared with the other object or organism found in the heap of strata. It is a method for determining the relative order of the past events, without stating the absolute age.
Stratigraphy is a branch of geology that studies the relative position of the sediments and rocks in the strata with respect to the geological timescale. Biostratigraphy is the branch of stratigraphy which deals with the relative aging of fossils with respect to the strata in which these are found defining a particular period of geological time scale.
Answer:
The 2 ways abiotic factors affect biotic factors are as follows:
- An alligator submerges itself under water to stay cool in the summer.
- A naked mole rat creates burrows underground.
Explanation:
Abiotic Factors:
All non-living factors that is present or influences an ecosystem. Abiotic factors determine the dynamics of an ecosystem such as the terrain, the atmosphere as well as the inhabitant flora and fauna. Water, sunlight, oxygen, temperature, and soil are all abiotic factors.
Biotic Factors:
All living factors in an ecosystem i.e. the plants and animals.
Lets analyze all the options:
- A bird picking food out of an alligator's teeth is an interaction between 2 biotic factors, the bird and the alligator or in another case, the bird and the food.
- Water being oxygenated is an interaction between 2 abiotic factors: water and oxygen.
