Distribution of phenotypes within a population may be impacted by different types of natural selection. These types of selection include;
Directional selection involves a change in the environment shifts of phenotypes observed. Example is the giraffe neck-length, where the length got longer and longer over time to reach the leaves at the top of trees.
Stabilizing selection , this is a selection where an average phenotype is favored. example is number of eggs laid by birds such that too many eggs will be a waste of energy because some chicks would starve.
Disruptive selection is a selection where individuals with an average value of a trait are affected most while those with values below average are affected least. Example small individuals are capable of hiding from predators while big individuals can not fit in the hiding place but instead will fight with predators.
The reason is two fold, the first is the active volcano of Kilauea implies there is a lot of heat under the big island of Hawaii, and that heat causes the island to be buoyed up. However, the other islands do not have active volcanos, are colder, and have subsided, the 2nd is, because the volcanoes on the older islands are dormant, those islands are and are no longer growing and are steadily eroding away.
Biomes
Explanation:
The most comprehensive ecological unit of the biosphere is the biomes.
Biomes are the largest ecological unit of life.
- They are made up of different population, communities, ecosystems of living organisms and their environment.
- A biome is an ecosystem made up of common characteristics in the environment they are found.
- They have internal regularities in the nature and types of fauna and flora found in such areas.
- Examples of biomes are tundra, rainforest, desert etc
