Answer: The population ecologist is trying to determine the density of the oak trees in a forest. It is a part of the job of a ecologist. By detecting the density of the oak trees, an ecologist can easily determine whether the density of the oak trees are decreasing or increasing with time and what are the steps that need to be taken to keep the balance.

D. methods of movement

Answers

Answer: The correct answer for the blank is A.biochemical diversity.

Bacteria can thrive in various environmental conditions such as hot springs, salt flat, polar ice caps because of their biochemical diversity.

For instance, the organisms belonging to the domain archaea ( such as methanogens) live in extremely harsh environmental conditions. They have ether linked lipids in their cell membrane ( unlike bacteria, which possess ester linked lipids) and do not have peptidoglycan in their cell membrane. This provides them an advantage to survive under harsh conditions.

i think its A because the small size , shape and the methods of movement have nothing to do with the environments it can survive in
