“Pockets” or small areas where the climate is different from the climate of the region. Examples of this could include the climate created by a city, the climate created by the shade of a forest or even smaller, the inside of a hollow tree, the cleft of a rock, or the inside of an organism for parasite or symbiotic organism…(lichen)
Specialized organisms that recycle nutrients in ecosystems. They secrete enzymes that digest or biodegrade living or dead organisms into simpler nonorganic compounds (N, C, O, P) that producers can take up from the soil and water and use as nutrients.
Examples are bacteria, fungi, and other consumers called detritivores. Detritus is dead organic matter.
Two species or a network of species interact in way that benefits both. Such benefits include having pollen and seeds dispersed for reproduction, being supplied with food, or receiving protection. This is a type of symbiosis.
Examples: clownfish and anenome, birds on rhino, fungi and plant roots form mycorrihzae, protists in termites that allows them to break down cellulose, bacteria in your gut!
The maximum population of a given species that a particular habitat can sustain indefinitely without degrading the habitat. The growth rate of a population decreases as its size nears this maximum population, referred to as K. This is illustrated in an S-curve or sigmoidal shaped logistic growth curve.
Removes suspended solids and some organic wastes (like fats, oil or grease)
Some sources say this is the physical treatment (screens) but other sources say treatment must be chemical, so primary treatment also includes adding flocculants or chemicals that will cause suspended solids to polymerize or “coagulate” so then can be removed
Process includes screens, settling tank where heavier suspended solids settle to bottom and lighter ones float on top.
US federal law requires primary and secondary treatment for all municipal sewage treatment plants.
Advanced or tertiary sewage treatment involves both chemical and physical processes to remove specific chemicals left after primary and secondary treatment…this may include nitrates and phosphates as well as pharmaceutical drugs.
