If your local environment begins to turn into a desert, what will most likely happen to the organisms in the environment?
The populations of organisms currently existing in the environment will increase.
The populations of organisms currently existing in the environment will not be affected.
The new desert environment will be unable to support any populations of organisms.
A different variety of organisms will be supported rather than the ones that currently exist.
Which statement best describes the comparison of lake and ocean environments?
The lake and ocean environments support the same organisms because they are both water and are made up of the same elements.
The lake and ocean environments support different organisms because most freshwater organisms cannot live in saltwater.
The lake and ocean environments support the same organisms, but they will look different because of the type of water.
The lake and ocean environments support different organisms because ocean organisms are blocked by land from getting into lakes.
The more diverse an ecosystem is --
the more threatened its populations are
the more similar the species will be
the more sustainable it is
the fewer varieties of species are present
A flower bed is created at a school so flowers can be planted in the autumn.

Would it be better to have more or less Producers for Biodiversity?
More
Less
If there are multiple Birds with Different Beaks What is the advantage behind the ecosystem?
It allows for great diversity among the birds, allowing the population to survive even if there is a ecological change.
It allows the birds the ability to help other birds gather food.
It enables the birds to invade the habitats of other organisms to gather food.
It gives birds the ability to change their diet from year to year depending on available food.
