How do humans interact with the coral reefs?
How do coral reefs affect humans?
Can you think of any human relationships with coral reefs?
The correct answers are:
1. Lizards;
The animals started to develop traits that would protect them from the natural elements after the lizards. Because of the changes in climate, as well as changes in the functioning of the organism and developing from cold blooded to warm blooded, the animals started to develop feathers and hairs (later becoming a full body fur).
2. Jelly fish;
The Jelly fish is an organism that is very primitive. It has remained largely unchanged throughout the geological time and it seems like it hadn't any real reason to evolve further. It is also one of the oldest species that are still in existence, but also a species that is older even than the hagfish.
Autotrophs are able to live without heterotrophs.
Answer: best adapted to the environment
Explanation: fitness can be thought of as fit for purpose. The most fit for purpose organism is the one best adapted to its environment.
Nevertheless, all the options are characteristic of adaptation
It is not particularly useful to discuss natural selection in terms of individuals and not populations. An advantageous mutation in one individual is the theoretical starting point for a better adapted population, but adaptation happens in a population very slowly if at all if it depends on a single individual. The smaller the population, the higher the probability that the adaptation will be eliminated by chance.
