KJMS Food Chain and Food Web Vocabulary

What is a complex network of feeding relationships among organisms in an ecosystem?

• Food chain

• Food web

• Nutrient cycle

• Energy pyramid

Energy level in an energy pyramid that contains organisms that share the same sources of energy. (They produce/consume the same type of things.)

• Trophic Level

• Energy Source

• Food Chain

• Ecological Niche

What do you call an animal that eats only animals?

• Herbivore

• Carnivore

• Omnivore

• Detritivore

What is an organism that obtains energy from the foods it consumes?

• Autotroph

• Heterotroph

• Phototroph

• Chemotroph

What is the significance of producers in an ecosystem?

• Producers are always the first organism in a food chain and forms the basis for all food webs and energy pyramids.

• Producers are organisms that consume other organisms for energy.

• Producers are the top predators in an ecosystem.

• Producers are responsible for decomposing organic matter.

Organism that hunts other animals and consumes them for energy.

• Prey

• Herbivore

• Predator

• Scavenger

What is the term for the graphical representation of energy levels in an ecosystem?

• Energy pyramid

• Food web

• Trophic level

• Biomass chart

What is the primary source of energy for most ecosystems?

• Sunlight

• Wind

• Geothermal heat

• Nuclear energy

Animals use 90% of the energy they consume for their own life processes or heat and 10% of the energy is available to be transferred to the next trophic level in an energy pyramid.

What is this concept known as?

• 10% Rule

• Energy Transfer Principle

• Trophic Level Theory

• Metabolic Energy Law

What is the term for organisms that produce their own food using sunlight?

• Heterotroph

• Autotroph
