Answer:
The carrying ability of an ecosystem is the overall growth rate of a biological species that can be supported by that area, provided the available food, habitat, water, and other resources.
Explanation:
A pond populated briefly by ten turtles, for such, would be sustainable for the species' population.
I'm at a loss between A & C but I'm not sure, I'd go with A
If you are checking a cell for a zero value and the cell is blank, the test evaluates to true. For example, if you have the following formula in cell A1 =IF(B1=0,"zero","blank") and B1 is blank, the formula returns "zero" and not "blank" as expected.
If the range might contain a blank cell, you should use the ISBLANK function to test for a zero value, as in the following example: =IF(ISBLANK(B2),"blank",IF(B2=0,"zero","other")) Note that the above formula returns "zero" if there is a zero value in the cell, "blank" if the cell is blank, and "other" if anything else is in the cell.
You must always use the ISBLANK formula first before you test for a zero value. Otherwise you will always return a "true" for the zero value, and never get to the test for the ISBLANK formula.
The correct options are as follows:
1. USE, B.
Land use refers to the function of a particular land, that is, what the land is been used for. For instance land can be used for agriculture, construction of roads, residential apartments, hotels, zoos, etc. Land use differs in the urban and rural settings. In the rural settings, land is usually used for farming and forestry while in the urban setting, land is usually used for construction purposes.
2. LUC, OPTION B.
The modification of the earth's surface due to land use is called LAND USE CHANGE, LUC. A lot of changes occur when man use lands for different purposes. For instance, examples of land use change include: reduction in forest biomass, conversion of forest and grassland to pasture, etc,
Answer:
I think the answer is C
''Reusing plastic bags''
Explanation:
Removing carnivores from a forest has a great impact on a environment since the population of the herbivores will increases drastically and the dynamic equilibrium of the area will be greatly effected.
If we look at choice B '' Heating homes with fossil fuels'', this will also have a big impact on the earth since fossil fuels are non-renewable and take centuries to form. Heating homes with them will result in loss of fossil fuels.
Now let's look at choice D ''Adding heavy metals to the water supply''. Heavy metals are dangerous to the human health and even cause cancer. This will cause thousands of deaths and will also have a great impact on the global stability.
This leaves choice C ''Reusing plastic bags''. This will cause less pollution and less harm to wildlife but doesn't have any big threat to the global stability. As in changing the world population or causing deaths in large numbers.
so I think choice C is the answer
