ECOLOGY

The study of the interaction between organisms AND between organisms and their physical environment


Biotic factors are all the living things or their materials in the environment. This would include organisms, their presence, parts, interaction, and wastes.


Abiotic factors are those non-living physical and chemical factors in the environment

EXAMPLES

  • light intensity

  • temperature

  • soil and rocks

  • pH level (acid or base)dissolved gases, water, pollutants


Autotroph
Autotroph

“auto”=“self “ “troph”= “feed”

autotroph = producer


Heterotroph
Heterotroph

“hetero”=“different”

“troph”= “feed”

Heterotrophs have to feed upon another organism for food.

Heterotrophs=Consumers


There are many typesofheterotrophs…FYI… “vore” is a suffix that means “an organism that eats a particular diet”



Carnivore meat eater carne in spanish means meat
Carnivore= meat eatercarne in Spanish means meat





Symbiotic relationships involve at least one of the organisms benefitting from the relationship…just like on FB, there are many type of these relationships!





Habitat home
Habitat=Home or harmed.


A or harmed.niche is the role an organism plays in its environment (where it lives, what it eats, how much space it needs).


A or harmed.balanced ecosystem is one in which there is enough food, water, shelter & appropriately arranged space for all organisms in that ecosystem.


Food chain
Food Chain or harmed.



Trophic levels are feeding levels
Trophic bottom and the top predator on top levels are feeding levels


Food webs are combinations of all of the food chains in an ecosystem
Food webs bottom and the top predator on topare combinations of all of the food chains in an ecosystem.


Feeding relationships
Feeding Relationships bottom and the top predator on top

Predatorsis are carnivores that kill their food.   The organism the predator eats is called its prey.  .


The 10% Rule bottom and the top predator on topwas developed by a UF professor, Dr. Odom, who said that only 10 percent of the energy in each transfer is actually captured.  So, plants only capture about 10 percent of the solar energy available to them.   Herbivores capture only 10 percent of the energy stored in plants.  And, the same is true "on down the line" of the food chain. 


Carrying capacity bottom and the top predator on topis the maximum number of organisms the resources of an ecosystem can support.  

Psstt…Hey, Buddy! How many bears can live in this forest???


The most common elements are carbon, hydrogen, oxygen, phosphorus, potassium, nitrogen, sulfur, calcium, iron, and magnesium.  A jingle to help remember these nine elements is "CHOPKNS CaFe Mg" or "see Hopkins Cafe, might good". 


Remember, don’t drain the pond or the fish get ticked!!! phosphorus, potassium, nitrogen, sulfur, calcium, iron, and magnesium.  A jingle to help remember these nine elements is "
