ECOLOGY

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

slide3
Biotic factors are all the living things or their materials in the environment. This would include organisms, their presence, parts, interaction, and wastes.
slide4
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

slide8
There are many typesofheterotrophs…FYI… “vore” is a suffix that means “an organism that eats a particular diet”
slide14
Symbiotic relationships involve at least one of the organisms benefitting from the relationship…just like on FB, there are many type of these relationships!
slide20
A niche is the role an organism plays in its environment (where it lives, what it eats, how much space it needs).
slide22
A balanced ecosystem is one in which there is enough food, water, shelter & appropriately arranged space for all organisms in that ecosystem.
feeding relationships
Feeding Relationships

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

slide33
The 10% Rule was 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. 
slide35
Carrying capacityis the maximum number of organisms the resources of an ecosystem can support.  

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

slide36
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".
