Define Ecology.

Study of how living things interact with each other and with their environment.

What is a trophic level? 

The step or position in a food chain or food web that shows how energy and nutrients flow through an ecosystem

100
True or False: A food chain should be drawn in a circle to accurately represent energy flow through an ecosystem. 

False

100

When water falls from the sky its called what? 

Precipitation 

100

What is Mr. Hackett's favorite pass time? 

Fishing

200

What is a niche? 

 The role an organism occupies in an environment. 

200

True or False: Energy gets recycled after it reaches the top level predators / decomposers. 

False
200
What direction do we draw the arrows in a food chain or web? Why? 

We draw them as energy moves through the ecosystem. Pointed towards the organism that consumes the other until we reach the top level predator or decomposers. 

200

What is the difference between climate and weather? 

Weather is a short term measure of abiotic factors such as wind, precipitation, temperature. Climate is long term trends in a specific geographic location.

When was Mr. Hackett's anniversary? 
May 29th. 
300

Which of the following describes a population?

All the organisms of one species in one area  

300

How much energy gets transferred as it flows to the next succeeding level? 

10%

300

What is an Autotroph?

An organism that produces its own food through photosynthesis 
300

What biome do we live in? 

Temperate Deciduous Forest

300

What is the name of the original crayfish in Mr. Hackett's tank?

Kevin

400

Name 3 abiotic factors in an ecosystem.

Sunlight, water, pH, soil, minerals, air / composition

400

You have 4,000 KJ of energy at your 1st trophic level. How much would you have at your 3rd? 

40 KJ

400

Tapeworms get food by eating the host's (animal) partly digested food, depriving the host (animal) of nutrients. Which type of symbiotic relationship is this?

Parasitism 

400
List 3 examples of how CO2 gets into the atmosphere.
Combustion, Respiration, Decomposition
400

What two other classes does Mr. Hackett teach? 

Geology and Astronomy

500

This is the maximum number of individuals an environment can support without degrading resources.

Carrying Capacity

500
Why do we use a pyramid to represent how energy flows through an ecosystem? 

It shows how energy decreases at each trophic level as you move up the food chain.

500

How many organisms are represented in a food chain? Why? 

4 maybe 5. Because we only get 10% of energy to transfer through each trophic level. If we had more levels there wouldn't be enough useful energy.

500

Put the steps of the nitrogen cycle in order (starting with Nitrogen in the air) *order from top to bottom 

Assimilation OR Denitrification 

Nitrification 

Nitrogen fixation

Nitrogen Fixation -> Nitrification -> Assimilation or Denitrification
