100

A way in which carbon is added to the atmosphere.

Cell Respiration

Combustion

Decomposition


100

An organism that is can do photosynthesis or chemosynthesis

Autotroph 

100

List one example of a biotic factor and an abiotic factor.

Biotic: Anything living (animal, plant, fungi, bacteria, Protista)

Abiotic: Anything nonliving (Rocks, sand, water, air, sunlight)

100

The maximum population an ecosystem/habitat can support.

Carrying Capacity (K)

100

Carbon dioxide dissolving in the ocean causes the Ph to _______________. 

This is called _______________. 

Fall/Lower

Ocean Acidification

200

Form of nitrogen that cannot be used by most organisms. 

Nitrogen gas (N2)

200

What trophic level are herbivores?

Primary consumers. 

200

Biotic and Abiotic factors functioning together in an area would be considered a(n)

Ecosystem

200
Fluctuating population size above and below the carrying capacity

Dynamic Equilibrium

200

Difference between global warming and climate change

Global Warming is only focuses on temperature, climate change looks at weather events, temperature, rain, etc. 

300

Bacteria that turns Ammonia (NH4) into a form a nitrogen used by plants Nitrates/Nitrites (NO3-, NO2-)

Nitrifying Bacteria

300
Grass gets eaten by a cricket which gets eaten by a frog which gets eaten by a snake. 


What trophic level is the frog?

Secondary Consumer

300

Name one of the two elements that can cause algae blooms in aquatic ecosystems due to fertilizer runoff. 

What is this process called?

Nitrogen and Phosphorus


Eutrophication

300
What are the three differences between primary and secondary succession?

Secondary is faster, starts with soil, and has different pioneer species. 

300

Species introduced to a new habitat that cause environmental harm

Invasive species

400

Biogeochemical cycle that does NOT cycle through the atmosphere. 

Phosphorus cycle

400
How much energy is LOST between each trophic level on a food chain. 


How much energy is SAVED?

90% Lost (Heat, life processes)

10% Saved

400

In aquatic ecosystems where is biodiversity the highest?

A: Close to the coast.

B: Open Ocean far from the coast. 

Why?

A) close to the coast. 

Diverse habitats, sunlight can reach seafloor, more nutrients and food sources. 

400

Which is the most stable community?

Lichens

Mosses/Grasses

Tall hardwood trees

Tall hardwood trees (likely part of a climax community)

400

Term that describes the loss of forest, usually due to logging or clearing for agriculture. Can lead to erosion. 

Deforestation

500

In the summer in the northern hemisphere the amount of CO2 in the atmosphere will be _________________ than in winter because _________________. 


Lower, more photosynthesis occurs in the summer which removes CO2 from atmosphere. 

500
If a pollutant or harmful chemical is introduced into a food chain, which organisms will be MOST affected. Those at the bottom of the chain (producers, primary consumers) or those at the top of the chain (secondary/tertiary consumers). 

What term describes this effect?

Top of the food chain

Biomagnification

500

Which of the following is NOT a characteristic of life.

made of cells, movement, metabolism, reproduction, homeostasis, contains DNA, growth and development, responds to stimuli, evolves over time.

Movement

500

1. A fire burns a forest to the ground. Is this primary or secondary succession?

In what order would the following plant life grow back?

Large trees, grasses, bushes/small plants, small trees. 

Secondary

Grasses, bushes/small plants, small trees, big trees. 

500

List an example of the following types of pollution:

Air

Land

Water

Air: Burning fossil fuels (cars, trucks). Smoke. CFCs

Land: Litter, Landfills, mining/construction waste. 

Water: Oil Spills, Pesticide runoff. Sewage, Plastics.
