Ecology Test: Biology: Unit 7

Front 1

What is the ultimate source of energy?

Back 1

Sunlight

Front 2

What types of organisms can be found at each trophic level?

Back 2

1st: producers

2nd: primary consumers

3rd: secondary consumers (omnivores)

4th: tertiary consumers (carnivores)

Front 3

What do the arrows represent in a food chain or web?

Back 3

He flow of energy and who eats who.

Front 4

How does energy flow through a system?

Back 4

10% rule

Front 5

What are the levels of organization from lease encompassing to most?

Back 5

Species ---> population ---> community ---> ecosystem ---> biome ---> biosphere

Front 6

Why can't there be more than 4 or 5 levels in any single food chain?

Back 6

Once you get to a higher level there's not enough energy

Front 7

10% rule?

Back 7

Roughly 10% of energy is transferred from level to the next. 90% as lost as heat into the environment

Front 8

Niche?

Back 8

The role a species plays in a community; it's total way of life

Front 9

Limiting Factor?

Back 9

In need biotic or abiotic factor that restricts the existence of organisms and specific environment a little too long

Front 10

Commensalism?

Back 10

🙂/😐

Front 11

Parasitism?

Back 11

🙂/🙁

Front 12

Mutualism?

Back 12

🙂/🙂

Front 13

Evaporation?

Back 13

The process by which water changes from liquid form to an atmospheric gas. This usually happens during the day as sun heats the atmosphere and earth

Front 14

Transpiration?

Back 14

It is the evaporation of water from the leaves of plants

Front 15

Condensation?

Back 15

Occurs when moist air begins to cool and water droplets form into clouds

Front 16

Precipitation?

Back 16

When the water droplets become large enough and when the water returns to the earths surface

Front 17

Runoff?

Back 17

The precipitation making its way back to River, stream, ocean or lake

Front 18

Seeps?

Back 18

Some of the water goes into the soil and enters plants through the roots and then the process begins again

Front 19

Nitrogen cycle?

Back 19

Nitrogen in air - soil - nitrogen fixing bacteria - amonia - nitrates - plants use as form of nitrogen to make their DNA.

Front 20

Where is the phosphorus cycle placed?

Back 20

Rock

Front 21

Carrying capacity?

Back 21

Maximum Number of organisms that live somewhere based on the food, water, and free space there

Front 22

The two types of succession?

Back 22

Primary - pioneer species

Secondary - already life there
