Parts of an Ecosystem
Name an abiotic factor in an ecosystem.
Temperature, Wind, Rock
What succession happens after a natural disaster?
Secondary Succession
This process allows plants to take in carbon dioxide from the atmosphere to make glucose.
Photosynthesis
Organisms in this kingdom are multicellular and must obtain food by consuming other organisms.
Kingdom Animalia
Why are food webs generally more realistic than food chains?
They show multiple feeding relationships within an ecosystem.
List an example of a producer.
Mushroom, grass, tree
Name a pioneer species in primary succession.
Lichen, Moss
Burning coal, oil, and natural gas releases this carbon-containing gas into the atmosphere.
Carbon Dioxide
Animals belong to this type of organism because their cells contain a nucleus.
Eukaryotes
If the rabbit population decreases, explain how this could affect the fox population.
The fox population may decrease because less food is available.
Mushroom that breaks down dead matter is considered what?
Decomposer
What succession happens faster, primary or secondary and WHY?
Secondary - soil exists
This process releases carbon stored in dead organisms back into the environment.
Decomposition
Amoebas and many types of algae are traditionally classified in this kingdom.
What is a nucleus?
This percentage of energy is typically transferred from one trophic level to the next.
What is 10%?
What is a detritivore?
Organisms that obtain nutrients by consuming detritus, which includes decomposing plant and animal parts.
A lava flow covers an area and hardens into rock, leaving no soil behind. What type of succession is this?
Primary Succession
What body of water absorbs and stores large amounts of carbon.
Ocean
Explain why fungi are essential to nutrient cycling in ecosystems.
They break down dead material and waste, returning nutrients to the soil and environment.
Producers contain 50,000 energy units. How much energy reaches the secondary consumers?
500 Units
What is another name for a 3rd level consumer?
Tertiary Consumer
What do we call a relatively stable community that develops later in succession?
Climax Community
Explain how deforestation can affect the water cycle in an area.
It can reduce transpiration, increase runoff and erosion, and alter local water movement and storage.
Explain why a mushroom is not classified in the animal kingdom, even though it cannot make its own food.
Mushrooms belong to Kingdom Fungi because they absorb nutrients rather than ingest food like animals.
Explain why a food chain usually cannot support an unlimited number of trophic levels.
Energy decreases at each transfer, leaving too little energy to support many additional levels.
