---|---|
Of these three biomes(Temperate Deciduous Forest, Coniferous Forest, and Tundra), Why would you expect Tundra to have the FEWEST number of animals in each population | It has the Least amount of food |
What are biomes? | Large ecosystems that have distinctive organisms and a particular climate |
What is a tertiary consumer in a food chain | a carnivore at the top most level in a food chain that feeds on other carnivores |
Tropical rain forests are home to thick plant growth. Many such forests have poor soil that contains few nutrients. How is poor tropical rain forest soil able to support thick plant growth | Decomposers quickly recycle nutrients of dead organisms |
Rain forests contain more species of trees than any other biome. However, scientists have found that the soil of the forest floor is relatively nutrient poor. What could MOST likely account for this | The nutrients are being utilized by the plant life |
Give a brief definition of the tundra biome | Average winter, low temp in summer, simple structure, no deep roots, few varieties of animals, plants include small shrubs, mosses and grasses |
Which biome has the most vegetation? | forest |
Which biome has a low precipitation and high temperatures? | desert |
an area is semiarid, has few trees, and is home to ground-nesting birds. This area is MOST likely part of which biome | grassland |
Which biome gets more rain grassland or desert? | grassland |
High average daily temperature and heavy annual precipitation are found in which biome? | rainforest |
Which environment is BEST for an organism that sleeps during the day and digs holes in the ground for shelter? | desert |
In the grassland ecosystem, organisms of the same species eat the same food , When there is a lack of rain, what is most likely increased | Competition for resources |
One hot summer, a grassland experienced a drought . What MOST likely happened in the ecosystem | the competition for food among primary consumers increased |
How will a thriving grassland ecosystem MOST likely be affected by the drought | Animals will be forced to migrate |
What environmental factor would MOST likely prevent an orange tree from surviving in the desert | the lack of moisture |
Why do few plants grow on a tropical rainforest floor | Layers of trees keep sunlight from reaching the forest floor |
Estuaries are called "nurseries of the sea" because many species lay eggs and develop their young in estuaries. What features of estuaries support this roll the most | Abundant shelter and concentrated nutrients |
how does the water in an estuary compare to the water in open ocean | estuaries have more concentrated nutrients and less concentrated salt |
Where is the biological magnification of pollutants most likely to be the greatest | In an estuary |
List an abiotic factor that can influence the quantity of fish a pond can support | Quality of water |
list an abiotic factor that most limits the number of frogs living in a pond | Temperature of the water |
What type of ecosystem has the greatest variation in temperature from its top to its bottom | Ocean |
