C. Fewer habitats for wild animals to live in
Explanation:
Biodiversity does not directly impact humans in that there are fewer habitats for wild animals to live in. This is a direct impact on animals and not humans.
Biodiversity is the variation of life forms in an area. It is measured by the ability of the ecosystem to sustain different life forms and keep their interaction with the environment.
It helps to maintain and sustain life.
To humans, reducing biodiversity;
- reduces the potential of medicine derived from other organisms. When their habitat is lost, we lose them.
- fewer ecosystems to appreciate for beauty and recreation. It leads to loss of the ecosystem.
- fewer wild food species for humans to eat.
Loss of habitat directly affects wild animals and not man.

Answer:
3.89 kg P2O5 must be used to supply 1.69 kg Phosphorus to the soil.
Explanation:
The molecular mass of P2O5 is
P2 = 2* 31 = 62
O5 = 5 *<u> 16 = 80</u>
Molecular Mass = 142
Set up a Proportion
142 grams P2O5 supplies 62 grams of phosphorus
x kg P2O5 supplies 1.69 kg of phosphorus
Though this might be a bit anti intuitive, you don't have to convert the units for this question. The ratio is all that is important.
142/x = 62/1.69 Cross multiply
142 * 1.69 = 62x combine the left
239.98 = 62x Divide by 62
239.98/62 = x
3.89 kg of P2O5 must be used.

water evaporate
physical change is just change between solid/liquid/gas, other two are chemical changes
