What will happen if we use resources globally at an unsustainable rate?

Converted to electrical energy
Converted to kinetic energy
Consider this food web. It is rich with animal species that fill a variety of niches within the ecosystem. Imagine that a local farmer has sprayed the area with insecticide. Predict how this might impact the food web and the roles each organism plays within it.
The entire food web would be impacted. The base of the food web, the herbivores, would be eliminated. The food web would collapse without this niche being filled.
One section of the food web would be greatly impacted: the section containing the insects and insect-eating animals. Without insects and possibly spiders, there would be no food for the toads and insectivorous birds.
One section of the food web would be greatly impacted: the section contains the insects and insect-eating animals. Without insects and possibly spiders, there would be no food for the toads and birds including the hawks and owls.
An ecological pyramid is sometimes used to show both the flow of matter and energy in an ecosystem. The pyramid narrows as matter and energy flow from the bottom to the top. Draw a conclusion about what this pyramid tells you about the energy in this ecosystem.
Energy decreases from bottom to top because some is used at each level for life processes.
Energy stays the same. Only the number of living things change.
Energy increases from bottom to top because the organisms get larger in size.

In nuclear fission, a large atom like U-235 splits into two smaller atoms releasing a large amount of energy. What causes U-235 to split into two smaller atoms?
U-235 is bombarded by an neutron, which makes U-235 unstable and it splits into two smaller atoms.
U-235 is bombarded by an electron, which makes U-235 unstable and it splits into two smaller atoms.
Two U-235 atoms are bombarded by an proton, which makes U-235 unstable and it fuses together.
