100

This is a measure of the NUMBER of different species present in a habitat.

What is species diversity?

100

This group of organisms carries out photosynthesis and supports food webs.

What are producers?

100
Unfettered growth of a population 

What is exponential growth?

100

This group of winged insects is more populous (moths or butterflies)

What are moths?

100

This rodent eats tree bark and defends itself with quills.

What is the porcupine?

200

This is a comparison of the relative number of individuals of each different observed species in a habitat.

What is species richness?

200

These groups of organisms are heterotrophic, they obtain energy from the food they eat.

What are primary and secondary consumers?

200
Rapid growth of a population slowed by an environment's carrying capacity

What is logistic population growth?

200

This important ecological function is performed by moths

What is nighttime pollination?
200

This tiny mustelid changes to white in the winter

What is the ermine?

300
The presence of a forest shrub layer, understory, and overstory.

What is the vertical structure of a forest?

300

Only a small percentage of the energy stored at a trophic level is passed on to the next.

What is the 10% rule?
300
Natural disasters represent this type of growth inhibition

What is a density independent limitation?

300
The antennae of a moth can be described in this way

What is feathery?

300

This rodent looks like a beaver, but is much smaller and distinguishable by its rat-like tail.

What is a muskrat?

400

What are forest services?

Recreation and forest products like timber or paper.

400

This is how most of the energy from a trophic level is lost.

What is the release of heat?

400

These are density dependent factors that can limit a population's growth.

What are disease, predation, and competition?

400

This is the most common maple tree in the state of Maine.

What is the red maple?

400

This large herbivore, while common in southern Maine, is actually declining in the northern part of Maine.

What is the white-tailed deer?

500

What is a forest function? 

What is recycling carbon and recharging ground water?

500

A group of individuals from different species living together

What is an ecological community?
500

This bounds logistic population growth

What is the carrying capacity?

500

This maple tree is considered invasive due to its rapid ability to spread into a forest

What is the Norway maple?

500

This large feline is found in northern Maine's dense coniferous forests, feeding on snowshoe hares.

What is the Canada lynx?
