An Introduction on Ecology
The environment is made up of two factors
- Biotic Factor- all living organisms in the Earth
- Abiotic Factor- Non-living parts of the environment. Examples are temperature, soil, water, sunlight and more.
Habitat- Where an organism lives.
Ecological Niche
–Is the total of an organism’s use of the biotic and abiotic resources in its environment.
Niche- A role the organisms play in its environment.
Competitive Exclusion Principle
–States that two species competing for the same limiting resources cannot coexist in the same place.

- Predation- Is when the predator kills and eats the prey.
- Herbivory- Species that eats parts of a plant.
- Parasitism- Gain its nourishment from another organism, which is harmed in the process.
- Mutualism- Benefits both species.
- Commensalism- One species is benefiting from the other without harming them.
The Stages of Ecology from Smallest to Largest
- Population: A group of one species in the same area.
- Communities: Several organisms interacting in the same area.
- Ecosystems: All the members of a community plus the abiotic ( physical) factors influencing them.
- Biomes: That share similar climate conditions
- Biosphere: Entire region of the earth where living things may be found.
Two categories the Biomes will fit in are:
Terrestrial biomes occurs on dry land. These can be different in their climate, vegetation, and animal life. the main biomes include Tundra, desert, forest and grasslands.
Aquatic biomes occurs underwater. It can freshwater or saltwater, saltwater you can find the coral reef biome. Freshwater includes areas of land that is covered in water. those places are lakes, rivers, ponds and wetlands, like swamps and marshes.
The different types of Biomes that are in Terrestrial are Tropical Rain forest, Desert, Savannas, Temperate deciduous forest, Temperate grasslands, Taiga, and Tundra. And, the two major water biomes are freshwater and marine, or saltwater biomes.

Food Chain Shows a one way flow of energy in an ecosystem. Parts of the food chain
Food Web Shows all the possible pathways that energy can take in an ecosystem and how organisms are depending on each other in the ecosystem. |
What gets recycled? Minerals, nutrients, carbon dioxide, Carbon, the Sun, light, and water keeps the cycle going. What keeps the energy flow is through an ecosystem in one direction from the sun or inorganic compounds to autotrophs and then to heterotrophs (consumer)
