Biome Characteristics
What is a biome?
A large area with similar climate, plants and animals.
What is an organism?
A living thing
What is deforestation?
Clearing of trees
What do bees collect from flowers?
Nectar and pollen
What gas is most responsible for climage change
Carbon Dioxide
Which biomes has the highest level of biodiversity?
Tropical Rainforests
Give an example of a producer in a food web
A plant, tree, or flower
Name one human activity that damages biomes/ecosystems
Agriculture, deforestation, urbanisation, pollution, mining
What important process do bees perform?
Pollination
Give an example of an extreme weather event
Flood, cyclone, drought
Distance from the equator, Altitude, distance from Coastline
Why is biodiversity important in ecosystems?
it helps them be stable and resilient to change.
Why is the demand for food and land increasing?
Population increase
Approximately what proportion of the world's food crops rely on pollination?
75%
Name two impacts of climate change on biomes
Extreme weather, droughts, flooding, bushfires, melting ice, sea level rise
Why do polar biomes have very little plant life?
Low sunlight concentration which plant need for energy through photosynthesis.
Explain what could happen if one species is lost from an ecosystem
The food web will be disrupted, other species may decline, the ecosystem may collapse.
Give two impacts of deforestation on ecosystems
Loss of habitats, loss of species, disruption to food webs, soil erosion, increased carbon emissions.
Give two reasons bee populations are decreasing
Pesticides, habitat loss, climate change, disease, parasites, invasive species.
What is the different between the weather and the climate?
The weather can change every day
Why do tropical deserts have a much lower biodiversity than topical?
What does it mean if organisms are interconnected?
They rely on each other and impact one another.
Explain how urbanisation can impact food insecurtity
land that could be used for agriculture is now used for buildings and infrastructure
Explain how fewer bee populations could affect humans
Reduced food production, less food variety, higher food prices, decline of ecosystems
Explain how planting trees can help reduce climate change
Trees absorb carbon dioxide during photosynthesis, they store carbon and reduce gasses in the atmosphere.
