The ocean plays a key role in the water cycle as it is the source of 86% of global evaporation. [2] The water cycle involves the exchange of energy, which leads to temperature changes. When water evaporates, it takes up energy from its surroundings and cools the environment. When it condenses, it releases energy and warms the environment.
View of Amazon basin forest north of Manaus, Brazil. The term “biotic pump” infers a circulation system driven by biological processes. This concept shows forests as being the major factors in manipulating atmospheric processes to cycle rainfall taken up by trees throughout all continents and back to the atmosphere for further cycling.

Chickens are natural foragers, Purina Mills reports. So, there is a variety of vegetables, herbs and perennials that are part of a chicken's diet. So, there is a variety of vegetables, herbs and ...
The densest areas of biodiversity are found in the forest canopy, a more or less continuous cover of foliage formed by adjacent treetops. The canopy, by some estimates, is home to 50 percent of all plant species. Epiphytic plants attach to trunks and branches, and obtain water and minerals from rain and debris that collects on the supporting ...
Amazon River rain forest in Peru. Tropical rainforests are hot and wet. Mean monthly temperatures exceed 18 °C (64 °F) during all months of the year. [4] Average annual rainfall is no less than 1,680 mm (66 in) and can exceed 10 m (390 in) although it typically lies between 1,750 mm (69 in) and 3,000 mm (120 in). [5]
There is a long-standing controversy over the basic need for a chicken coop. One philosophy, known as the "fresh air school", holds that chickens are mostly hardy but can be brought low by confinement, poor air quality and darkness, hence the need for a highly ventilated or open-sided coop with conditions more like the outdoors, even in winter.

Water is the medium of the oceans, the medium which carries all the substances and elements involved in the marine biogeochemical cycles. Water as found in nature almost always includes dissolved substances, so water has been described as the "universal solvent" for its ability to dissolve so many substances.
RSPCA standards state that in order for chickens to be free range, there must not be more than 13 chickens per square meter. [23] Free-range broiler systems use slower-growing breeds of chicken to improve welfare, meaning they reach slaughter weight at 16 weeks of age rather than 5–6 weeks of age in standard rearing systems.
