❊ Ecology❊ The study of the interaction of populations of living
organisms with other populations and with the environment
❊ Population❊A group of individuals, all of the same species
❊ Community❊A group of different populations
❊ Abiotic factors ❊Oxygen concentration, salinity, temperature,
rainfall, etc.

❊ Mutualism❊A symbiotic relationship between two species
in which both species benefit
EXAMPLE:❊ Microbes in the stomach of cattle
are responsible for the digestion of cellulose (fiber in grass & hay)
❊ The cattle benefit because they use the glucose from the cellulose digestion
❊ The microbes benefit because they get a warm, moist, protected place to live and all they food they need
Symbiotic Relationships

❊ Commensalism❊A symbiotic relationship between two species❊ In which one species benefits, and the other species is
neither helped nor harmed
EXAMPLE:❊ The worms benefit because they get to
travel through nutrient-rich waters as the sea turtle swims around (worms attached to the docks are stuck there)
❊ There is no direct benefit to the turtle having worms stuck on its back, nor does there seem to be any harm done

❊ Parasitism❊A symbiotic relationship between two species❊ In which one species benefits, and the other
species is harmed❊The species that benefits is called a parasite,
and is typically much smaller than the other species (the host)
❊Example: ❊ microorganisms that cause
disease in humans, animals, and plants

❊ Predator-prey❊A symbiotic relationship between two species❊ In which one species captures & kills the other
species for food❊The species are generally about equal in size❊The term is usually applied to animal species (or
certain types of protozoan species)
❊Example: ❊ Lions and
wildebeests, Owl and mouse

A baby hippopotamus that survived the tsunami waves on the Kenyan coast has formed a strong bond with a giant male tortoise.
The hippopotamus, nicknamed Owen and weighing about 300 kilograms (650 pounds), was swept down Sabaki River into the Indian Ocean, then forced back to shore when tsunami waves struck the Kenyan coast on December 26, 2005 before wildlife rangers rescued him.

A-less-than-a-year-old hippo has adopted a male tortoise, about a century old, and the tortoise seems to be very happy with being a 'mother'," ecologist Paula Kahumbu
“It is incredible…
![Page 20: ❊ Ecology ❊ The study of the interaction of populations of living organisms with other populations and with the environment ❊ Population ❊ A group of](https://reader035.vdocuments.us/reader035/viewer/2022062516/56649d785503460f94a5bbb8/html5/thumbnails/20.jpg)
"After it was swept and lost its mother, the hippo was traumatized. It had to look for something to be a surrogate mother. Fortunately, it landed on the tortoise and established a strong bond. They swim, eat and sleep together," the ecologist added.
![Page 21: ❊ Ecology ❊ The study of the interaction of populations of living organisms with other populations and with the environment ❊ Population ❊ A group of](https://reader035.vdocuments.us/reader035/viewer/2022062516/56649d785503460f94a5bbb8/html5/thumbnails/21.jpg)
The hippo follows the tortoise exactly the way it follows its mother. If somebody approaches the tortoise, the hippo becomes aggressive, as if protecting its biological mother," Kahumbu added.

2. Silverfish live and hunt with army ants and share the prey. They neither help or harm the ants.
