3210.2.1—Predict how population changes of organisms at different trophic levels affect an ecosystem.


Producers autotrophs

Producers--Autotrophs

  • Use energy from the environment to make food

  • Main source of energy is sunlight (photosynthesis)

  • Some organisms rely on energy stored in inorganic compounds (chemosynthesis)


Consumers heterotrophs

Consumers—Heterotrophs

  • Rely on other organisms for energy and food supply.

  • Herbivores—eat plants only

  • Carnivores—eat animals only

  • Omnivores—eat plants and animals

  • Detrivores—eat animal and plant remains

  • Decomposers—breaks down organic matter


Food chain

Food Chain

  • A series of steps in which organisms transfer energy by eating and being eaten

  • Arrow points to what is eating

  • GrassAntelopeCoyote


Food web

Food Web

  • Links all the food chains in an ecosystem together


Trophic level

Trophic level

  • Each step in a food chain or food web

  • 1st level is always producers

  • Consumers make up the 2nd, 3rd or higher

Tertiary consumer

Secondary consumer

Primary consumer

Primary producer

  • Biotic and abiotic factors


Assignment

Assignment

  • Create a food web for a particular biome (will be assigned from pgs. 100-104)

  • Most contain at least 5 food chains consisting of a producer, primary consumer and secondary consumer. Each consumer must be labeled as an herbivore, carnivore, omnivore or decomposer

  • At least one predator-prey relationship must be shown

  • At least 2 abiotic factors must be included and labeled
