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:
See explanation
Explanation:
The reaction between alcohol and acidified potassium dichromate  is a redox reaction. This reaction can be used to detect a drunken driver.
Alcohols can be oxidized to aldehydes, ketones and carboxylic acids depending on the structure of the alcohol. Primary alcohols yield adehydes and carboxylic acids while secondary alcohols are oxidized to ketones.
The colour of the acidified potassium dichromate turns from orange to green when exposed to alcohols from the breath of a drunken driver.
