ecology

• What is a food chain?

  A diagram showing what organisms eat what organisms and the transfers of energy.
• What is the role of a producer in a food chain?

  It is the start of the food chain and is typically a plant that performs photosynthesis.
• What is a primary consumer?

  An organism that eats producers and is at the 1st trophic level.
• What is a secondary consumer?

  A predator that eats primary consumers and is at the 2nd trophic level.
• What is an ecosystem?

  All organisms and non-living organisms in a community.
• What does interdependence refer to in ecology?

  How organisms depend on each other to survive.
• What is biomass?

  The dry mass of energy transferred through organisms in a food chain.
• What does a pyramid of biomass represent?

  A diagram that always takes the shape of a pyramid, showing the biomass at each trophic level.
• What type of consumer is a primary consumer?

  A herbivore.
• What type of consumer is a secondary consumer?
