The wings in birds and insects are not considered as evidence of relatedness because they differ in structures even though their functions may be the same.

Organs in different organisms that are different in structures but similar in functions are referred to as analogous organs. Even though analogous organs serve as evidence of organic evolution, they are indications that organisms differ in the paths taken to evolve.

Some other organs may be similar in structures but different in functions. These types of organs are known as homologous organs and are indications that organisms are kind of related in the path taken to evolve.

The place where a group of organisms lives is called the habitat. The combination of the community and habitat is called the ecosystem.

An ecosystem is basically the neighborhood where animal lives. The habitat is the animal's address in that neighborhood. Some animals can survive in more than one habitat. Other animals are limited to certain habitats. For example, moose habitat is more specific than gray squirrel habit.

Moreover, ecosystem is defined as the interrelationships between the biotic and abiotic component of the environment. Whereas habitat is defined as the natural environment in which a particular species of plants and animals lives.

Therefore, a habitat is a place where an organism makes its home. A habitat meets all the environmental conditions an organism needs to survive. For an animal, that means everything it needs to find and gather food, select a mate, and successfully reproduce.

For plants, light is an external stimulant. Phototropism is a response to light that plants have. The plant responds by orienting its growth in the direction of the light.

A stimulus is an occasion or any change in the environment that causes an organ or tissue to have a certain functional response.

An external or internal trigger is possible. Sensitive to external stimuli like sound and touch are sense organs like the ear and sensory receptors like those in the skin.

Direct one-to-one stimulus-response reactions are the most basic sort of response. The stimulus is a change in the environment, and the response is how the organism responds to it.

A stimulation that comes from outside the organism is known as an external stimulus. Light is one example of an outside stimulation. Although it comes from outside the body, it has an impact there as well.

Thus, it can be concluded that light is an external stimulus.
