Ecology

By: Carrington Campbell

Ecology is the branch of biology that deals with the relations of organisms to one another and to their physical surroundings.

Amur Tigers

Amur tigers, also known as Siberian tigers, are located in northeast China, eastern Russia and parts of North Korea. This region is called the Amur Region, named after the Amur River which forms a small portion of the eastern border between China and Russia. This region is characterized by mountainous areas and coniferous forests. The climate of the Amur region largely varies from summer to winter. In the summer, it may be mild to hot. In the winter, it may be bitterly cold, especially at higher altitudes.

Individual-a single Tiger  
Population-a group of the same species.

Amur Tigers live alone and aggressively scent-mark large territories to keep their enemies away. They are powerful hunters that travel many miles to find prey, such as elk and wild boar, on nocturnal hunts. Tigers use their distinctive coats as camouflage (no two have exactly the same stripes) and hunt by stealth. They lie in wait and creep close enough to attack their victims with a quick spring and a fatal pounce. A hungry tiger can eat as much as 60 pounds in one night, though they usually eat less.

Ecology examines patterns such as variation in species richness, equability,productivity and food web structure it also examines processes such as predator-prey population dynamics, succession, and community assembly.

Community-A group of different organism in the same area.

Ecosystem-community of interacting organisms and their environment.

They need biotic factors like food to survive and they need abiotic factor for shelter etc.

Protista

Paramecium-A single celled freshwater animal that has a characteristic slipper like shape and is covered with cilia.

Plantae

Sunflower-A tall North American plant of the daisy family, with very large golden-rayed flowers.

Fungi

Mushroom-a fungal growth that typically takes the form of a domed cap on a stalk, often with gills on the underside of the cap.

Animal

Animal-a living organism that feeds on organic matter, typically having specialized sense organs and nervous system and able to respond rapidly to stimuli.

Characteristics of  Kingdoms

Protista-they are unicellular. The can move around by flagella(tail like whip), cilia(hair like projections) and pseudopods


Plantae- made up entirely of plants. While the plants themselves are varied in almost every way, they share common characteristics. Each species in the kingdom Plantae are multicellular.

Fungi-Eukaryotic and it is a decomposer  because it eats off of dead animals until it is able to be eaten completely.


Animal
. Animals are multi-cellular. They are not single-celled organisms. They are also eukaryotes and are not prokaryotes like bacteria and archaea.

Food Web

Food chain

Wolfs role in the ecosystem

Wolves play a vital role in maintaining the health and sustainability of the landscape in the greater Yellowstone region and our western lands. They are a keystone species, one that has a disproportionate impact on its environment relative to its abundance. Since their return in 1995, wolves have benefited this ecosystem by regulating prey numbers and movements—allowing stream bank habitats to recover, reducing densities of coyotes, and providing food for scavengers.

Wolfs are  heterotroph which means that they cannot create their own food.

Definition of Producer,Consumer,and Decomposer

Producer- a producer refers to any organism that absorbs the sun's energy and  turns it into food. Producers are normally green plants such as grass that use the sun's energy for the photosynthesis process to produce/create their own food

Consumer-an organism, usually an animal, that feeds on plants or other animals.

Decomposer-an organism, usually a bacteria or fungus, that breaks down the cells of dead plants and animals into simpler substances.


Sun- is very bright and provides energy for plants.

Rain-drops from clouds when they have too much water in them

Cloud-condensed water vapor floating in the atmosphere, typically high above the ground.

Animals need abiotic factors like grass and fruits to get nourishment to survive they respond by eating them.
