Ecology Part 1

Fish, their predators and the water, sunlight, and plants that they rely on would be considered a(n):

• population
• abiotic factor
• community
• ecosystem

A food web is shown below. In this food web, the trophic level with the LEAST energy includes which of the following organisms?

• grasses
• mice
• snakes
• hawks

The diagrams below show a marine food web and an incomplete terrestrial food web. The organism in the terrestrial food web that corresponds to the krill in the marine food web is located X. Which of the following organisms is most likely organism X?

• 
• 
• 
• 

Which type of succession is pictured below?

• Primary
• Secondary

Which type of succession is pictured below?

• Primary
• Secondary

Looking at this Energy Pyramid, which trophic level stores the largest amount of energy?

• The first trophic level - the primary producers
• The second trophic level - primary consumers
• The third trophic level - secondary consumers
• the forth trophic level - third level consumers
• the fifth trophic level - apex predators

Put the following terms in order from smallest to largest: population, biome, biosphere, community, ecosystem, organism

• organism -> Biome -> biosphere -> ecosystem -> population -> community

• Ecosystem -> community -> population -> biome -> biosphere -> organism

• Biosphere -> biome -> organism -> ecosystem -> community -> population

• organism -> Population -> community -> ecosystem -> biome -> biosphere

At each trophic level of the food chain, energy is lost as heat. How much energy is PASSED to the next trophic level?

• 100% is passed
• 90% is passed
• 50% is passed
• 10% is passed
• 0% is passed

Look at the energy pyramid below. Which of the following is the correct flow of energy?

• The vegetation gets energy from the squirrels.
• The eagle gets energy from eating plants.
• The squirrels get energy from eating the eagle.
• The eagle gets energy from eating the squirrels.

According to the figure below, the coyotes would be considered

• producers
• tertiary consumers
• secondary consumers
• primary consumers
