Gets its energy from the sun
Producer (autotroph)
![]()
What is this graph called?
Exponential growth
Which biome is cold, has little to no rain, and a permanently frozen ground (permafrost)
Tundra
How many levels of producers are there in the pyramid?
One level
Organisms split resources in the environment to reduce competition
Niche partitioning
Seasonal movement into and out of an area
Migration
What type of graph is this and point to the carrying capacity

Logistic growth
Carrying capacity is where is levels out
Groups of ecosystems that share similar biotic and abiotic conditions
Biomes
Why is a trophic pyramid shaped like a triangle?

population and energy decrease as you move up the pyramid
Part of the ocean with little to no light, lower temperature, deeper, fish have bioluminescence
Aphotic zone
Affects the whole community and ecosystem
Keystone species
What type of succession is shown below and why?

Primary because it starts with bare rock
Which biome has the lowest net primary production?
desert
Which animal has the lowest population in the food web?

Hawk
What are the three ways to characterize aquatic ecosystems?
Salinity, depth, whether water is flowing or standing still
Organisms that are best fit for the environment survive and reproduce
Natural selection
What type of succession is this and why?

Secondary because it starts with soil
What are the characteristics of a biome with a high net primary production?
Warmer temperature and more rain (warmer and wetter)
How many producers are in this food web?

One level
The Japanese beetle is originally from Japan but now can be found across the United States, including Tennessee. The beetle has no predators in the United States and is destroying food sources for native species. What type of species is the Japanese beetle and why?
Invasive species because it is a non-native species that is harming native species
Disappearance of a particular population in a given area, but not of the entire species globally
Extirpation
What will this population do in the future? (decline, stay stable, grow)

Decline
What biome has the highest net primary production and why?
Tropical rainforest because it has the most plants (warmer and more rain)
How many consumers are in this food web?

3 levels
What are the levels of ecological organization from smallest to biggest
individual, population, community, ecosystem, biosphere
