It is thought that dust particles in the atmosphere resulted in cooling during the early Paleocene.
The cytoskeleton of a cell forms its shape.
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.
