Viruses are not considered "alive" because they lack many of the properties that scientists associate with living organisms. Primarily, they lack the ability to reproduce without the aid of a host cell, and don't use the typical cell- division approach to replication.
Its definitely not A, nor is it D because food webs and food chains can be either land or aquatic animals. i think its B because a food chain goes up and a food web includes more organisms
Hello there,
It seem's to me that your answer would be "<span>D. The land slopes gently."
As you focus very hard and steady on the picture, I see a little turn to the right, this can indicate that there is a slight slope.
Hope this helps.
