Some ecosystems are marine, others freshwater, and others yet terrestrial—land based. Ocean ecosystems are most common on Earth, as oceans and the living organisms they contain cover 75% of the Earth's surface. Freshwater ecosystems are the rarest, covering only 1.8% of the Earth's surface. Terrestrial, land, ecosystems cover the remainder of Earth.
Human ecology is an interdisciplinary and transdisciplinary study of the relationship between humans and their natural, social, and built environments. The philosophy and study of human ecology has a diffuse history with advancements in ecology, geography, sociology, psychology, anthropology, zoology, epidemiology, public health, and home economics, among others.

Dry wood termites produce small, sand like droppings that they kick out of a hole in the wood the are infesting.
2. Organism/Behavioural Ecology. This is the study of the organism at its fundamental levels and can encompass microbial ecology. In this type of ecology, the main goal is to understand the organism’s behaviours, adaptations for such behaviours, reason for those behaviours as explained through the lens of evolution, and the way all these aspects mesh together.
Video: Community Ecology: Definition & Types Community ecology looks at the interactions between populations of organisms. Here we explore a polar ecosystem in Greenland to describe what community ecology entails and what it really means to be at the top of the food chain.
