Biomes
What two living things exist within a biome?
Plants and animals
What two components are used to determine/observe the weather?
Temperature and precipitation
What is a keystone species?
A species that has a large impact on their habitat. They affect many other species.
What is biodiversity?
The variety of life
What are the 4 characteristics that define a biome?
Temperature, soil, amount of light, and amount of water.
How often is weather measured?
Daily
What is an indicator species?
Species that dramatically respond to environmental changes
What are the 3 main types of biodiversity?
Species, genetic, and ecological.
Which biome has year-round warmth, is located near the equator, and has both rainy & dry seasons?
Rainforest
What is climate?
The weather in a particular location over a long period of time
What is the role of an indicator species?
They measure environmental conditions and are indicators of environmental health
What does a biodiversity index tell you?
What does a higher index tell you about an environment?
How many species exist in a certain environment.
A higher index represents greater diversity
Which biome has four distinct seasons, many trees, and provides camouflage?
Deciduous forest
What 2 components make up a climatogram?
Temperature and precipitation
Which process occurs more quickly: primary succession or secondary succession? Why?
Secondary succession occurs more quickly because there is still soil present
What are invasive species?
How do they affect biodiversity?
Species that come from a different region of the world.
They reproduce faster than the native species and can adapt to new competition. They have fewer limiting factors.
What are the 9 major biomes?
Tundra, taiga, grasslands, deciduous forest, savanna, chaparral, rainforest, desert, alpine
What are climatograms used to show?
Changes in climate over time
What is a climax community?
A stable community that remains relatively unchanged. This is the final stage of succession.
How is a line transect used/measured?
What does a line transect tell you?
A sample of species along a specific physical line is measured.
Amount of biodiversity in a location.
