<span>Although it is not mentioned the location, I found the exercise on the internet with the following options:
A)weathering and erosion of park pathways
B)deterioration of the man-made structures in the park
C)pattern and timing of leaf loss in the shade trees
D)exposure of rocks and minerals found in the soil
The only effect, out of this options, that would be studied by biologists is the "pattern and timing of leaf loss in the shade trees". This is the only effect related to life, which is the subject of biology - living organisms and their mechanisms. Leaf loss is a process undergone by many trees as colder seasons, or dry seasons in the case of trees in tropical forests, approach.</span>

Bones consist of living cells embedded in a mineralized organic matrix. This matrix consists of organic components, mainly type I collagen – "organic" referring to materials produced as a result of the human body – and inorganic components, primarily hydroxyapatite and other salts of calcium and phosphate.
An omnivore eats both plants and animals!
Badgers, pandas, raccoons, and dogs are examples of omnivores I think!
