What is the source of energy for any food chain?

the sun 

100
What is the pH of acid rain?

less than 7

If a group of organisms are all of the same species, this group is referred to as a 

population

Most plants are autotrophs. What does this mean?

autotrophs make their own carbohydrates rather than needing to eat carbohydrates. autotrophs accomplish this through photosynthesis or chemosynthesis.

Barnacles attach to a whale's skin to get a place to live and access to food as the whale moves through the ocean. The whale is unaffected. What form of symbiosis?

Commensalism

200

The direction of arrows in a food chain or food web indicates what?

the flow of energy

200

Name one chemical that causes acid rain

Sulfur dioxide or nitrogen oxides

300
The sun would be considered (biotic/abiotic)?

abiotic

300

An organism that eats plants is referred to as a(n) producer/consumer/decomposer

consumer

Epiphytic orchids, like some types of orchids, grow on trees to get better access to sunlight, while the tree is not harmed or benefited by the orchid's presence. What form of symbiosis?

Commensalism

300
A carnivore is an example of a producer/consumer/decomposer

consumer

300

Does acid rain always fall where the pollution originates?

No. Wind carries the chemicals in the air to other locations. 

400

Things that impede the unending growth of a population are called

Limiting Factors

400

If an organism cannot properly digest plants / cannot gain nutrition from plants, but eats animals and gains nutrition from animals, that organism is a(n)

carnivore

The acacia tree provides ants with food and shelter in its thorns. In return, the ants protect the tree from herbivores and other insects. What form of symbiosis?

Mutualism

400

A student draws a food chain with three arrows pointing at eagles. What does this indicate?

The eagle consumes the three organisms from which each arrow originates

400

Explain why acid rain is considered a significant issue?

It changes the pH of aquatic ecosystems, altering the ecosystems, biomagnifying, and potentially reducing biodiversity by killing off many organisms. 

500

The maximum sustainable number of organisms of a given species that an ecosystem can support is referred to as  

carrying capacity

500

An organism that secretes chemicals that break down dead plant and animal material to gain nutrients and also supply nutrients to the soil / ecosystem 

decomposer

500

the tapeworms in an animals intestines are different than the microbiome bacteria in an animals intestines. Which form of symbiosis for each case?

Tapeworm = parasitism

microbiome bacteria = mutualism

500

Scavengers are autotrophs/heterotrophs and only eat _____________

heterotrophs, dead organisms

500

Explain why population increase is significant to acid rain?

More people = more production/transportation/industrial and commercial demand, so more of the actions that produce the chemicals that cause acid rain, hence more acid rain and the rain is more acidic.
