Natural selection is the process that result in the adaptation of an organism to environment by means of selectively reproducing changes in its genotype, or genetic constitution. It is the a key mechanism of evolution. Charles Darwin popularised the term "natural selection" contrasting it with artificial selection, which is intentional, whereas natural selection is not.
To make it simple, let's have a group of beetle composing of green and some are brown as an example. here, there is a variation in traits. Since the environment could not support continuous population growth, not all species can reproduce to their full potential. Green beetles can easily be eaten by other species like birds compared to brown beetles. The surviving brown beetles will then generate brown offsprings because their trait has a genetic basis. Since more brown beetles survive and becomes more common in the population, the process continues until all individuals will eventually be brown. so basically, if you have variation, differential reproduction, and heredity, you will have evolution by natural selection as an outcome.
Answer: the beaks of the finches are adapted to the way the bird usually gets food. :) good luck!
A species is a group of organisms capable of mating and producing offspring. This is another way of saying that a species is reproductively isolated.
It is the order of classification which consists of
Kingdom-Phylum-class-order-family-genus-species.
Please mark me as brainliest.
The correct order would be:
1. A tree absorbs the carbon from the atmosphere into its leaves for photosynthesis;
2. A caterpillar gets the carbon by eating the tree's leaves.
3. A bird gets the carbon by eating the caterpillar.
4. The bird flies into a building and dies instantly. It falls to the ground.
5. The bird decomposes and the carbon returns to the atmosphere.
The carbon cycle is very similar to the water cycle, though it has its own unique ways. Once the carbon is released into the atmosphere, it will either be absorbed by the vegetation, or go up into the higher parts of the atmosphere. If it is absorbed by the vegetation, the organisms that eat the vegetation will get it in them. When the predators eat those organism they get the carbon into their organisms. When the predators die, they start to decompose. When they decompose, the carbon is released from them and it returns to the atmosphere, and the whole process goes all over again.
