Ecology

An organism that produces its own food supply from inorganic compounds is called a(an)

• heterotroph
• consumer
• detritivore
• autotroph

What is the original source of almost all energy in most ecosystems?

• carbohydrates
• sunlight
• water
• carbon

What is the term for each step in the transfer of energy and matter within a biological community?

• energy path
• food web
• trophic level
• food pyramid

What is the major difference between a community and an ecosystem? 

• A community involves only the biotic, not the abiotic
• An ecosystem only includes herbivores and carnivores-- no decomposers
• An ecosystem involves only the biotic, AND THE abiotic 
• An ecosystem is just a larger community

What are the correct types of Trophic levels? 

• Producers 
  Primary 
  Secondary 
• Primary
  Secondary
• Producers 
  Consumers 
  Decomposers
• Producers 
  Primary 
  Secondary 
  Tertiary 

What are the major differences between a species and a population? 

• Populations consist of ALL of the individual organisms within a species in a given area/ecosystem that are fertile
• Populations are a collection of many different types of species that are not related to each other
• Populations are just a larger amount of individuals
• Populations are the number of individuals within a species that are identical 

What makes Fungi so unique when it comes to trophic levels?  

• They are producers so they can be high or low 
• They are consumers of only plants
• They are consumers of all types of organisms because they decompose 
• They are consumers of only the primary trophic level

What are the plants in this picture? 

• Heterotrophs 
• Autotrophs
• Carnivores 
• Herbivores 

Different populations living and interacting with each other in the same area

• Biome
• Ecosystem
• Community
• Niche

The non-living part of an ecosystem

• Ocean
• Lava Flow
• Birds
• Abiotic
