Energy Flow in Ecosystems

Animal that gets its energy and nutrition from eating plants.

• Parasite

• Herbivore

• Carnivore

• Ominvore

Organisms that produce their own food mostly through photosynthesis (producers). Examples are plants and algae.

• Ominvore

• Detritivore

• Heterotroph

• Autotroph

Organisms that get their energy and nutrition from other organisms (consumers).

• Heterotroph

• Autotroph

• Decomposer

• Detritivore

Heterotrophs that get energy and nutrition from dead or decaying organisms or their waste products and recycle nutrients back to the ecosystem.

• Producer

• Trophic

• Decomposer

• Autotrooph

The level in an Ecological pyramid that includes all the organisms that share the same place in a food chain.

• Trophic Levels

• Toxic Levels

• KeKe Levels

• Environmental Systems

Autotrophs--The bottom trophic level where all organisms produce their own food, usually by photosynthesis.

• Trophic Levels

• Producers

• Ominvores

• Herbivores

Herbivores--The second trophic level where herbivores eat the primary producers.

• Detritivores

• Autotrophs

• Producers

• Primary Consumers

Only 10% of the energy is passed on from one trophic level to the next. 90% is lost as heat due to cellular respiration or waste.

• Tertiary Consumer

• Biotic Factor

• Abiotic Factor

• 10% Rule

Complex trophic relationships in an ecological pyramid.

• Food Chain

• Food Web

• Abiotic Factor

• Biome

Parts of an ecosystem that are living or deal with the living. Examples include producers, consumers, decomposers, predation, disease, competition, parasitism, and symbiosis.

• Abiotic Factors

• Biotic Factors

• Community

• Population
