Biology is the overall natural science that studies life, with the other life sciences as its sub-disciplines. Some life sciences focus on a specific type of organism. For example, zoology is the study of animals, while botany is the study of plants. Other life sciences focus on aspects common to all or many life forms, such as anatomy and ...
Ecology – study of the interactions of living organisms with one another and with the non-living elements of their environment. Behavioral ecology – the study of the evolutionary basis for animal behavior due to ecological pressure; Ecosystem ecology – study of biotic and abiotic components of ecosystems and their interactions within an ...
Extraterrestrial life – life that may occur outside Earth and which did not originate on Earth. Physical sciences – encompasses the branches of science that study non-living systems, in contrast to the life sciences. However, the term "physical" creates an unintended, somewhat arbitrary distinction, since many branches of physical science ...
The Nara Canal also provides vital water for species living in its proximity and also to its lakes.

Natural sciences: the study of natural phenomena (including cosmological, geological, physical, chemical, and biological factors of the universe). Natural science can be divided into two main branches: physical science and life science (or biology). Social sciences: the study of human behavior in its social and cultural aspects. [1]
In science, the term natural science refers to a rational approach to the study of the universe, which is understood as obeying rules or laws of natural origin.. The term 'natural science' is also used to distinguish those fields that use the scientific method to study nature from the social sciences, which use the scientific method to study human behavior and society; and from the formal ...
The following outline is provided as an overview of and topical guide to natural science: Natural science – a major branch of science that tries to explain, and predict, nature's phenomena based on empirical evidence. In natural science, hypothesis must be verified scientifically to be regarded as scientific theory. Validity, accuracy, and ...
