How does climate impact a biome?
It plays a huge part in what grows and lives in each ecosystem or biome.
How are biomes generally named?
Biomes are named by the type of plant that grows most prolifically there.
What are some examples of biomes?
Rainforest
Savannah
Coniferous
Tundra
What do food chains help determine?
The transfer or loss of energy within a given ecosystem, food web, food chain.
What are the human interventions of biomes?
Try to control the natural environment.
Try to contain the natural environment.
Try to modify the natural environment.
By doing ^^^^^ we often do a lot of damage to the natural ecosystems.
What are crop yields?
How much an area can produce.
The food use in an area.
What must we do to crop yields?
We must increase crop yields to feed our growing population and the growing number of people with a higher standard of living.
What’s required to increase/improve crop yields?
New technologies.
Sustainable farming practices.
What did the world population hit in 2011?
7 billion people.
What is the global population expected to hit by 2050?
9 billion people.
How is sustainability a problem?
Food in not grown or distributed evenly.
Almost 1/3 of all food produced is wasted.
Food for people is used to feed animals.
^^ Eg. 30kg of grain produces 1kg of red meat.
More land is lost to urban development.
Environmental degradation.
What are new sustainable ways of growing food?
Sustainable farming practices.
More natural ways of farming.
Organic farming.
More effective use of land we already have.
More sustainable ways of water resources.
What are examples of more natural ways of farming?
Less soil degradation.
An increase in biodiversity.
Rotating a variety of crops through an area.
Cycle nutrients back into soil.
What is organic farming?
Improving the farming methods of poor subsistence farmers to increase crop yields.
