Defining Biomes
These are the two ways biomes are classified.
What is by climate and plant/animal life.
This biome has the highest net primary productivity.
What is a tropical rainforest?
This is the uppermost layer in an aquatic ecosystem where there is enough sunlight for photosynthesis to occur.
What is the photic zone?
These types of tress experience seasonal loss of leaves as an adaptation to their climate.
What are deciduous trees?
This is the very bottom of any body of water, where light may or may not penetrate.
What is the benthic zone?
This is the mean temperature and precipitation of an area.
What is climate?
This biome has the lowest net primary production?
What is a desert?
The three main criteria ecologists use to classify aquatic ecosystems are depth, whether the water is flowing or standing, and this.
What is salinity?
This is the extended period of deep sleep-like inactivity that some animals enter for the winter.
What is hibernation?
In freshwater ecosystems, this is the shallow, near-shore zone where aquatic plants can grow from the mud and reach above the water's surface.
What is the littoral zone?
This shows the mean monthly temperature and rainfall of a biome in a single view.
What is a climatograph?
To help them survive in this biome, caribou have various adaptations, such as wide hooves for travel on mud and snow.
What is the tundra?
These are brackish ecosystems that occur where rivers flow into the ocean.
What are estuaries?
What is brackish?
In a freshwater ecosystem, this zone is comparable to the open ocean zone in that it is farther from the shore where there are no rooted plants.
What is the limentic zone?
Warmer and wetter biomes have higher of this, the amount of plants an ecosystem or biome produces.
What is net primary production?
Shorter trees and plants that make up this layer in tropical rain forests have large, flat leaves to allow maximum surface for light absorption.
What is the understory?
This type of neritic ecosystem thrives in cold, shallow waters where upwelling occurs.
What is a kelp forest?
This is the vertical movement of cold, nutrient-rich water from the ocean depths to its surface.
What is upwelling?
This ocean zone begins at the edge of the continental shelf and is among the least productive ecosystems because most of it is dark.
What it the open ocean zone?
The same biomes tend to occur at similar of this global location descriptor.
What are lattitudes?
This is a biome with less rain than a tropical dry forest, but more rain than the desert.
What is the savannah?
This type of tropical estuary ecosystem of exposed-root trees and shrubs prevents soil erosion and flooding as well as providing a protective barrier between the sea and land.
What is a mangrove forest?
In the desert, some organisms avoid hot, dry conditions by going into this, a deep, sleep-like period of inactivity.
What is estivation?
Organisms living in this ocean zone must withstand tremendous extremes in temperature, moisture, sun exposure, and salinity as well as protecting themselves from marine and terrestrial predators.
What is the intertidal zone?
