Answer:
C. More young children live in Country 1 than in the other countries.
Explanation:
The described graph shows that more young children live in Country 1 than in the other countries. This is clearly stated in the first paragraph: <em>This is the greatest percentage of any 4-year age span in all three countries.</em> This automatically means that options B and D are incorrect.
Option A is the second-best one. However, the fact that there are more young children in Country 1 doesn't necessarily mean that their death rate is lower. It could be, but correlation doesn't equal causation. There are more young children probably because the younger population is more present in that country and more children are born.
This is why option C is the correct one.
Answer:
Invasive species in time destory biodiversity of an ecosystems
Explanation:
So lets go over what each answer is:
Invasive species are species that invade a ecosystem, and can harm other species and take over resources.
Populatiuons are what make up an ecosystem. There are many populations in a single ecosystem.
Biotic factors are the living things found in the world.
Abiotic factors are the opposite, being the nonliving things found in the world.
Looking at these, which would eventually destroy the biodiversity(variation of species) of an ecosystem?
This would be invasive species, for it is the only answer that harms it's ecosystem.
And this is correct, for invasive species often times can cause extiction of species, or even whole ecosystems.
For example of an invasive species, if a tree-consuming and widly reporudcing insect that lives in plains, invades a pine forest, it will eventually kill off all the trees in the area.
This wont only kill off the pine trees, but harms and could potentiallu kill the species that depend on the pine trees for survival.
Answer: invasive speices.
Hope this helps!
