[6] [12] In terms of a food web, a cycle or loop is defined as "a directed sequence of one or more links starting from, and ending at, the same species." [ 13 ] : 185 An example of this is the microbial food web in the ocean, where "bacteria are exploited, and controlled, by protozoa, including heterotrophic microflagellates which are in turn ...
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.
Slow living is a lifestyle which encourages a slower approach to aspects of everyday life, [1] involving completing tasks at a leisurely pace. [2] The origins of this lifestyle are linked to the Italian slow food movement, which emphasised traditional food production techniques in response to the emerging popularity of fast food during the ...

At different times during the cycle, water changes between its different states: liquid, vapor and ice.

A biogeochemical cycle, or more generally a cycle of matter, [1] is the movement and transformation of chemical elements and compounds between living organisms, the atmosphere, and the Earth's crust. Major biogeochemical cycles include the carbon cycle, the nitrogen cycle and the water cycle. In each cycle, the chemical element or molecule is ...
Sea urchins move slowly, crawling with their tube feet, and sometimes pushing themselves with their spines. They feed primarily on algae but also eat slow-moving or sessile animals. Their predators include sharks , sea otters , starfish , wolf eels , and triggerfish .
The carbon cycle of a terrestrial ecosystem. [6] Beginning with photosynthesis, water (blue) and carbon dioxide (white) from the air are taken in with solar energy (yellow), and are converted into plant energy (green). [7] 100×10 15 grams of carbon/year fixed by photosynthetic organisms, which is equivalent to 4×10 18 kJ/yr = 4×10 21 J/yr of ...
