​Energy Pyramids

​An energy pyramid is an illustration of the reduction in energy (10% rule) as you move through each trophic level in an ecosystem.

​

Multiple Choice

,

A. Zoo Plankton: Feeds on phytoplankon. Lives in the water and is often preyed upon by fish and carnivorous plankton.

B. Harbour Seal: Feeds on various fish like arctic cod and capelin. Is preyed upon by harp seals and killer whales.

C. Phytoplankton: Produces it's food through the sun. Often fed upon by zoo plankton, which are herbivores.

D. Arctic Cod: Feeds upon various types of plankton including carnivorous and zoo plankton. Eaten by arctic birds and seals.

What is the correct order, from bottom to top, for the above organisms in an energy pyramid?

• B-D-C-A

• C-A-D-B

• A-B-C-D

• D-A-B-C

Multiple Choice

In the energy pyramid pictured, the producer starts with 3,000,000 kcals of energy. What would the energy be at the secondary consumer level?

• 300 kcal

• 3000 kcal

• 30,000 kcal

• 300,000 kcal

Multiple Choice

As you move up the pyramid, not all energy is transferred to the next level. What happens to the energy that is not transferred?

• It's lost as heat

• It's given to the consumer in the level below

• It's used as a protein

• It's used as carbohydrates

​Genetic Relatedness

​When predicting genetic relatedness, those populations that live closer to each other tend to be related more genetically similar due to interbreeding.

​

​When two populations are more closely related we would expect to see more similarities in their DNA.

Multiple Choice

A new allele in the elk population gives them darker fur.  What will determine if this adaptation becomes more common?

• It's evidence of interbreeding

• It helps them digest grass better

• It helps them be seen in daylight

• It helps them survive and reproduce

​Cellular Respiration and Photosynthesis

​Cellular respiration is a process that both plants and animals go through.

​Photosynthesis is a process that only plants go through.

Multiple Choice

What is the relationship between cellular respiration and photosynthesis?

• The reactants of one are the products of the other

• Cellular respiration only occurs in animals

• Photosynthesis includes ATP energy

• There is no relationship

Multiple Choice

• There are 9 on each side
