For science, we have to create an ecovillage..
1) sustainable buildings: how can we build houses/buildings without causing too much harm on our environment…
2) food: how we can have a sustainable diet by not damaging ecosystems.. how food will be grown, distributed, and consumed… what types of agricultural techniques need to be adopted to ensure a sustainable food supply?
3) green energy: what technologies can be used to minimize energy use
4) water management: how the ecovillage will access and distribute water. how will drinkable and non drinkable water be separated?..
5) waste management: how waste will be removed from the ecovillage.. what forms of eliminating would be the best and most effective? how will the 3 Rs be enforced? (reuse reduce recycle)
6) restoration: how can we restore an ecosystem destroyed naturally or by humans? how can elements of the eco village be used to recreate niches.. can any keystone species be supported?
thank you guys for having the time to read this.. you already read it so might as well answer some of it so it wont be a total waste of your time 🙂 links/URLs would be greatly appreciated.. this is due by tomorrow so please help 🙁

For science, we have to create an ecovillage.. We decided to build our ecovillage in Calgary, Alberta because it’s the cleanest city in Canada… We need some ideas for
1) sustainable buildings: like how can we build houses/buildings without harming our environment… i already got some few ideas on how to build a sustainable building by reconstructing abandoned lots or farms, using recycled materials to build houses/buildings like recycled wood and stuff..
2) food: how we can have a sustainable diet by not damaging ecosystems.. how food will be grown, distributed, and consumed… what types of agricultural techniques need to be adopted to ensure a sustainable food supply?
3) green energy: what technologies can be used to minimize energy use and how can we communicate and access to the ecovillage by using green energy… i already have some few ideas which are solar panel-generated energy, please help me think of other ideas
4) water management: how the ecovillage will access and distribute water. how will drinkable and non drinkable water be separated? ideas: they can be separated into 2 water systems, one fore drinkable and nondrinkable.. water would be purified by the water compound and tested by the federal state government
5) waste management: how waste will be removed from the ecovillage.. what forms of eliminating would be the best and most effective? how will the 3 Rs be enforced? (reuse reduce recycle)
ideas: diverts organic waste for treatment in a biogas plant, which is then transformed into fuel for city buses. Also, methane gas from the landfill is collected and converted to electricity.
6) restoration: how can we restore an ecosystem destroyed naturally or by humans? how can elements of the eco village be used to recreate niches.. can any keystone species be supported?

1. Which of the following are biotic factors and which are abiotic factors? (1 point)
Rain and grass are biotic; wind and humidity are abiotic.
Algae and fungi are biotic; temperature and rainfall are abiotic.
Oxygen and sunlight are biotic; maple trees and spiders are abiotic.
Fish and whales are biotic; plankton and bacteria are abiotic.
2. Why is it useful for an ecologist to identify the keystone species in an ecosystem? (1 point)
The keystone species is only important in early stages of succession, and so the ecologist can safely ignore changes in its population at later stages.
The keystone species is the most susceptible to pollution, and so its numbers give an indication of the levels of pollutants in an area.
The keystone species is critical to maintaining the stability of an ecosystem, and changes in its population indicate changes in ecosystem health.
The keystone species is important for the cycling of matter and must be maintained or the biogeochemical cycles will be affected.
3. Competition over resources occurs between organisms (1 point)
participating in an herbivorous relationship.
forming a symbiotic relationship.
attempting to occupy the same niche.
initiating primary succession after a disturbance.
4. The lowest trophic level in an ecosystem (1 point)
has the lowest quantity of stored energy.
has the greatest biomass.
is made up of heterotrophs.
contains detritovores.
5. What is true of the energy that is passed from one trophic level to the next in a food chain? (1 point)
About 10% of the energy passed from one level to the next is released as heat.
About 10% of the stored energy of one level becomes stored energy at the next higher level.
The energy at each level increases by about 10% with each move up in trophic level.
The total energy at all trophic levels is constant, but only about 10% is available for use by organisms for life functions.
6. Autotroph is to producer as heterotroph is (1 point)
herbivore.
consumer.
decomposer.
carnivore.
7. Which of the following is true of population cycles? (1 point)
Population cycles signal an imbalance in an ecosystem.
Keystone species are necessary to establish population cycles.
A new species introduced to an ecosystem tends to stabilize population cycles in the ecosystem.
Population cycling helps maintain a healthy ecosystem.
8. An example of a pioneer species is (1 point)
a sparrow.
a lichen.
an earthworm.
a spider.
9. Why are human disturbances often of more concern than natural disturbances? (1 point)
Human disturbances last much longer than natural disturbances so that a damaged ecosystem may have little or no chance of recovery.
Human disturbances are stronger than natural disturbances and so the recovery needed is much greater.
Human disturbances often cover much wider areas than natural disturbances, which means that more ecosystems are affected.
Human disturbances affect all types of ecosystems, whereas natural disturbances are limited to certain types of ecosystems.
10. Suppose a particular community is concerned about a fox population that kills and eats chickens on the local farms. What is the best course of action by this community? (1 point)
Kill the foxes.
Trap and transport the foxes out of the region.
Introduce rabbits as an alternative source of food for the foxes.
Build enclosures for the chickens that the foxes cannot access.
