Answer:

Both statements are true

Explanation:

Many small tree saplings are competing for sunlight on the forest floor because tree saplings in forest floors are often deprived of adequate light as a result of the shade created by bigger trees in the forest. <em>Hence, the saplings jostle for light in order to effectively carry out light-requiring physiological activities such as photosynthesis and chlorophyll synthesis.</em>

The West Nile virus a virus that <em>generally affects the central nervous systems of birds - the primary host. It is transmitted from one bird to another through contact and by a vector - the mosquito</em>. The virus is also capable of being contracted by humans where it causes fatal neurological disorders.
