The variety of organisms within an ecosystem and biome.
organism
ecosystem
biome
biodiverse
The ability of an ecosystem to maintain its stability and structure over time.
ecosystem
sustainability
biodiversity
adaptability
A group of ecosystems with similar climates and organisms are called?
ecosystems
habitats
communities
Which biome consists of plants that grow low to the ground, cold temperatures, and permafrost (frozen soil)?
Taiga
Tundra
Temperate forest
Temperate grasslands
This biome has hot summers, cold winters, soil that supports abundant plant growth, grazing herbivores and few bird species.
taiga
grassland
decidiuous forest
tundra
Which is the correct statement for the temperate forest and tropical rainforest?
Temperate forests are adapted to survive less than heavier rainfall and cooler temperatures.
Temperate forests are adapted to survive heavier rainfall and warmer temperatures.
Temperate forests require heavier rainfall than tropical rainforests.
Temperate forests are found near the equator than tropical rainforests.
Which TWO abiotic factors determine the biodiversity of the organisms in a biome?
Select TWO answers
Sunlight
Temperature
Wind
Precipitation (Rainfall)
a small area that has organisms adapted to conditions that differs somehow from the surrounding habitat
sustainability
biome
ecosystem
microhabitat
Which is a true statement about a complex food web?
A complex food web describes describes there is a larger population of organisms.
A complex food web describes how more organisms can fulfill the same niche (role).
A complex food web describes how well organisms adapt to extreme temperatures.
Why is Food Web B less sustainable than Food Web A?
There is a smaller population in food web B.
There are less organisms that can fulfill the same niche (role) in food web B than food web A.
There are more organisms eating producers in food web B than food web A.
How would the destruction of the grasshopper impact the organisms in Food Web A compared to the organisms in Food Web B?
The organisms in Food Web A would survive just like the organisms in Food Web B.
The organisms in Food Web A would not survive unlike the organisms in Food Web B.
The organisms in Food Web A have a higher chance of survival unlike the organisms in Food Web B.
Which organisms would most likely survive if one of the plant species was destroyed?
The organisms in Food Web A would have a higher chance of survival than the organisms in Food Web B.
The organisms in Food Web A have a lower chance of survival than the organisms in Food Web B.
The destruction of one plant species will not impact Food Web A or Food Web B.
Under which TWO conditions do desert plants survive?
Select TWO answers
little sunlight
heavy rainfall
light rainfall
dry soil
The following table lists the number and variety of organisms in four different ecosystems.
Based on the table, which ecosystem is likely the most sustainable?
Ecosystem 1 because it has a greater number of plant organisms.
Ecosystem 2 because it has a greater number of plant and animal species.
Ecosystem 3 because it has a greater number of animal species.
Ecosystem 4 because it has a greater number of plant and animal species.
Biodiversity means..
The variety of life in an ecosystem
How an ecosystem changes over time
Differences among humans
Diversity of a select few species in a deserted area
A hurricane hit a tundra and a forest. A tundra is less biodiverse than the forest. Which biome would be impacted the most?
The forest because it has more species and it wouldn't be able to sustain itself as well as the tundra
They would be impacted the same
The forest because it has more producers
The tundra because it has less species and it wouldn't be able to sustain itself as well as the forest
What is sustainability?
The study of life in an ecosystem.
The inability of an ecosystem to withstand stressors.
The variety of life in the world or in a particular habitat or ecosystem.
The ability of an ecosystem to maintain its full functions and properties over long periods of time even through times of stress or disturbance on the ecosystem.
Which is an example of a biodiverse ecosystem that is sustainable?
The fish population decrease but the bears can still survive because they feed off of other prey.
The snake population decreases due to its loss of habitat. The mice they prey on increase in population.
The worm population increases causing the bird population to increase as well.
The plants in a small ecosystem do not receive enough sunlight, causing the plant species to die.
Why would a rock and hole in a tree from the same ecosystem have different types of organisms?
Both microhabitats come from the same boime.
Both microhabitats share the same abiotic factors.
Both microhabitats provide different resources to organisms for survival.
Different types of predators prey on the organisms that live in both microhabitats.
Why are there different organisms in Biome 1 than Biome 2?
Biomes 1 and 2 are located in different parts of the world.
Both biomes can support the same organisms but only different organisms were observed.
Biome 2 has higher temperature and heavier rainfall resulting in different organisms living in different climates.
The following table lists the number and variety of organisms in four different ecosystems.
Based on the table, which ecosystem is likely the most sustainable?
Ecosystem 1 because it has a greater number of plant organisms.
Ecosystem 2 because it has a greater number of plant and animal species.
Ecosystem 3 because it has a greater number of animal species.
Ecosystem 4 because it has a greater number of plant and animal species.
