Energy and Productivity
100

A ecosystem is home to biotic components, like animals and plants, and these components, like soil and temperature.

Abiotic

100

Terrestrial biomes are grouped together through temperature and this other climate statistic

Precipitation
100

This freshwater biome is catergorized with fast-moving water, preventing plants from rooting at the bottom.

Rivers and Streams

100

The most common method that nitrogen gas is fixed is through of these, which exist within the soil, and on the roots of plants.

(Nitrogen-Fixing) Bacteria
100

Net Primary productivity is equal to gross primary productivity minus this.

Energy already consumed by producers

200

The wild boar is native to Eurasia, but was introduced in the United States, quickly becoming dominant due to its aggressive nature, generalist diet, and lack of natural predators. Because of this damage, it can be considered one of these species.

Invasive Species

200

This biome exists just along the tropical latitudes, and is known for intense heat, sparse plantlife and little to no annual rainfall.

Hot Deserts

200

These flooded freshwater areas are useful to humans because of their ability to reduce flood damage and filter water.

Freshwater Wetlands

200

Evapotranspiration includes the water that is evaporated from the surface, but also water evaporated from these sources.

Plants

200

These types of consumers often don't fit easily onto a food chain or trophic pyramid, as their diet of dead matter and waste can put them at any level.

Scavengers, Decomposers, or Detritivores

300

Remora are a species of fish that attached to the bottoms of sharks. This doesn't hinder the shark in any way, but allows the remora to eat the scraps left over when the shark feeds. This is an example of this relationship.

Commensalism

300

At high latitudes, you may find this biomes, also called boreal forests. They are mostly cold, have short growing seasons, and are dominated by large conifer trees, like pine and spruce.

Taigas

300

As ocean temperatures rise and pH changes, coral reefs are vulnerable. The process in which they die off, leaving white remains and destroying the ecosystem is called this.

Coral Bleaching

300

Combustion of fossil fuels produces carbon gases at a rate far faster than plants can remove them from the atmosphere. This can lead to global warming, as carbon dioxide is one of these heat trapping gases.

Greenhouse Gas

300

This term describes the mass of all living things at a given trophic level, and decreases and trophic level increases.

Biomass

400

Moray eels and reef sharks both consume fish as their primary food source. Eels only eat fish that stay within the coral reefs, but sharks consume the fish that live just outside the reef. This is an example of this practive of avoiding competition.

Resource Partitioning

400

In the tropical regions of Africa and South America, this biome recieves high temperatures, but only moderate rainfall. This results in a grassy terrain with occasional trees. It is also prone to seasonal rains and wildfires.

Savannah (Tropical Seasonal Forest)

400

This marine biome is one of the most brutal on earth, as organisms must endure changes to sun exposure, water level, salinity, and vulnerability to predators mutiple times per day.

Intertidal Zones

400

Excessive phosphorus in water can result in algal blooms. These blooms die off and invite decomposers to burn through the water's oxygen, creating these kinds of unlivable zones.

Dead Zones

400

List these organisms in a food chain from lowest to highest trophic level.

Rabbit, Owl, Scavenger, Grass

This ecological principle states that two species cannot compete over the same shared resource without one outcompeting the other.

Competitive Exclusion Principle

500

Biomes are different from this term, which refers to the area in which a particular species can normally be found.

Habitat

500

Lakes can be separated into different zones, like littoral, limnetic, and this one, which refers to the bottom of the lake. The ocean also has this zone.

Benthic Zone

500

The process in which dead organisms and waste products are broken down into nitrogen rich compounds in the soil is called this.

Ammonification or Mineralization

500

A corn farm generates 5000 kg of corn every year on his land. However, the farm decides to pivot to producing pork instead. Assuming 10% ecological efficiency, we can assume the same land could produce this many kgs of pigs.
