Ecology Sampling Techniques

What is a square called that we use to sample populations?

• grid

• quadrat

• cube

• quarter

What type of population would you ESTIMATE using a quadrat?

• 
• 
• 
• 

Limpets were found in 25 out of 50 quadrats. What percentage of quadrats contained limpets?

• 100%

• 25%

• 50%

• 75%

These four 1m² squared quadrats were place in a 8m² garden. Estimate the total population of flowers in the whole garden.

• 16

• 17

• 8

• 40

• 20

Which organism can be measured with a quadrat?

• lion

• flies

• rat

• dandelion plants

• fish

what is meant by structural adaptations?

• these are ways that organisms behave

• these are things that go on inside an organism's body

• there are no such things as structural adaptations

• these are features of an organism's body structure

These are used to study the distribution of organisms

• microscopes

• transects

• measuring cylinders

• quadrats

Why do scientists use sampling techniques to gather population data rather than counting everything?

• scientists are lazy

• sampling is more efficient and achievable

• sampling is more accurate

• scientists prefer estimations

• sampling is cheaper

Food webs always start with:

• the sun

• producers

• primary consumers

• microorgansims

All the organisms that live and interact in an ecosystem

• Population

• Community

• Habitat

• Interdependent
