Answer:
Due to the presence of limited number of species.
Explanation:
Bear island provide a great opportunity to decipher entire food chains because this island has many animals species which interact with each other or depend on one another due to the presence of less animals for feeding purpose. This island is isolated from the rest of the world so it provide a great opportunity to study the entire food chains that are present at that island. There is less number of species so knowing about their feeding choices is easier for the ecologists.
The differences between the geomagnetism and electromagnetism are given below.
<h3><u>Explanation</u>:</h3>
Geomagnetism is defined as the magnetic field that is located all around the earth. Whereas electromagnetism is defined as the magnetic field that is produced due to passing of electricity through a conductor.
The geomagnetism is formed because of the molten elements of iron etc which are present inside Earth's core, and are continuously moving. It mostly resembles the solid block magnet in its field characteristics. But electromagnetism is different. It can be changed according to the current input which isn't possible for Earth’s magnetic field.
Answer:
Homologous
Explanation:
If two or more species share a unique physical feature, such as a complex bone structure or a body plan, they may all have inherited this feature from a common ancestor. Physical features shared due to evolutionary history (a common ancestor) are said to be homologous.
Answer:
An ecologist must consider both of the speciation and extinction of an organism or when analyzing the diversity the life on earth because of the following reasons;
- It is a role of an ecologist
- It is part of their job
- This will tell the existence of the organism
- The organism’s life span on earth
- How it was existed and were extinct
Explanation:
I’d say it’s the first one and it’s not even the first one probably than the last one
