Subduction and continental collision

What are the two types of convergent plate boundaries?

Found in mid-latitudes, vegetation is primarily oak, maple, beech, 4 distinct seasons, medium amount of rainfall, cold winters, warm summers.

What is temperate deciduous forest biome?

A killing frost decimates deer populations in a forest ecosystem

What is density independent factor?

300

Energy becomes less ordered in the absence of counteracting forces

What is the second law of thermodynamics?

300

Small body size, early maturity, large broods, little or no parental investment

What are R-selected species?

300

Where two tectonic plates meet, resulting in slipping and grinding. Hallmarked by faults and earthquakes.

What is a transform plate boundary?  

300

Coniferous forests, short growing seasons, cold winters & cool summers, little rainfall, mostly small animals, some larger animals like moose.

What is boreal forest biome?

300

The boxer crab carries a pair of small anemones in its claws. When a predator approaches, it waves the anemones around which presents its stinging tentacles and deters the predator. The anemones get small particles of food from the crab when it eats.

What is mutualism?

Begins in an environment following a disturbance that dramatically alters an existing community but does not destroy all life and organic matter.

What is secondary succession?

400

A portion of the upper mantle containing especially soft rock

What is the asthenosphere?

400

Biome that has little temperature variation, receives plentiful amounts of rain, abundant primary productivity, many animal and bird species, found at mid-latitudes

What is temperate rainforest?

400

A cuckoo may lay its eggs in a warbler's nest. The cuckoo's young will displace the warbler's young, and the warbler will raise the cuckoo's young. 

What is interspecific competition?

500

A process powered by sunlight through which molecules with low-energy bonds are converted into molecules with many high-energy bonds

What is photosynthesis?

500

One ancestral population is split by some physical factor over geographic distance. Overtime, they become so different they can’t reproduce with each other anymore.

What is allopatric speciation?

500

Name the layers of the Earth

Inner core -> outer core -> lower mantle -> asthenosphere -> uppermost mantle -> crust

500

Biome of North Texas

What is temperate grassland?

500

Predators at high trophic levels can indirectly promote populations of organisms at lower trophic levels by keeping species at intermediate trophic levels in check.

What is Trophic Cascade?
