Biomes

100

This biome is characterized by warm weather year round, and constant high amounts of precipitation. It is found in the tropics. 

Tropical Rainforest

200

This biome has low biodiversity due to its extremely low precipitation. It is often found in the tropics

deserts

300

This biome is characterized by freezing temperatures year round and a permanently frozen layer of soil called permafrost 

Tundra

400

Seed dispersal often occurs by the wind in this temperate biome

grassland

500

This tropical biome is characterized by wet and dry seasons, compact soils, large mammals, and animals with adaptations to cope with periods of low precipitation  

tropical grasslands (savannah) 

Biomes marine

100

This zone is where most of the PHOTO-synthesis occurs in the world 

photic zone (of the open ocean) 

200

This zone is near the coast and has the highest nutrient content of any marine biome

intertidal zone

300

This zone is too deep for photosynthesis to occur. Organisms living here depend on chemical energy from inorganic sources on the sea floor or from falling organic matter above 

aphotic zone 

400

As you get __________ in the ocean, you get less biodiversity

further from the coast, deeper

500

This biome begins at the edge of the continental shelf 

open ocean

Abiotic Factors

100

The warmer and ________ a biome, the more biodiversity one can expect (think about a tropical rainforest) 

wetter

200

Depth in the ocean controls pressure and access to ___________

sunlight

300

During the dry season, savannahs are more prone to this natural and destructive phenomena  

wildfires

400

In the ocean nutrient availability is highest near the _________

coast

500

Estuaries are wetlands where rivers and seas meet. Organisms living here need to be adapted to this abiotic factor

salinity (salt)

Biotic Factors

100

Plants in the understory of the tropical rainforest have broad leaves to capture more 

sunlight

200

Cacti in deserts have modified leaves (spines) that help them to protect this resource

water

300

Many plants in temperate grasslands require this during the dry season for their seeds to germinate 

wildfires

400

Temperate forests have rich soils because they are primarily made up of this type of tree. 

Deciduous 

500

Plants living the tundra are often short because of the strong winds and because of this stunted plant organ

roots

Food webs

100

These organisms are able to convert inorganic sources of energy into carbohydrates 

producers, plants, autotrophs 

200

These organisms eat producers 

primary consumers, herbivores

300

Another name for all consumers 

heterotrophs 

400

These organisms are able to eat both plants and animals

omnivores

500

Without these organisms, energy and nutrients cannot reenter the food web when organisms die 

decomposers
